EPSON打印机的使用及维修经验

EPSON打印机的使用及维修经验EPSON, 打印机, 经验, 维修《EPSON打印机的使用及维修经验一》在国内的各单位中，EPSON是目前仍在普遍使用的主力打印机，该系列打印机的使用及维修仍是我们必须关注的问题。

笔者在此根据个人及朋友的经验，向大家介绍一些使用及维修的见解，希望能对大家有所帮助。

(一).使用时应注意的事项1.确保使用环境清洁。

使用环境灰尘太多，容易导致字车导轴润滑不好，使打印头的运动受阻，引起打印位置不准确或撞击机械框架造成死机。

有时，这种死机因打印头未回到初始位置，在重新开机时，打印机首先让打印头回到初始位置，接着将进行清洗打印头操作，所以造成墨水不必要的浪费。

解决这个问题的方法是经常将导轴上的灰尘擦掉，并对导轴进行润滑 (选用流动性较好的润滑油，如缝纫机油)。

2.墨盒未使用完时，最好不要取下，以免造成墨水浪费或打印机对墨水的计量失误。

3.关机前，让打印头回到初始位置 (打印机在暂停状态下，打印头自动回到初始位置) 。

有些打印机(如StyluScolor、StylusProXL、MJ－1500K等)在关机前自动将打印头移到初始位置；有些打印机(如MJ－800K、Stylus－1000、StyluScolorⅡ等) 必须在关机前确认处在暂停状态(即“暂停灯”或“Pause”灯亮) 才可关机。

这样做，一是避免下次开机时打印机重新进行清洗打印头操作，浪费墨水；二是因为打印头在初始位置可受到保护罩的密封，使喷头不易堵塞。

4.部分打印机在初始位置时处于机械锁定。

此时如果用手移动打印头，将不能使之离开初始位置。

注意不要强行用力移动打印头，否则将造成打印机机械部分的损坏。

对于像MJ－1500K、 StyluScolor等打印机，在初始位置时打印头处于锁定状态，此时更不要人为移动打印头来更换墨盒，以免引起故障。

5.换墨盒时一定要按照操作手册中的步骤进行，特别注意要在电源打开的状态下进行上述操作。

解决方法：1. 更换墨盒或碳粉；2. 清洁打印头或喷嘴；3. 更换高质量的打印纸。

1.2 斑点或条纹斑点或条纹是指打印结果中出现黑色或彩色小点或线条。

此问题可能由以下原因引起：- 墨盒或碳粉表面有污染物，需清洁墨盒或碳粉；- 打印头或喷嘴堵塞，需清洁打印头或喷嘴；- 墨盒已接近枯竭，需更换墨盒。

解决方法：1. 清洁墨盒或碳粉；2. 清洁打印头或喷嘴；3. 更换墨盒。

2. 纸张进纸问题2.1 多张纸一同进纸多张纸一同进纸是指打印机在进行打印任务时，同时将多张纸张送入打印机。

此问题可能由以下原因引起：- 打印纸张质量不好，需更换高质量的打印纸；- 打印机进纸辊损坏，需更换进纸辊。

解决方法：1. 更换高质量的打印纸；2. 更换进纸辊。

2.2 纸张卡纸纸张卡纸是指打印过程中出现纸张无法正常进纸或进纸困难的情况。

此问题可能由以下原因引起：- 打印纸张放置不正确，需重新调整纸张位置；- 打印纸张质量问题或过于湿润，需更换高质量且干燥的打印纸；- 打印机进纸辊损坏，需更换进纸辊。

解决方法：1. 调整纸张位置，确保放置正确；2. 更换高质量且干燥的打印纸；3. 更换进纸辊。

三、常见故障预防与维护1. 定期清洁打印头或喷嘴定期清洁打印头或喷嘴可以避免堵塞问题的发生，保证打印质量。

可通过打印机自带的清洁程序进行操作，或者使用洗涤液轻轻擦拭打印头或喷嘴。

If inkgets in your eye, flush the eye with fresh water and see a doctorimmediately.Always wear gloves for disassembly and reassembly to avoidiujury from sharp metal edges.To protect sensitive microprocessors and circuitry, usestatic discharge equipment, such as anti-static wrist straps,when accessing internal components.Never touch the ink or wasted ink with bare hands. If inkcomes into contact with your skin, wash it off with soap andwater immediately. If irritation occurs, contact a physician. WARNING Avant de commencer, assure vous que l’imprimante soit eteinte et que le cordon d’alimentatio n soit debranche.Veillez a jeter les piles usagees selon le reglement local.CAUTION Risque d’explosion si la pile est remplacée incorrectment. Neremplacer que par une pile du même type ou d’un type équivalentrecommandé par le fabricant. Eliminer les piles déchargées selonles lois et les règles de sécurité en vigueur.When transporting the printer after installing the ink cartridge, CAUTIONbe sure to pack the printer for transportation without removingthe ink cartridge.Use only recommended tools for disassembling, assembling oradjusting the printer.Observe the specified torque when tightening screws.Apply lubricants and adhesives as specified. (See Chapter 3for details.)Make the specified adjustments when you disassemble theprinter.(See Chapter 5 for details.)Make sure the tip of the waste ink tube is located at correctposition when reassembling the waste ink tube. Otherwise itwill cause ink leakage.1.1.2 ToolsUse only specified tools to avoid damaging of the printer.Table 1-1.

