(1) 打印机设置1) 基本设置基本设置根据用户需要修改或取消工厂设置的某些打印机功能。

a.警告提示页输出禁止禁止输出警告提示页时，设置此程序。

b.打印测试页输出禁止用来禁止打印测试页。

设定此项设置后，就不能再通过用户设置(测试页打印) 打印测试页。

c.A4/信纸类型自动转换需要用信纸进行打印，但没有信纸时此设置允许将打印内容切换到A4纸上进行打印。

*A4纸张缺少时，不允许将打印内容输出到信纸尺寸的纸张上。

d.保持数据删除此程序用来手动删除硬盘上所有数据。

e.内存满时的输出方法打印机数据内存满时，无法再进行更多内容打印。

所以，此时机器打印保存在内存中的数据。

此程序用来设置打印条件，工厂默认设置为“1”。

AR-C260M打印部分13 –92) 接口设置接口设置用来设置数据监视，以及控制数据到机器并行口和网络端口的输出。

a.端口选择方法用来选择机器的并行口和网络端口。

设置项目项目内容工作结束后改变打印完成后，端口选择被设置成自动。

I/O 超时后改变当达到I/O超时设置所设的时间( 以下所列项目) 时，端口选择变成自动选择。

b. 并行口允许设置此程序用来设置从并行口打印的允许/禁止。

c. USB端口允许设置此程序用来设置从USB端口打印的允许/禁止。

d. 网络端口允许设置此程序用来设置从网络端口打印的允许/禁止。

e. I/O 超时时间端口在打印数据接收等待状态时，经过一段时间端口没有收到打印数据后，此程序用来中断端口的连接，同时用来自动选择端口，并启动端口待机状态等待接收下次打印数据进行打印。

I/O 超时项表示打印数据接收等待状态到I/O端口超时之间的时间间隔。

3) 网络设置此设置用来将打印机设置成网络打印机。

网络设置可以设置以下这些项目。

改变设置项目后，终止管理者程序，关闭机器主开关，稍等片刻后重新打开机器主开关，设置被确认。

a.IP地址设置机器在TCP/IP网络协议环境下运行时，可以用此设置来设定机器的IP地址。

复印机整理维修手册全集第一、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。

EPSON disclaims any and all rights in those marks.Copyright 2017SEIKO EPSON CORPORATIONP・CS Quality Assurance DepartmentSafety PrecautionsAll safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this product.DANGERStrictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life. 1.Always disconnect the product from the power source and peripheral devices when servicing the product orperforming maintenance.2.When performing works described in this manual, do not connect to a power source until instructed to do so.Connecting to a power source causes high voltage in the power supply unit and some electronic components even if the product power switch is off. If you need to perform the work with the power cable connected to a power source, use extreme caution to avoid electrical shock.WARNINGStrictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.1.Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. Ifany ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.2.When using compressed air products; such as air duster, for cleaning during repair and maintenance, the useof such products containing flammable gas is prohibited.PRECAUTIONSStrictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.1.Repairs on Epson product should be performed only by an Epson certified repair technician.2.No work should be performed on this product by persons unfamiliar with basic safety knowledge required forelectrician.3.The power rating of this product is indicated on the serial number/rating plate. Never connect this product tothe power source whose voltages is different from the rated voltage.4.Replace malfunctioning components only with those components provided or approved by Epson;introduction of second-source ICs or other non-approved components may damage the product and void any applicable Epson warranty.5.The capacitors on the Main Board may be electrically charged right after the power turns off or after drivingmotors which generates counter electromotive force such as when rotating the PF Roller or when moving the CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the capacitors on the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/ reassembly.6.To prevent the circuit boards from short-circuiting, be careful about the following when handling FFC orcables.⏹When handling FFC, take care not to let the terminal section of FFC touch metal parts.⏹When connecting cables/FFC to the connectors on circuit boards, connect them straight to the connectors to avoidslant insertion.7.In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-staticwrist straps, when accessing internal components.8.Do not tilt this product immediately after initial ink charge, especially after performing the ink charge severaltimes. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads to completely absorb ink wasted due to the ink charge.9.Never touch the ink or wasted ink with bare hands. If ink comes into contact with your skin, wash it off withsoap and water immediately. If you have a skin irritation, consult a doctor immediately.10.When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal partswith sharp edges.e only recommended tools for disassembling, assembling or adjusting the printer.12.Observe the specified torque when tightening screws.13.Be extremely careful not to scratch or contaminate the following parts.⏹Nozzle plate of the printhead⏹CR Scale⏹PF Scale⏹Coated surface of the PF Roller⏹Gears⏹Rollers⏹LCD⏹Scanner Sensor⏹Exterior parts14.Never use oil or grease other than those specified in this manual. Use of different types of oil or grease maydamage the component or give bad influence on the printer function.15.Apply the specified amount of grease described in this manual.16.Make the specified adjustments when you disassemble the printer.17.When cleaning this product, follow the procedure described in this manual.18.When transporting this product after filling the ink in the printhead, pack the printer without removing theink cartridges in order to prevent the printhead from drying out.19.Make sure to install antivirus software in the computers used for the service support activities.20.Keep the virus pattern file of antivirus software up-to-date.21.When disassembling/reassembling this product, if you find adhesive power of the double-sided tape whichsecure the parts or FFC is not enough, replace the tape with new one and attach it correctly to the specified points where the parts or FFC should be secured.22.Unless otherwise specified in this manual, the labels attached on the returned product should be transferred tothe corresponding attachment positions on the new one referring to the labels on the returned product.About This ManualThis manual, consists of the following chapters, is intended for repair service personnel and includes information necessary for properly performing maintenance and servicing the product.CHAPTER 1. TROUBLESHOOTINGDescribes the step-by-step procedures for the troubleshooting.CHAPTER 2. DISASSEMBLY / REASSEMBLYDescribes the disassembly/reassembly procedures for main parts/units of the product, and provides the standard operation time for servicing the product.CHAPTER 3.
