关于柯美650 7165 7255 7272 7155有低灰、漏粉严重问题解决方案

关于柯美551/650/5510/7165/7255/7272/7155/7085等等系列的机器换粉后就出现有低灰、漏粉严重以及漏在转印架上的问题解决方案
以上系列的机型，尤其是在换新粉（或代用粉）就出现底灰、漏粉等等原因。

这不是鼓的问题，不是载体问题，就算你换个新鼓也会有底粉的。

原粉印完就不行，有这么巧吗？我们帮人就帮到底三。

这机器对粉要求高些，第一次加代用粉后会不停的往显影箱里加粉，所以一般换一种牌子的粉就要调整过。

跟25方式关系不大，如果调过了，就先把25里的参数调回去。

要在36方式里调的，先拨掉粉盒下面的加粉插头后复印了再说，显影箱里面至少能印一千多张。

很淡了再插上插头，再拆出鼓组件来搞次大清洁，最重要的是鼓架下面左边的两个传感器，对着鼓的，它们是查测墨粉浓度的，要擦干净。

全部清洁好再装上去调整。

进入36找到里面的感光鼓自动调整。

也就是调电压的下一项（电压是在第一行，这是第二行），点进去有好几个要调，但不难，都是自动调的，把里面有写自动调整的先启动（就是调整）一下，最后调那项叫订书盒什么什么的，应该也是最后一项，它会自动调整6至8分钟，调整完成后会提示你复印十张白纸，照做吧，因为问题就要解决了！印完关机开机
就OK了。

注：看事容易做事难，如果对机器不太熟，最好找个有维修经验的朋友帮忙一下，不要省那一顿饭。

我打字太慢，回您这花了半个多小时，如果这对您有帮助也不用太感动，也不一定要送RMB，但希望下次您遇到有需要帮助的人也凭自己的能力用心去帮助别人就好了，社会需要热心肠！

复印机维修资料大全

第一、复印机出现故障后的检查与维修步骤：复印机出现故障后，总有一种是主要的故障，抓住这个主要的故障进行分析，即可找到故障原因和排除的方法，我们一般可通过以下几条途径来查出故障的原因并排除之。

检修时应遵循先易后难的原则并逐步缩小范围，最后集中于某一点上。

一、了解情况维修机器前首先应认真询问操作者有关情况，如机器使用了多久，上次维修（保养）是在什么时间，维修（保养）效果如何，此次是什么情况下出现的故障。

还要认真翻阅机器有关维修记录，注意近期更换过哪些部件和消耗材料，有哪些到了使用期限而仍未更换过的零部件。

二、检查机器情况了解清楚以后，即可对机器进行全面检查，除了机内短路、打火等故障外，都可接通机器电源，复印几张，以便根据其效果进行进一步分析。

对于操作者提供的故障现象应特别注意，并在试机时细心观察。

三、准备工具在对机器进行检查的基础上，一般可对故障现象有个大致的了解，即可知道维修时需要哪些常用的专用工具，准备好将要使用的工具和材料后即可进行检查维修工作。

四、机器故障自检目前绝大多数复印机都装有彩色液晶显示面板，并设有卡纸等故障自检功能，一旦机器某一部件失灵或损坏，都能以字母数字告诉操作者。

比较常见的是故障代码，如NP系列复印机的故障代码为“E0~E8等，理光系列则以”U“加数字为代码，这些代码一出现分别表示印刷电路板，传感器、开关、接插件等工作状态异常，需要进行调整或更换。

