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.。

第一章复印机的工作原理一、复印机的种类1.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。

2.根据复印的速度不同,复印机可分为低速、中速和高速三种(每分钟复印A4幅面的张数来决定)。

复印机每分钟可复印A4幅面的文件10-30份,中速复印机每分钟可复印30-60份,高速复印机每分钟可复印60份以上。

3.根据复印的幅面不同,复印机可分为普及型和工程复印机两种。

一般我们在普通的办公场所看到的复印机均为普及型,也就是复印的幅面大小为A3-A5。

如果需要复印更大幅面的文档(如:工程图纸等),则需使用工程复印机进行复印机,这些工程复印机复印的幅面大小为A2-A0,甚至更大,不过其价格也非常昂贵。

4.根据复印机使用纸张,复印机可分为特殊纸复印机及普通纸复印机。

特殊纸一般指可感光的感光纸,而普通纸是指普遍使用的复印机。

5.根据复印机显影方式不同,复印机可分为单组份和双组份两种。

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。

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.。

针式打印机主板的芯片级维修资料

针式打印机主板的芯片级维修资料
针式打印机主板的芯片级维修资料
一般主板导致的问题有这些:有电和没有电
1.有电情况:不联机.乱码.字车问题.走纸问题.缺针.多针.灯闪无反应(正常闪)灯闪无反应(不正常闪)
当一块针式打印机主板在你面前时,首先是测试5V电路与地线的阻值。

是否短路。

还有高压(36-42)V。

电路短路了你还测试就会很严重了。

重着烧主板。

打印头(打字头),轻着没事。

讲到这里又要说怎么找5V低压和高压了,一般主板都有标识没有的话看电源的5V 到主板线路了。

在就是观察表面有没有物理损伤,也是比较重要的,有的芯片表面有个洞,线路断了.......等等。

不联机.乱码:从接口电路到(门正)主芯片的电容,电阻,接口电路,及主芯片(门正),还有一个那就是字库了。

(次芯片(CPU))
字车问题:从字车驱动到门正的电路了,也要注意线路,电容,电阻,这些和门正芯片了。

走纸问题:从走纸驱动到门正的电路了,也要注意线路,电容,电阻,这些和门正芯片了。

缺针.多针:从针驱动到门正的电路了,也要注意线路,电容,电阻,这些和门正芯片了。

灯闪的问题就比较麻烦了,还是得一步步来,CPU到字库的电路会造成这些问题,门正,CPU.......
这些原理适用于所有的针式打印机的原理。

Epson.映美.得实.star.PR2.PR2E联想........................ 经验是非常重要的
2.没有电的情况:。

,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。

数码复印机电源故障芯片级维修一例

办公自动化杂志一、故障现象一台佳能iR2120S 数码复印机断续供电,面板显示时有时无。

二、分析与检修佳能iR2120S 是一款经济型的数码复印机,具有打印、扫描、复印、大容量存储等诸多功能于一体,而且因为运行费用低,在国内低端市场的占有率很高,特别适合于SOHO 一族使用。

一般说来,作为一种机电一体化多功能办公设备,数码复印机与微型计算机的部分功能相似,它也支持远程开机和睡眠唤醒功能,这就意味着它的直流电源分为两大部分:一部分是待机电源;一部分是受控电源。

待机电源主要用于对处理器和存储设备供电,容量较小;受控电源则是复印机正常工作时的供电电源。

它主要为功率部件(如电动机等)提供电流,容量较大。

受控电源是否工作受来自主板的逻辑信号控制,信号为高电平时,受控电源关闭,系统处于低功耗的休眠状态。

如果信号为低电平时,受控电源开始工作,系统唤醒,正常工作。

针对出现的故障,首先检查复印机的市电供电电源,在确认了供电没有问题后,打开机壳,取出电源板,测量电源板的输出。

经测量,J10的4、5端子之间有3.3V 电压,9、10端子间有5V 电压,而且很稳定。

这说明机器内的开关电源已经开始工作。

接下来的工作是对电源板电路作进一步研究。

图1直流电源二次侧电气原理图(局部)图1是根据实物绘制整理出的直流电源二次侧的电气原理图,T101是高频变压器,图中仅画出了其二次侧绕组。

整个电源电路分成三个部分:待机电源、控制电路和受控电源三个部分。

整个电源以V+作为主输出,以V+的电数码复印机电源故障芯片级维修一例曲延昌(山东工业职业学院电气工程系淄博255046)摘要:简单介绍了数码复印机这种设备电源工作的基本逻辑,基于根据实物绘制出的电气原理图,分析了有关电路的基本工作原理,给出了一种芯片级故障维修的思路。

