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, fo r 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. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static
wrist straps, when accessing internal components.
6. 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.
7. 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.

8. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts
with sharp edges.
9. Use only recommended tools for disassembling, assembling or adjusting the printer.
10. Observe the specified torque when tightening screws.
11. Be extremely careful not to scratch or contaminate the following parts.
Nozzle plate of the Print Head
CR Scale
PF Scale
ASF Scale
Coated surface of the PF Roller
Gears
Rollers
LCD
Scanner Sensor
Exterior parts
12. 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.
13. Apply the specified amount of grease described in this manua l .
14. Make the specified adjustments when you disassemble the printer.
15. When cleaning this product, follow the procedure described in this manual.
16. When transporting this product after filling the ink in the Print Head, pack the printer without removing the
ink cartridges in order to prevent the Print Head from drying out. In addition, make sure to secure the CR
Unit with tape before packing the printer "5.2 Protection for Transportation" (p284).
17. Make sure to install antivirus software in the computers used for the service support activities.
18. Keep the virus pattern file of antivirus software up-to-date.

1.1 Troubleshooting
This section describes the troubleshooting workflow.
1.1.1 Troubleshooting Workflow
The following page describes the troubleshooting workflow. Follow the flow when troubleshooting problems.
This flowchart is compiled based on the following contents.
• Our experience regarding the quality problem
• Printer Mechanism specification for WF-8510/WF-8590 Series/WF-8010/WF-8090
Series
WF-8010/WF-8090 Series does not have the Scanner/ADF unit, so the troubleshooting for
the Scanner/ADF unit is not applicable to this series.
When FAX related error occurs, see " 1.3.1 FAX Troubleshooting (WF-8510/WF-8590
Series only) (p30)".

1.2 Power-On Sequence
This section describes the power-on sequences for this product. The preconditions are as follows.
The following explains how to use the simplified diagrams in Table 1-1 or Table 1-2. The
diagrams show the movement of each component as seen from the front of the printer.
Figure 1-4. Movement of Components
Normal power-on sequence
No error occurred at the last power-on, and the power was turned off normally.
Initial ink charge has finished and every cartridge has sufficient ink.
No paper on the paper path.
The Printhead is capped by the cap of the Ink System.
CR Lock is engaged normally.
This indicates the Simple Sequence.
PG position is set to PG 1.
Option Cassette Unit is not installed.

3. Seeking the home position
3-1.To identify the CR Unit position, the CR Motor rotates
counterclockwise and it confirms the CR Unit touches the Right Frame
slowly. It regards the point when the CR Unit touches the Right Frame
as the position specified steps away from the home position, and sets it
as the origin.
3-2.If it judges the CR Unit is in the home position, the PF Motor rotates
clockwise and resets the CR lock.

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 information stored in this log is the same as the communication log. However, since the
airtime is “Unknown” in this case, the result of it is recorded as “power failure”.
The communication log is not stored under the following conditions:
When the sending operation is canceled while 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 re-dial” is not saved except
for those of which the communication is complete.)

1.3.1.2 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 1-11,
print out a protocol trace to analyze the cause of the error.