作为机器的使用者，见到这些故障代码，应立即停机，关掉电源，请维修人员进行检修。

如果是自己修理，则必须找到与所使用机器型号相同的维修手册或维修说明书，在书中查到故障代码所表示的内容，再检查相应的零部件、电路板或电子元件。

第二、常见“共性”故障的检修由于复印机的种类和型号繁多，各制造厂生产的复印机各不相同，即使是同一个生产厂家生产的不同型号复印机也不完全一样。

因而在使用中所出现的故障现象还是有一些差别，这里仅对共性的、一般常见的故障及其成因和排除方法加以介绍。

分享复印机维修资料（Share copier maintenance materials）Share copier maintenance materialsAnalysis of common troubles in copying machine1 fault fault phenomenon: a Ricoh FT-4495 copier toner, recently because, replace the toner, soon no powder lights still bright, suggesting that toner is not enough, the main motor idling stop, can not copy.Fault analysis and Troubleshooting: according to the fault phenomenon, it is estimated that the toner cartridge is not installed in place, resulting in reloading toner cartridges, and check the toner amount is correct, the boot to try again, the failure is still. Open the front cover and observe the transmission of the powder feeding mechanism. It is found that the rotating powder feeding roller gear can drive the driving wheel and the stirring gear to rotate, indicating that the fault appears on the driving part of the stirring gear to the toner box. Remove the toner cartridge, toner cartridge between found gear broken and powder stirring gear, resulting in the toner powder stirring roller does not rotate, the toner cartridge for powder, the machine does not work, no powder toner cartridge to retrieve the original, will pour into the original toner cartridge, ink cartridge reloading, troubleshooting.Summary: when you change the toner cartridge, you must first gently shake the new box, so that toner distribution evenly, and turn the powder roller, so that it is flexible rotation, no dead center, you can install. Otherwise, will cause a stir roller gear broken phenomenon, causing unnecessary losses. Theworking process of the copierThe working process of the copier mainly consists of the following parts: (in the order of copying)Charging parts (high voltage generator, electrode rack, motor wire)Bring a uniform charge onto the surface of the drum.Exposure unit (scanning exposure lamp, reflector, lens)A reversal potential image is formed on the surface of the photosensitive drum according to the original image. (the previous chapter has already explained)Developing parts (developing device, high voltage generator)The latent latent image of the drum surface is converted into a toner image. (the previous chapter has already explained)Feeding parts (motors, paper wheels)The motor drives the paper wheel to feed the copy paper into the machine and prepares the ink transfer on the surface of the drum to the paper for the next step.Transfer parts (high voltage generator, electrode rack, motor wire)By transferring the electrode, the surface of the copy paperis uniformly charged with the charge of the toner, and the toner image on the photosensitive drum is transferred to the copy paper.Separation unit (high voltage generator, electrode rack, motor wire)Because the surface of the copy paper and the photosensitive drum are all charged and the polarity is reversed, the copy paper is difficult to separate from the photosensitive drum during the copying process. Therefore, separate measures should be taken to separate the copy paper from the drum. Earlier copiers were mechanically separated but easy to jam; current copiers were electrically separated. The separation current contains high frequency AC and fixed DC components.Cleaning parts (cleaner)Clean the residual toner on the surface of the sensitive drum and prepare for the next copy. It is impossible for all copiers to transfer the toner on the drum surface to the copy paper by transfer. Therefore, the drum surface has residual toner, not clean, it will affect the quality of the copy later.Fixing parts (fixing heat sticks, pressure bars, heaters)The toner image on the copy paper is fixed on the copy paper by fixing,So as to keep it. If the image is not touched, the image on the copy paper falls off. (so fixing requires a certain amount oftemperature and pressure.)The process of copying also involves many auxiliary processes:Power out unit (full exposure light)Remove the residual potential on the surface of the photosensitive drum and prepare for subsequent copying. Otherwise, the copy will contain a residual image or bottom ash.Edge deleting parts (such as inter image side lights)The copy has the front, front and rear sides, back ends, or narrow portions of the blank, so the surface potential of the unnecessary photosensitive drum needs to be removed by using an image like edge elimination lamp.Copier daily usage skillsDigital copier, compound machine office in small and medium-sized enterprises, are used frequently, and sometimes need to purchase the machine or buy supplies, which is a problem we procurement staff, how to choose the suitable company machine, how to buy genuine supplies and so on. Today, I give you the whole is a more comprehensive information, there are daily use skills, but also how to buy supplies and machines of some experts point of view inside. We hope to have some help to the daily office.Troubleshooting and analysis troubleshooting experience for copiersCopier occasional jam is not a fault, but if the frequent jam, you need to check and repair. First of all, it should be clear where the paper jam is for paper parts, paper parts, or fixing parts, of course, the three parts such as parts are obviously damaged, can be replaced. But in many cases, the entire transmission mechanism without any obvious damage to the parts, but also without any obstacles, but frequently jam paper, not only affect the efficiency of work, but also affect the working mood of the operator. For maintenance personnel, sometimes several factors are often intertwined to influence diagnosis.Copier1., paper for paper jam: this part of the cardboard, involving many aspects, first of all should check whether the used paper is standard (such as paper weight, size, dry degree), test machine use standard paper. Cartons are irregular and cause paper jams. You can try to put only a few sheets of paper box, then paper, if not rub or not in place, it can determine a paper rubbing wheel or a paper rubbing clutch problem; if a paper rubbing paper in place, but can't move on, it is estimated on roll sliding or para clutch failure caused by. For some models, the paper appears askew and may be caused by unequal clamping forces on both sides of the carton. In addition, many operators in the carton box, the force is too large, resulting in a few cartons of paper from the claws, it will inevitably cause cardboard.The 2. part: such as cardboard paper in this area often jams and should aid in the door switch plate (a tool), carefullyobserve the site operation, excluding factors are in round conveyor belt and guide, should check the separation mechanism. Because of the different types of copiers, the separation methods should be differentiated. At present, there are three kinds of separation models in China, such as vacuum separation, separation, separation and charge separation. Specific inspection and maintenance methods will not be repeated here.3. fixing parts cardboard: when the fixing roller separation claw for a long time after use,The end of its blunt or small spring fatigue failure, will cause cardboard. For some models, the paper feed roller after a long time to use serious wear and tear, will also frequently jam. As for the fixing roll, the jam caused by serious scaling is common in the general machine type.Buy Copiers how to strengthen the authenticity of supplies?Don't pay attention to the price to buy the copier, some informal copier dealers, in order to earn greater profits, even the machine modification or replacement of fake supplies, this not only affects the service life of the copier, copier will also increase the failure rate. Now we will provide you with several items to buy Copiers attention:First, see if the copier has been opened or sealed, and the original machines are sealed by single channel.Second, the original copier toner cartridges are wrapped in zinc skin, the packaging is neat.Third, buy fake toner copier, copy effect, black and white depth and ordinary copiers, the effect is much worse.Fourth, the use of false toner, there will be a special smell.Fifth copier copy number, and technical parameters are different, this is the customer is not easy to note, but also the most important way of identification.Several problems should be paid attention to when buying copiersNowadays, there are many kinds of brands in the copier market, and the functions are more and more. What brand of copiers should a small and medium-sized enterprise choose?This is also from several points of view: first, according to the use of customers, divided into low, medium, high-speed copiers. Each month load capacity is different, generally 10 thousand within the choice of low speed machine; 2--5 million to select medium speed copier, even if the user dosage is larger, also can meet the needs. 5-10 must buy high-speed machines. Second, function, choose a copier, must look at the copier function is not able to meet your use, such as now can add, print, scan, fax and other functions. Copier life expectancy of 5-8 years on average, but also consider the future increase in workload can meet, or provincial level and so on. Third, the copier consumables are satisfactory to you? Some copiers exist machines, cheap, but the latter use cost is amazing, this is generally based on the actual use of customers.About customer service service these big brands are similar, Canon, SHARP, Toshiba Ricoh, is a year of free home repair, but KYOCERA copier is three years free on-site maintenance, so once again remind you, buy Copiers to ask the copier warranty time.Method for resetting special fault code of SHARP copierSpecial fault code 700/800 series of SHARP copiers are mainly HX (H1 H8, heat roller fixing device fault), Lx (L1-L6, micro switch / photoelectric switch fault, Ux (U1U2), low battery voltage or data transmission fault) and Pl (exposure lamp temperature fuse abnormal). Among them, U1 used the command "13" reset, other special instructions for fault code "14" reset.SHARP 1000/2000 series copier special fault code, mainly HX (H2-H4, hot roller fuser fault) and U2 (memory read and write failure), which U2 with instructions "16" reset,Other special fault codes are reset by instruction 14.SHARP 7000/8000 series copier special fault code, mainly HX (H3, H4, hot roller fuser fault) and U1 (battery voltage is low). The U1 is reset by the instruction "13", and the H3 H4 is reset by instruction "14". The sequence of the reset operation is shown in the figureIn addition, a special fault code for SHARP Z60 copier with U (motherboard battery low), L (micro switch fault) and H (failure of hot roll fuser (F), fixing the lamp or temperaturefuse) said, with "1" reset command. Reset, in order to press the clear key, duplicate keys, (addend key), (digital subtraction key) key "1" and the copy button:(1) the key should be pressed within 5 seconds:(2) SHARP, 750, 770, 771, 780, 781, 825 and other copiers press duplicate keys, other copiers press the pause button;(3) at this time all the display on the operating board disappears, the main motor stops rotating, the copier is ready to receive instructions (when the main motor rotates, copy)The machine does not accept instructions;(4) SHARP 1000/2000 series 1016, 1020, SHARP copier includes 1025, 1116, 2014, 2020, 2022, 2027, 2040, 2114, 2214 SHARP 7000/8000 series copiers copiers; including SHARP 7320, 7370, 7700, 7750, 7800, 7850, 8570, 8870 copiers.Inspection and maintenance of paper jam in copierIt is believed that every person who has used the copier will experience the problem of paper jam. It should be said that the occasional paper jam is unavoidable in the process of copying, but if the paper is often jammed, it shows that the machine is out of order and needs to be repaired. Factors causing jamA lot of, mainly has following several factors;1. carton cardboard: (1) carton (2) paper rubbed parts2. paper road paperboard: (1) aligning roll; (2) separating mechanism; (3) paper path sensor; (4) separating claw; (5) fixing roller;3. automatic pagination causes jamThe 4. scan component causes jam5. machine short circuit causes jam6. improper handling, resulting in cardboardInspection and maintenance of concrete jam:The L. card in the transmission fault causes and elimination methods in the paper:(1) the paper feed clutch is out of control. Adjust and change the paper feed clutch;(2) there is a foreign matter in the feeder. Foreign body removal;(3) the paper is partial to block cold. Clear the blocked paper;2. cards in reason and elimination method of fault separator:(1) separation, loosening, falling or breaking, or air suction and separation, and insufficient suction force, so that the paper sticks on the drum or enters the cleaning box, and theseparation belt is replaced. Adjust the air quantity and position;(2) the paper goes astray. Trouble out of paper offset.3. causes and troubleshooting of frequently jammed paper cleaner:Some contact with the cleaner copier drum part is provided with a grid, it is made of plastics, and prevent the copy paper into the role of cleaner, normal copy, even if there are cards in this part, the paper is also very easy to remove,But the gate is damaged, the paper will enter the cleaner, tight to remove. The cleaner shall then be removed from the photosensitive drum and removed from the machine as necessary and removed from the cardboard for repair or replacement of the grid bar,Ability to continue.Laser printer maintenance manualThe widespread application of laser printers in enterprises and companies is accompanied by the maintenance problems of printers when they are in trouble. This paper mainly aims at the common faults of EPSON laser printers. Including maintenance essentials, common models of the fault code, specific printer failures, etc., hoping to maintain the laser printer when you help.Quick laser printer maintenance and fault codeLaser printer is a kind of highly automatic computer output equipment integrating light, machine and electricity. It is mainly composed of laser scanning system, mechanical drive system and imaging medium with the toner and cartridge, as well as the circuit part, the conversion part and heating part. Its working principle is the first charging unit inside the machine to the cartridge plus negative charge, then the board according to the laser laser emission from the host signal transmitted over the control, the laser shines on the cartridge surface will leave an electrostatic image in the toner in the toner chamber surface, the toner is adsorbed to the toner image formed on the surface of the electrostatic toner image, when the toner cartridge the surface and send the paper contact image transfer to the paper, by the end of the paper is heated so that the image permanently stored in paper. The printing process can be divided into 7 steps: charging, exposure, imaging, transfer, separation, fixing and cleaning.When a fault occurs, to the exclusion of other improper operation and material is not suitable for the problem, do not rush to the dismantling of printer, first turn off the power switch, such as printer temperature down after a reboot, to observe whether the fault is cleared if the fault phenomenon still into maintenance. Also note that many components of the laser printer, such as the drum assembly, the fixing assembly, and the paper rubbing wheel, are part of the consumer and need to be replaced regularly.Laser printer repair failure: no electricity output, output,cardboard, blank black, pale and output when writing vertical stripes, Liby printing paper, printing paper on the black side repeated dirt1, laser printer preheating more than 2min or amorphous, text fall off.One is to consider whether the indoor temperature above 20 degrees celsius;The two is to check if the thermistor is out of contact or invalid;Three is to see whether the voltage reaches 220V;Four is to see the paper, toner is too dampWet, etc..2, cardboardFirst, check the size of the paper is appropriate, the paper is too thick, too thin, paper wet or volumeSong, will produce jam phenomenon;Two is coated paper can not be used for ordinary laser printers;The three is to check the separation of the laser printer claw is worn, need to change.3, such as printed on the part or all of the word is not clear, toner uneven uneven and so on.The reason for this failure is the amount of toner cartridge is insufficient, need to supplement.4, appear on the print black or underworld, and change paper still appear in the same position.The cause of the malfunction is the damage of the OPC drum.5. If there is a horizontal stripe on the print, it will appear in the same position after changing paper,It shows the need to change the squeegee6. If there is a longitudinal stripe on the print, it will appear in the same position after changing the paper,The magnetic roller on the powder storage box is damaged and needs to be replaced.7, in the printing piece, the big character has the zigzag shape, the writing appears a straight line, lacks the pen to delimit,Note that the six corner mirror or F theta objective has dust to be cleaned(this problem should be dealt with by professional and technical personnel).Note 8, replacement of toner:First, the powder feeding bin and powder storage bin should be cleaned;Two, after the toner, the powder in the toner warehouse parallel shake, clockwise rotation of the teeth by handThe number of rings, so that toner evenly attached to the magnetic roller, to ensure uniform toner.9, if the replacement toner after writing ink irregularity or powder leakage phenomenon, print a few after theBarrier or unresolved, at this time we must first consider whether the wet toner, followed by considering powder deliveryIs the toner in the bin too full?.10, laser printer in the process of hair sample, if the host's monitor appears "laser printer"When the word "power off" and "peripheral equipment is not ready" is mainly connected from the signal lineFind solution.11, if the laser printer self-test, the pattern is all black, no self-test lines. HostThe monitor appears "IACK", which indicates that the videointerface card is out of order.EPSON laser printer maintenance EssentialsFault diagnosis program EPSON laser printer will be built according to different types of machine fault code is displayed in a different way when a fault occurs, the maintenance engineer can estimate the fault code meaning of fault location, refer to the corresponding solution models according to the maintenance manual manual maintenance.EPSON laser printer fault code display is divided into the following 3 types:1. screen display type, its fault code through the printer control panel on the LCD screen display. Representative models are EPL-N1610, EPL-N2120 and so on;The 2. indicator display type, its fault code, is displayed by the indicator light on the printer control panel or different combinations of flashes or lights. Representative models are: EPL-5900, EPL-6100 and so on;3. computer screen display type, when the fault occurs, by pressing the key combination on the keyboard, the fault code will be displayed on the computer screen associated with the printer. Representative models are: EPL-6100L, EPL-1220 and so on.Printer stepping motor maintenanceThe manufacturing accuracy of printer stepping motor is higher, and the main fault is non feed. The following methods can be used to judge whether the motor is damaged or not.(1) measure the resistance according to the resistance value on the step motor. The stepper motor is divided into two winding, two winding structure is the same as that of the other end of each winding center symmetric resistance are equal, and consistent with the marked resistance, different order of different motor wire.When measuring the first use of multimeter will be divided into two groups (each lead wire connected to a group), and then find out the method to measure the resistance center tap end of each group, the center end to the other ends of resistance and resistance value consistent annotation. If the resistance is asymmetric or different from the indicated resistance, the motor may be damaged.(2) test the power supply voltage on the stepper motor (or the working voltage of the motor in the circuit). If the motor is not marked, start using a lower voltage,Then gradually increase the voltage to test. One end of the power supply (both positive and negative) connected to a winding center end, the other end of the power supply at both ends of the winding alternately touching (note the touch time not too long), the step motor step by step rotation, and each step should be equally powerful, or that the motor is damaged. Inspection should be noted that if the stepper motor winding serious short-circuit test must not be, otherwise it will burnout power.(3) some stepper motors have two identical windings, but there is no center tap end. When measuring, you can measure whether the two winding resistance is equal, and should be consistent with the motor tagging, and then use the power supply test. During the test, the power poles are alternately touching each end of each winding. At this point, the stepper motor should be rotated step by step and equally powerful, otherwise the motor will be damaged. It should be pointed out that when the stepper motor is damaged, the stepper motor drive circuit should be checked for damage.。

