Safety Precautions

All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this product.

DANGER

Strictly 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 or performing 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.

WARNING

Strictly 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. If any 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 use of such products containing flammable gas is prohibited.

PRECAUTIONS

Strictly 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 for electrician.

3.The power rating of this product is indicated on the serial number/rating plate. Never connect this product to the 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 charge right after the power turns off or after driving motors 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 handing FFC or cables.

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 board, connect them straight to the connectors to avoid slant insertion.

Confidential

7.In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components.

8.Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several times. 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 with soap 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 parts with sharp edges.

11.Use 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

ASF Scale

Coated surface of the PF Roller

Gears

Rollers

LCD

Scanner Sensor

Exterior parts

14.Never use oil or grease other than those specified in this manual. Use of different types of oil or grease may damage 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 the ink 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 which secure 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 to the corresponding attachment positions on the new one referring to the labels on the returned product.

Confidential

			Note *: For error codes, see Table 1-2 "Fatal Error List" (p.15).
	Power failure log*2		The information stored in this log is the same as the communication log.However, since the		Nonvolatile memory
	(Fax Log)		airtime is “Unknown” in this case, the result of it is recorded as “power failure”.

Note *1: The latest communication log for all destinations are printed in a list from when the sequential broadcast is executed. Cancellation is treated as a normal termination, therefore, if it is cancelled, the latest log is printed when the auto print setting is “always print”, and not printed when the setting is “only when an error occurs”. If “only when an error occurs” is selected, the log is printed even when an error occurs for just one destination.

*2: The power failure log when the sequential broadcast is being executed is not printed for the destinations to which the transmission log is already complete then. If the power failure occurs before the scheduled sending time when a broadcast is scheduled, the scheduled sending time is recorded.

The communication log is not stored under the following conditions:

When the sending operation is canceled which storing B&W image or waiting for redialing.

In the case of a power failure during the operation of sending/polling reception including waiting status for redial, or during receive operation.

When the receiving operation is canceled before the fax signal is detected.

If the fax signal is not detected during receiving operation.

If cancelled during the sequential broadcast.

(The log for the destinations of “not dialed yet” or “waiting for redial” is not saved except for those of which the communication is complete.)

1.1.4.2 Error Code/Superficial Phenomenon-Based Troubleshooting

This section explains the troubleshooting procedures based on the error codes and superficial phenomenon.

When an error occurs, it may be displayed on the LCD panel with a message instead of an error code. To check the error code, print out a fax log.

If the problem is not solved even after carrying out the remedy shown in the Table 1-8, print out a protocol trace to analyze the cause of the error.