Not necessary1.2Caution regarding assembling/disassemblingof the printer mechanism, and how toensure of quality on re-assembled productOn current low end models, we basically forbided to remove Housing (Lower) from Printer mechanism in your repair. This is because there is a possibility of main frame deformation when a part (such as Ink system) is removed from Printer mechanism without Housing (Lower).Therefore, if you want to replace Ink system/PF motor, we recommend to replace with new Printer mechanism with Housing (Lower).On these models, you have to remove Housing (Lower) from printer mechanism when replacing [Porous Pad] with new one.Therefore, we clarify caution regarding assembling/disassembling of the printer mechanism without Housing (Lower), and how to ensure of quality on repaired productsin this section.[Caution regarding assembling/disassembling of the printer mechanism]1)Main frame(a)Control of assembled standard position.[Reason]The assembed accuracy of each part composed of Printer mechanismis based on Housing (Lower).[Service treatment]Confirm that there is no gap between main frame and Housing (Lower).[Reference]To ensure the assembled accuracy, you have to control the assembledstandard position of main frame against X/Y/Z-axis direction. [X-axis direction]-Make sure that main frame is correctly placed on the groove ofHousing (Lower).-Make sure that there is no gap between main frame and Housing (Lower).[Y-axis direction]Make sure that cut-out portion of main frame is correctly placed on thesquare protrusion of Housing (Lower).[Z-axis direction]-Make sure that there is no gap between main frame and Housing (Lower).-Make sure that the left side of Printer mechanism is correctly fixed bytwo hooks.(b)Control of vertical level of guide rail (Guide rail means the portion latchedby hooks of IC holder & Print head assy..)[Reason]There is a possibility that printing failre/operation failure occurs by guiderail deformation.[Service treatment]-Do not remove [Mounting Plate, M/B] from Printer mechanism.-Hold up the specified position of main frame to avoid the deformation.(c)How to assemble of ASF unit/Circuit board/Paper guide upper[Reason]There is a possibility that main frame deformation is caused extra forcein assembling. As the result, printing failre/operation failure occurs.[Service treatment]Hold the opposite side by by hand while you are installing the above parts.2)Front frame(a)Control of vertical level[Reason]There is a possibility that printing failre occurs by front frame deformation.[Service treatment]Handle Front frame in assembling/disassembling carefully.3)IC holder(a)Handling of IC holder[Reason]If IC holder is damaged in assembling/disassembling of your repair, there isa possibility that vital problem occus in user’s futher operation.[Service treatment]Released two hooks of IC holder from the inside of IC holder by the tweezer. [How to ensure of quality on re-assembled product]We judge that the quality of re-assembled product is ensured if there is noproblem about the print result by adjustment program..1.3 DisassemblyThe flowchart below shows step-by-step disassembly procedures.

爱普生针式打印机维修手册全集OAZC。

COM 日期：2007-6-4 来源：IT168【IT168 使用技巧】本篇文章是“爱普生针式打印机维修”的下篇,主要是常见爱普生针式打印机的维修实例，对维修具有很大的参考价值，读者朋友可以借鉴学习。

爱普生针式打印机的维修（下）爱普生针式打印机故障实例LQ-300K打印体育*＊**时，使用LQ—300K 打印跳行，但使用1600K 打印正常。

故障分析：1、按照常规方法,进入LQ—300K 打印机的内部设置，查看其自动跳行是否打开,查看结果没有；2、怀疑进纸感应器不太好，更换感应器后，当时打印正常，不跳行，判定为感应器坏，打印一段时间（无规律)仍能出现跳行现象。

3、怀疑主板不好，首先更换主板的EEPROM，更换后也不正常，但一天不到故障依旧,然后更换主板，故障也依旧；4、怀疑电源板供电问题，更换后也一样跳行且时间不规律；5、最后判定PC 主板有问题，更换PC 后，测试无问题，一直至今正常.维修总结：PC 主板能兼容1600K 打印机，未必兼容LQ-300K 打印机.LQ-300K+：关于LQ-300K+打印机常见故障故障现象:打印机在高温20℃以上工作正常，低温8℃左右工作时开机无反应或反应慢（几秒或数分钟后）正常。

诊断与故障排除:就打印机在较高温度下能正常工作，低温下工作不稳定来判断可能是由于低温下电源负载能力低或集成电路功耗＊***，CPU 检测某部分电路工作状态不稳定而不能正常工作。

常温下测量电源输出——电压、电流、纹波时,纹波偏大。

此时打印机基本正常工作。

而低温下测量电源输出——电压、电源、纹波时，电源5V、3.3V 纹波大（600mv/300mv），线性差。

初步诊断为低温下主控电路功耗大,电源负载能力低，CPU 检测到电源特性差而中断工作。

将5V 电源滤波电容C54(470u/6。

3V）、3.3V 滤波电容C75（47u/35V）更换为C54（1000u/6.3V）、C75（220u/25V）后电源纹波正常（200mv/8mv）。