6.根据复印机复印的颜色不同，复印机可分为单色、多色及彩色复印机三种一、根据复印机工作原理的不同，复印机可分为模拟复印机和数码复印机两种。

1、模拟复印机的工作原理模拟复印机的工作原理是：通过曝光、扫描方式将原稿的光学模拟图像通过光学系统（如：镜头、镜子）直接投射到已被充电的感光鼓上，产生静电潜像，再经过显影、转印、定影等步骤，完成整个复印过程。

2、数码复印机的工作原理首先通过CCD（电荷耦合器件）传感器对通过曝光、扫描产生的原稿的光学模拟图像信号进行光电转换，然后将经过数字技术处理的图像数码信号输入到激光调制器，调制后的激光束对被充电的感光鼓进行扫描，在感光鼓上产生静电潜像，图像处理设备（存储器）对诸如图像模式、放大、图像重迭等作数码处理后，再经过显影、转印、定影等步骤，完成整个复印过程。

数码复印机基本上相当于把扫描仪和激光打印机的功能融合在一起了。

复印机的工作原理主要包括以下三个基本的原理：静电原理电荷有正负两种极性，所谓静电原理是指同性电荷相互排斥；异性电荷相互吸引。

柯美机器装打印卡出56-04
柯美机器装打印卡出56-04是打印卡机号和复印机机号不匹配才出现的代码。只须将正确的机号输进复印机即可。（因为打印卡是另外机器上拆下为的，而非该复印机本身的打印卡）
故障现象:昨天遇到的一问题,共享打印机,打印就最多只能打四张.便觉得很奇怪 ...
PS:以下是从网上搜索到的资料..以供参考...尚待验证.
最佳答案
你office里面的打印设置。。。。页面范围，改成全部。 --------------------一下内容为lz自行解决过程------------困扰我好几天的问题分享一下(只能打印一页)困扰, 打印, 分享上周五发现一个怪异问题，我们公司的打印出现只能打印一页或者打印无反应，报错的问题。我们的打印是通过服务器部署到客户端的，也就是网络共享打印，测试在服务器打印正常，客户端通过端口直接安装也正常。通过排除，打印机没有问题，网络没有问题，不是端口的问题，也不是服务器的问题，客户端也没有问题，这下可难倒我啦，网络上也找不到解决办法，打电话给打印机技术部门也无法解决。后来实在不行，ERP每天打印量很大，打印机没好，就出不了货，老总亲自督促我解决，一怒之下把服务器给重装啦。刚装好发现一切正常，可第二天问题又来啦，顿时崩溃，研究来研究去，肯定是补丁的问题，但那么多补丁，一下子真不知道从哪儿下手。分享：把windows补丁KB971633和KB961371删除就行了，希望对碰到这个问题的有帮助。-----------------------------------------以上。

复印机维修手册全集目录1.基础知识–复印机的工作原理–复印机的分类–复印机的组成部分–复印机的常见故障2.维修工具与设备–常用维修工具介绍–维修设备的选择和使用–安全使用维修工具的注意事项3.维修流程–维修前的准备工作–维修的常见步骤–维修后的测试与验证4.常见故障排除–复印机无法开机–打印质量不佳–纸张卡住或无法进纸–噪音过大或异味–其他常见故障解决方法5.维护与保养–日常维护注意事项–常用耗材的更换与保养–定期维护的步骤与注意事项6.安全与风险防范–维修过程中的安全注意事项–防止电击和火灾的措施–紧急情况处理方法1. 基础知识复印机的工作原理复印机是一种通过光学和电子技术来实现纸质文件的复制的设备。

