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.

EPSON喷墨打印机维修方法及技巧
EPSON喷墨打印机维修方法及技巧随着电脑市场的降价，电脑已成为更多人可以接受的工具，很多家庭级的打印机也展现电脑爱好者面前。
如EPSON 的480、580、670、PHOTOEXT系列等。
这里根据个人几年来对EPSON打印机的使用经验，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。
A、更换墨盒第一种：墨尽灯闪烁时，按下“清洗”键3秒，打印头归位到更换墨盒位置，换上新墨盒，再次按下“清洗”键，打印机随后进行新墨盒检测及清洁工作。
第二种：墨尽灯没有闪烁，但打印质量下降（彩色墨盒中有一色墨尽），清洁工作也无法完成时。
想更换墨盒时，很多人可能是强行断电，这样对打印机难免会造成损坏，这里给大家介绍另一种方法：开机后，按下“进纸”键5秒，打印头归位到更换墨盒位置，随后步骤与上一样。
B、开机后所有灯闪烁打印机由于机械故障（打印头阻力过大）造成打印头的运动受阻，引起打印头撞击机械框架，使打印头定位系统出错，和卡纸，使打印机无法正常复位，然后所有指示灯闪烁。
第一种：同时按下“进纸”、“清洗”键开机，这时“进纸”灯闪烁，然后松手按下“清洗”键，直到所有灯闪烁一下后熄灭，这时打印机正常。
此种方法有99%的修复率，此种方法虽很简单，但EPSON公司从未公开。
第二种：以上方法不行的话，问题可能出在主板上，首先取下面盖，取出主板（从后面及旁边取出镙钉），先不要拔下主板上的联线，取下主板上的锂电池（3V）后开机，问题解决。
因为此电池是为打印机保存BIOS、打印机信息的。
第三种：此种情况是一般不会产生的。
但在我维修众多EPSON打印机中还是遇到了几例情况。
主板上有一个串行EPROM（93C46）芯片中的程序乱了，因为此芯片是为打印机记忆打印头信息的，更换此芯片有相当大的难度：首先要找一台同型号的打印机，取下此芯片（93C46），买一颗芯片（93C46，大约5.00元），用写入器将取下的芯片里的程序复制到新买的芯片中，问题解决。