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。

复印机的组成部分一台复印机通常由以下几个主要部件组成: 1. 控制系统:负责控制复印机的工作流程和各个部件的协调工作。

故障原因与排除方法: 复印机的搓纸轮大多数靠电磁线圈的动作来控制。检查时需使机器处于有纸状态,可用 透明胶纸将检测有无纸盒的开关粘住,使无纸信号不出现,将一小块纸放在检测纸盒的光电 传感器上,按下开始复印键后,大约 1 ̄2 秒钟后,控制搓纸轮的电磁线圈的衔铁应有吸台动 作,如果无此动作,则应检查电磁线圈与线路板间的连线接触是否良好。如果有此动作,则 应考虑搓纸离合器内的弹簧是否损坏;生锈,必要时应更换离合器。
鼓。 (5) 墨粉颗粒太大,显影图像表面粗糙,造成分辨率下降。如出现由于图像发黑而造
成不清 晰,应考虑可能是显影器下墨粉太多。
13. 复印件图像浓度不均匀 复印件复印出的图像不均匀分两种情况:一种是有规则的不均匀;另一种是无规则的
不均匀。 (1) 出现有规则的不均匀故障原因与排除方法: ① 电极丝与感光鼓不平行,造成转印电晕不均匀。 ② 曝光窄缝两边不平行,造成曝光量不均匀。 ③ 机内有乱反射光的干扰。 ④ 显影辊与感光鼓表面不平行;液干法显影中挤料辊与感光鼓不平行;显影间隙两
端不等, 均会造成上述的不均匀。
(2) 出现无规则的不均匀故障原因与排除方法: ① 复印纸局部受潮。 ② 曝光灯管、稿台玻璃等光学部件受污染,影响光反射和透射的均匀。 ③ 充电和转印电极丝污染,造成放电的不均匀。为防止此种情况,应经常保持电极
清洁使放 电均匀。 ④ 采用热辊定影的机器,由于加热辊表面橡胶老化脱落、有划痕,或定影清洁刮板
4. 复印后复印件出现底灰 复印件上有深度不等的底灰,是静电复印机中一种常见的现象,而且是一个难于解决的
问题,复印件上有无底灰存在是鉴别其质量好坏的重要标志之一。 故障原因及排除方法: (1) 曝光不足,原因包括曝光灯老化,照度下降;光蓬开得太小,曝光量小。调整曝光
电压、光缝或更换曝光灯; (2) 原稿反差太小; (3) 复印纸受潮; (4) 显影偏压过低或无显影偏压;调整显影偏压、检修显影偏压电路。 (5) 第二供纸行程开关是否良好,位置是否合适,有否积粉脏污; (6) 第二供纸离合器是否良好; (7) 扫描台行程开关中的对位起始微动开关或传感器是否失效; (8) 纸路当中是否脏污、有异物等。
4.2 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。
本节中所列举的故障,对于各种复印机并非一律如此,即使同一故障在不同的类型的机 器中,其成因可能并不相同。因此,这里更重要的是提供方法和思路。(有些故障只要找到 成因即知排除方法,因此这些故障的排除方法就不再赘述。)
⑨ 复印绿键按下后,第一步供纸不良 故障原因及排除方法: 首先观察搓纸是否转?如果转动良好而不能搓纸,则检查:
a. 搓纸轮是否脏污、老化、摩擦力下降,如果脏污,可用浓酒精擦洗;如果磨秃老化, 可更
换新搓纸轮。也可采用土办法:剪一段橡胶指套,套在搓纸轮上,实践证明,这是解 决搓纸轮摩擦力的有效方法。 b. 顶纸板弹簧顶力是否下降,如果下降,就进行调整。