它的工作原理主要包括以下几个步骤： 1. 扫描原稿：使用光学传感器将原稿的图像分解为光和暗的像素点，生成数字信号。

2. 图像处理：通过电子模块对原稿图像进行处理，包括增强、调整亮度等。

3. 感光鼓充电：使用高压电场将感光鼓表面充电，准备接收图像信息。

4. 曝光：通过激光或闪光灯等光源将扫描得到的数字信号转化为光信号，并照射在感光鼓上。

5. 显影：在感光鼓上涂上感光粉，光信号照射后，感光粉会被吸附在光和暗的像素点上。

6. 转印：感光鼓表面的感光粉转移到纸张上，生成复制品。

7. 定影：通过热或压力将感光粉固定在纸张上。

8. 清洁：清除感光鼓上的残留粉末，准备进行下一轮的复印。

复印机的分类根据使用的技术和原理不同，复印机主要可以分为以下几类： 1. 平板式复印机：将原稿放在平板上，通过扫描原稿和打印的方式来完成复制。

2. 单面扫描复印机：通过单面扫描原稿的方式来完成复制。

3. 双面扫描复印机：通过双面扫描原稿的方式来完成复制，可一次性完成双面复制。

4. 针式复印机：通过针头打印的方式来完成复制。

5. 激光复印机：通过激光和静电原理来完成复制。

分享复印机维修资料（Share copy machine maintenanceinformation）Share copy machine maintenance informationCommon failure analysis of copierFailure 1 failure phenomenon: a ricoh FT - 4495 copier, recently because of toner used up, replace the toner, use soon no powder light is still shining, prompt toner is not enough, main motor idling, can't be photocopied.Failure analysis and troubleshooting: according to the fault phenomenon, it is estimated that the ink cartridge is not installed in place, refill the cartridge, and check the toner amount of the cartridge, and then start the test again, the fault is still. Open the front cover, transmission observation for powder mechanism for powder found turning roller gear drives the driving wheel and the mixed powder gears, that failure occurs in the mixed powder gears in the transmission of the ink cartridges. Take out the ink cartridges, found between the ink cartridges and mixed powder gear meshing gear twist off, causing the ink cartridges, mixing powder inside the roller cannot turn ink cartridges can't for the powder, the machine will not work, get back the original powder, ink cartridges, will back into the original ink cartridges, toner reinstall ink cartridges, troubleshooting.Summary: when replacing the cartridge, you must first gently shake the new box, make the ink powder evenly distributed, and rotate the roller to make it flexible and free of dead points.Otherwise, it will cause the grinding roller meshing gear to break the phenomenon, causing unnecessary loss. The working process of the copierThe working process of photocopiers mainly includes the following parts: (in order of reproduction)Charging components (high voltage generator, electrode holder, motor wire)The surface of the sensitive drum is charged.Exposure component (scanning exposure lamp, reflector, lens)The surface of the light-sensitive drum is based on the original image and the inverted potential image of the image is formed. (the previous chapter has been explained)Developing components (developer, high voltage generator)The potential latent image of the surface of the sensitive drum is transformed into a toner image. (the previous chapter has been explained)Paper parts (motor, paper wheel)The motor drives the paper wheel to transfer the copy paper into the machine to prepare the next step to transfer the toner image of the drum surface to the paper.Transfer parts (high voltage generator, electrode holder,motor wire)By the transfer of the electrode, the surface of the copier paper is evenly distributed with the charge of the opposite of the toner charge, and the ink image on the photosensitive drum is transferred to the copy paper.Separation components (high voltage generator, electrode holder, motor wire)Since the surface of the photocopier paper and thelight-sensitive drum is charged, and the polarity is opposite, the copy paper is not easy to separate from the light-sensitive drum during the photocopying process. Therefore, it is necessary to take separate measures to separate the photocopying paper from the drum. Earlier copiers were mechanically separated, but easy to paper; Current photocopiers are separated by current. The separation current contains high frequency ac and fixed dc components.Cleaning parts (cleaner)Clean the residual toner powder on the surface of the sensitive drum and prepare for the next photocopy. It is impossible for all copiers to transfer the ink from the surface of the sensitive drum to the copy paper by transfer. Therefore, the surface of the drum has residual toner, not cleaning, which will affect the quality of the reproduction.Fixing parts (fixing heat rod, pressure rod, heater)The toner image on the copy paper is fixed on the copy paper.In order to preserve. If the image is not fixed, the image on the copy paper will fall off. (so the fixing requires certain temperature and pressure)The process of photocopiers also includes many auxiliary processes, mainly including:Electrical components (full exposure lamp)Remove residual potential from the surface of the sensitive drum and prepare for subsequent photocopying. Otherwise the copy will have residual images or ashes.Remove edge parts (such as side-down lights)The photocopy has a front end, front and back end, or a reduced part of the blank. Therefore, it is necessary to remove the surface potential of the light-sensitive drum which is not required by the electric light bulb.The daily use of copierDigital duplicator, composite machine in small andmedium-sized enterprise office, is often used to, and sometimes need to purchase machine or buy consumables, etc., these are our procurement staff a problem, how to choose the suitable machine company, how to buy authentic materials, and so on. Today, the author gives you a comprehensive and comprehensive information, with daily use skills, and some expert views onhow to purchase consumables and machines. I hope I can help you in your daily work.Troubleshooting and troubleshooting of photocopiersThe copier is accidentally jammed with paper, not broken, but if it is frequently jammed, it needs to be checked and repaired. First of all, should make clear which part of the paper, is for the paper part, the paper part, or the fixing part? Of course, if there are any obvious damage to the three parts, it can be replaced. But in many cases, the whole transmission mechanism has no obvious damage to any parts and no obstacles, but it is frequently jammed, affecting both work efficiency and operating emotions. For maintenance personnel, sometimes several factors are intertwined, affecting the diagnosis.The photocopier1. For the paper parts of the paper: paper jam at this site, which involves many aspects, should first check the paper up to standard, such as paper, weight, size, drying degree), ma chine to use standard paper. The paper box is not the rule, it is also the cause of the paper. It can be tried in this way, only put a few pieces of paper in the carton, and then take the paper. If it is not in or out of the paper, it can be judged to be the problem of rubbing paper wheel or rubbing paper clutch. If the paper is in place, but the paper cannot continue to advance, it is estimated that it is caused by the failure of the roller slip or the counterpoint clutch. For some models, the rubbing paper appears skewed, which may be caused by the difference between the clamping force on both sides of thecarton. In addition, a lot of operators in the box, too hard, causing the paper box to pull the paper out of the claw, also must cause the card paper.: 2. Paper feed part paper, such as in this site often have a paper jam, should with the aid of the door switch plate (a vehicle), observe the workings of the parts, the ruled out direct, conveyor belt is round, should check the separation mechanism. Because of different types of copiers, they are separated in different ways and should be treated differently. At present, several types of domestic popular models are divided into three kinds: negative pressure separation, separation band separation and charge separation. Specific inspection, maintenance methods, no longer detailed here.3. Card paper of the fixing part: when the fixing roller has been used for a long time,The cutting edge of the blunt or small spring fatigue can result in the paper. For some models, the long time to use the paper roll of the paper roller is used for serious wear, and the paper will be jammed frequently. As for the fixing roll of serious fouling, the paper, on the general model is a common situation.How to buy a photocopier for firm consumptionNowadays to buy copiers don't pay attention to the price, some of the irregular copier dealers, in order to earn more profits, unexpectedly the machine modification or replacement of false consumables, such not only affects the use fixed number of year of copy machine, also can increase the failure rate of thecopier. Here are a few things to note about buying copiers:The first is whether the copier is open and the original machine is a single seal.The ink cartridges of the second original photocopier are packed in zinc and packed neatly.Third, the photocopier of fake toner, the effect of black and white is much worse than that of ordinary photocopier.In the use of the fourth fake toner, there will be a special odor.The number of photocopying of the fifth copier is not the same as the technical parameters, which is not easy for customers to notice, and also the most important way to identify.Buying a photocopier is one of the few things to pay attention toThere are many kinds of photocopier market brands, and there are many functions. What kind of copier should a small and medium sized enterprise choose?This should be seen from several angles: first, according to the usage of customers, it is divided into low, medium and high-speed photocopier. The load capacity of each month is different, usually 10,000 CARDS to choose the low speed machine;2 -- 50,000 selected medium-speed copiers, even if the user is large enough to meet the needs. 5-10 pieces must be bought athigh speed. Second, the function of choosing a copy machine must see that the function of the photocopier can be satisfied with your use, such as now can be added, printing, scanning, facsimile and other functions. The average life of a photocopier is between five and eight years, and it is also important to consider whether it can be met, or at the provincial level, at a later time. Third, does the consumables of the photocopier make you happy? Some photocopiers are cheap to use on machines, but the cost of later use is simply amazing, which is generally based on the actual usage of the customer.About after-sales service on this a few big brands are about the same, Canon, sharp, ricoh, Toshiba is one year free service, but the kyocera copiers is three years free on-site maintenance, so, again, ask when buying a copier copier maintenance time.Reset method of special fault code for sharp copierSharp 700/800 series duplicator special fault code mainly include HX (H1 H8, hot roll fixing device failure), Lx (L1 - L6, micro switch/photoelectric switch failure), Ux (U1U2, low battery voltage or data transmission failure) and Pl (exposure lamp temperature fuse exception). Among them, the U1 with instruction "13" reset, other special fault code "14" reset with instructions.The special fault code of sharp 1000/2000 series copier is mainly HX (h2-h4, hot roller fixator failure) and U2 (memory literacy failure).Other special fault codes are reset by instruction "14".The special fault code of sharp 7000/8000 series copier mainly has HX (H3, H4, hot roller fixator failure) and U1 (battery power down). U1 USES instruction "13", reset, H3 H4 to reset the "14". The sequence of reset operation is shown in the attached figureIn addition, the sharp type z60 copier special fault code with U (motherboard battery low voltage), L (micro switch failure), H (hot roll fixing device failure), F (fixing light or temperature fuse problem), said in a "1" reset instruction. When reset, press clear key, repeat key, (add number key), (minus key) digital key "1" and copy key.(1) the key should be pressed in 5 seconds:(2) sharp 750, 770, 771, 780, 781, 825 etc.(3) when all the display on the operating panel disappears, the main motor stops rotating, and the copy machine is ready to accept the instruction (the main motor turns and copiesThe machine does not accept instructions);(4) sharp 1000/2000 series copiers include sharp 1016, 1020, 1025, 1116, 2014, 2020, 2022, 2027, 2040, 2114, 2214, etc. The sharp 7000/8000 series copier includes sharp 7320, 7370, 7700, 7750, 7800, 7850, 8570, 8870, etc.Inspection and maintenance of machine card failureBelieve that each person used photocopiers will have paper jam this trouble, it should be said that in the process of copying accidentally paperboard is inevitable, but if a paper jam, often is the malfunction with the machine, need to repair. The factor that causes the card paperMany, mainly include the following factors;1. Carton card: (1) paper box (2) rubbing paper parts2. Paper card paper: (1) counter roll; (2) separation mechanism;(3) paper road sensor; (4) separating claw; (5) the upper fuser roller3. Automatic pager causes the card paper4. The scanning part caused the card paper5. The internal short circuit caused the card paper6. Improper operation caused the paperInspection and maintenance of specific card failure:L. Reasons and exclusions for failure of paper card in the paper channel:(1) the paper clutch is out of control. Adjustment and replacement of paper clutch;(2) there is foreign body in the paper channel. Remove foreignobjects;(3) the paper is blocking the cold. Remove the card paper;2. Reasons and exclusions of paper CARDS at the separator:(1) separation belt loose, drop, break, or air suction separation, insufficient suction paper, make the paper stick on the drum or into the clean box; Remove the belt. Adjust the air intake and air position;(2) paper deviation. Troubleshoot paper deviation.3. Reasons and exclusions for frequent card failure of cleaner:Some copier cleaner parts in contact with the photosensitive drum is equipped with a grating, it made from plastic, function and prevent copy paper into the cleaner, normal copy, even if there is paper card in this part, the paper is also easy to take out,But when the grille is damaged, the paper goes into the cleaner, which is hard to take out. When necessary, remove the cleaner from the machine, remove the card and repair or replace the grid.It just keeps going.Laser printer maintenance manualLaser printers, the company is widely used in enterprises, itfollowed the printer when encountering the maintenance problems, and this article is mainly on the common faults of the epson laser printer list. Including maintenance essentials, common machine failure codes, specific printer failures, etc.I hope to be able to help you to repair laser printers.Laser printer maintenance and troubleshooting codeThe laser printer is a highly automated and highly automated computer output device. It is mainly composed of laser scanning system, mechanical transmission system and toner and toner, as well as part of circuit, part and heating parts. Its working principle is the first machine in the charging unit to the drum unit with negative charge, and then the mainboard according to coming from host transmits the signal control of laser laser, laser shines on the drum surface will be left in selenium drum surface electrostatic images, the carbon powder storehouse powder will be adsorbed to the surface of the drum unit electrostatic toner image is formed on the image, when the drum surface and sent the paper to contact image transfer to the paper, finally through the paper heating forever the image on the paper. The printing process can be divided into charging, exposure, imaging, transfer, separation, fixing and cleaning 7 steps.When printer malfunction, must first rule out other improper operation and material is not suitable for the problem, do not be eager to disassemble printer, shut off the main power switch, such as temperature drop down after restart the printer, to see if fault can be cleared, if malfunction phenomenon still for maintenance. It is also important to note that many parts ofthe laser printer, such as the cartridges, the fixing components, and the rolling paper wheel are the consumable parts, which need to be replaced regularly.Laser printer maintenance maintenance fault: no electricity, paperboard, output gap, output black, handwriting slants thin, erect white stripes, the output of the printing paper on unilateral black, repeated dirty mark on the paper1. The laser printer is preheated over 2min or in a fixed shape, and the text falls off.Whether one is considering indoor temperature 20 ℃ above;The second is to check whether the thermistor has any bad contact or failure;The third is to see if the voltage reaches 220V;Four is to see paper, toner is too dampWet, etc.2, paperboard,One is to check whether the paper is suitable, the paper is too thick, too thin, the paper is wet or rolledThe paper will produce the card phenomenon.Second, the paper cannot be used for ordinary laser printers;The third is to check if the separation of the laser printer is needed.3. If local or full characters appear on the printed parts, ink powder is not uniform.The reason for this failure is that the powder cartridge is insufficient and needs to be replenished.4. Black dots or black lines appear on the print, and they appear in the same position after changing the paper.The fault is caused by the damage of the OPC.5. If horizontal stripes appear on the print parts, and they appear in the same position after changing the paper,The need to replace the scraper plate6. If the vertical stripe appears on the printed piece, it will appear in the same position after changing the paper.The magnetic roller on the powder bin is damaged and needs to be replaced.Then gradually increase the voltage to the test. One end of the power supply (both positive and negative) to the center of a winding end, on the other side of the power to touch the other ends of the winding alternately (note the touch time shoulds not be too long), turn the stepper motor should be step by step,and each step should be the same strong, otherwise the motor is damaged. The test should be noted that if the stepping motor winding has a serious short circuit, do not test, otherwise it will burn the power supply.(3) some stepper motor has two identical windings, but no central tap end. When measuring, the resistance of the two windings can be measured first, and should be consistent with the motor mark, and then the power test will be used. In the experiment, the two ends of each winding are touched by the two poles of the power supply, and the stepping motor should be moved by step by step, and the motor will be damaged. It should be noted that when the stepping motor is damaged, it should check whether the driving circuit of the stepping motor is damaged.。

，但送稿器上的原稿仍没有停，也在扫描，这时复印出来的复印品也会全白。

这种情况就检查扫描架道轨是否有异物卡住。

如果没有可能是CCD坏了，需更换掉。

关于AR-161/200易出F5、F1-06、U2-40维修方法一、F5的解决方法AR-161/200出现F5一般为光学部分脏污，首先取下稿台玻璃，将反光镜和曝光灯清洁干净，如果标尺下的白板脏污，也同时清洁干净，盖上稿台玻璃应该就不会再出现F5了，出现这种情况在平常不使用机器时用布将机器罩住，但清洁后仍然出现就更换CCD组件试试。

二、F1-06解决方法出现F1-06一般为分隔板电机部分出现异常，引起开机对隔离板上下不到位，出现异响把机器分页器电机取下，调整电机上的原位传感器，调整完后上可能应该没有问题了，但要记住上还原后，将分离电机移动杆位置是否正常，如不在原位就会引起卡纸故障。

三、U2-40故障解决方法一般是由于粉盒上的芯片故障，如有可能是机器在检测粉盒时出错，用SP-16消除就好了，如果无法消除，就换一盒新粉，问题就自然解决了。

在安装粉盒的时候一定要按说明将粉搅匀。

AR275双面复印卡纸解决方案对应机型：AR275、AR255、ARM276 故障现象：由于用户频繁使用双面复印，故造成复印机双面复印时卡纸。

解决方案一：在最近的维修工作中，经常遇到夏普AR275系列档次的机器出现双面复印卡纸的问题。

具体问题是机器复印效果正常，且进行单面复印时无任何严重的卡纸现象。

只要进行双面复印，或几张或几十张过后，必定出现轻微打齿轮的声响，而后机器卡纸，无法使用。

首先，拆卸机器后盖，进行双面复印观察，发现机器出纸部分随纸张的来回运动而左右摆动，因此给机器出纸部分安装了一个铁支架加以固定，出纸部分摆动状况减弱但仍要出现双面卡纸。

而后又发现连接出纸部分与定影部分驱动的一块带有三个齿轮轴的双面驱动板有变形，三个齿轮轴有轻度的不平行，故更换后机器可正常使用。

但一个月后用户又反映双面卡纸。

换针方法首先用打印头故障测试程序检查出哪几号针出现故障然后取下色带盒翻开打印头锁定夹从两边捏住打印头散热片即外壳向上提起打印头可以看到连着两根柔性扁平电缆拔去电缆便可拿出打印头用酒精棉球擦洗打印头前面的墨污查看一下是否有缺针情况若是断针则需要进行换针换针时要准备好工具主要有镊子刀片金刚挫钢尺油石和打印头专用夹具一种专门用于拆卸打印头散热片的工具用专用夹具退下散热片可以看到好几层结构将头部朝下松开定位爪取下最上面的后铜盖便可以看到环形分布的12根长针从测试结果区分出断针是长针还是短针然后数出所断长针的位置用镊子取出放在一边如果还有短针断针则继续取出所有长针再用刀片沿中间的黄色铜垫片下方分开露出12根短针用同样方法取出断针继而取下一根好针取长针或短针视所换断针而定用钢尺精确测量该针的长度将新针按所量的尺寸用金钢挫磨好注意将针的头部毛刺磨去后再从原位置插入换好后用手指轻压12根针的尾部使针头从前面探出此时应看到1号针和24号针位有针露出而且各列针与针之间应间隔一孔若有位置插错必须重新调整同时当手指放开后各针都能立即收针保证各针出针畅通只有在确认短针全部到位后才可以安装长针在合上铜座之前还要使每针的定位销入槽将长针层定位孔合上检查没有缝隙便可安装长针了长针只须照着对应孔位置插下去长针自尾部到探出头要经过几道导向槽最上边的槽孔是很容易穿下去的第二道孔稍微难一些只要穿过去针就能顺势而下很容易到达所在位置用拇指压住衔铁针应露出1mm表示换上去的针是好的全部插好后压上后铜盖应无缝隙装好三脚定位爪套上散热片即可上机打印测试 2．打印针线圈故障由于打印头出针动作是依赖于打印针驱动线圈通电后产生磁场吸合或释放衔铁而控制打印针的进退若针驱动线圈烧断开路则相应的打印针就不出针因而造成打印缺点少划若针驱动线圈短路击穿有可能会使整个打印机不工作打印针驱动线圈正常与否一般用万用表的R×1挡测量其直流电阻的方法进行鉴别几种常用打印机的打印头针驱动线圈的直流电阻值参见表1下面以LQ1600K打印机为例为大家介绍一下更换线圈的方法更换线圈时应按照固定的线圈对应关系如图 4 找到坏线圈用小刀切断粘结在线圈架上的明胶再用镊子和电烙铁取出线圈拆下坏线圈时要注意不要将相邻的好线圈碰坏装线圈时应注意线圈的引脚不要和铁壳相碰最后用明胶固定好线圈打印头修好后按照拆卸时的逆顺序将打印头恢复打印针和线圈维修完后先不要急于开机如果打印头中有线圈损坏则需要检查打印机内的驱动三极管V1-V24是否正常24个驱动三极管的外围电路完全一样所以在正常情况下测每只三极管的静态在线参数是很接近的在打印机断电的情况下用万用表测量各驱动管的b-ec-e之间的电阻就能判断驱动管是否有问题如果驱动管中有损坏仍会烧坏驱动线圈

爱普生7725维修手册

爱普生7725维修手册主要原因分析：打印机所处的环境温度过低：冬季寒冷干燥，打印机工作在干燥和温度比较低的环境中，会使打印机字车导轨上的润滑油的润滑效果减弱，字车在导轨上移动时摩擦阻力增大，易出现打印头撞击的现象；灰尘过多：冬季风沙较大，过多的尘土落入打印机，导致字车在导轨上摩擦阻力增大，出现打印头撞击的现象；打印机内部有异物：特别是对于新购买的打印机，用户对打印机不是很了解，包装材料没有完全被去除掉，最容易出现这种现象。

解决办法：打印机工作的环境温度和湿度保持在：温度在10-35℃之间；湿度：20～80% (相对)清除打印机内部异物：对于新购买的机器请一定按《用户手册》的要求去除保护材料。

当打印机卡纸时，请严格按《用户手册》的要求清除卡纸。

爱普生7725喷墨打印机如何区分堵头与断线使用爱普生7725喷墨打印机时，应养成经常做喷嘴检查的习惯，尤其对于不天天使用的用户，可避免因为断线引起的打印稿报废，免得无谓的时间和墨水浪费。

爱普生7725打印机喷嘴检查所打的斜条图案中的每一条小横线代表一个喷嘴，当有缺线时，好些人以为是堵头了。

其实绝大部分情况仅仅是发生断线，产生断线的原因很多，如换墨盒、加墨水、长期不用等等，通常能通过做"打印头清洗"即可解决。

如何判断是堵头了还是断线：若每次清洗后，图案中缺线位置没有变化，总是在固定的位置缺线，表明是该喷嘴堵住了。

若缺线的位置是变化的，则不是堵头而是断线。

在更换墨盒时（或加墨水后）有断线是正常的。

一般清洗一、二次全好，而且是每次清洗断线都会减少（注意：两次清洗时间最好间隔20分钟以上）。

使用中出现断线，如果越清洗断线越多，则是墨盒中的墨水没有了，这是应立即更换墨盒或填充墨水。

柯美7272、7155、7165、HP9055、9065复印机漏粉解决办法-绝对管用

柯美7272、7155、7165、HP9055、9065复印机漏粉解决办法-绝对管用漏粉的话，最大的嫌疑就是粉不好，现在就推荐两种粉：都是袋装的，一种是黄色的包装的，就是下边有个脚，打开就可以立起来的，这种粉广州很多人做，还有一种就是银白色包装的，上面贴的牌子是米蓝（米兰），不晓得谁做的。

那种黄色包装的确实很给力，不漏粉，没异味，而且浓度很黑，如果漏的是载体的话，用手一摸，会有沙粒的感觉，是充电架上边飘粉导致充电架漏电，就会导致漏载体，载体老化了也会导致漏粉的。

其实只要粉好一点，调不调下粉量都无关紧要，但是还是给出以下几种下粉量调法仅供参考。

这个是标准，出厂设置都是这样：, 05-0-关闭0,05-1-关闭0,05-2-开启1,05-3-关闭0， ,23-2-关闭0,23-3关闭0. 下粉量小一点：05-0-关闭0,05-1-开启1,05-2-开启1,05-3-关闭0，23-2-关闭0,23-3开启1.（这样调法，只要碳粉不是太垃圾的话，基本可以用）这个也可以尝试下，：05-0-开启1,05-1-开启1,05-2-开启1,05-3-关闭0，23-2-关闭0,23-3关闭0.参考：05-0-开启1,05-1-开启1,05-2-开启1,05-3-关闭0，23-2-关闭0,23-3开启1.（这个如果鼓架传感器脏的话，可能会不下粉）当然，不管下粉量怎么个调法，前提都是要保证鼓架传感器的清洁，载体没有老化。

只要碳粉好，基本上你调个标准就可以高枕无忧啦。

声明：有错误的地方在所难免，请纠正5-0，5-1，5-2，5-3调成0，0，1，0，23-2，23-3调成1，1；为什么还是漏粉了，回收杆都已经拆了，用瓶子装废粉，还是漏粉啊，下粉电机就是做死的转，不知道是什么原因?造成漏粉的主要原因有三个方面：一、粉的质量，二、废粉回收不畅，三、供粉量太大如果同样的粉在别的机器上没这种现象，那就排除了粉的质量这一问题；那就看回收粉的系统是否顺畅，比方说后面那个白色离合器一样的会不会太紧？把它清洁一下，那跟鼓靠在一起的那软辊会不会太硬了？用久了会变硬的，粉有没有在弹簧里或管子里成硬块？如果这些都清洁和排除过了还掉粉，那很能是供粉量太大了。
