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.
Confidential
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 ScalePF ScaleASF ScaleCoated surface of the PF RollerGearsRollersLCDScanner SensorExterior 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.

1.3.1.1 FAX Log
When an error related to fax occurs, it is not only indicated on the LCD but also saved as a log file. The error code is recorded in it, and according to this log, the contents of the error can be confirmed.
Table 1-7. FAX Log (1)
Log Name Description Save Destination
Latest log (Last Transaction)

The following information is stored.
Communication log (Fax Log)
Note *: For error codes, see Table 1-9. Error Code List (p.31).
Power failure log (Fax Log)
Note *1:The latest communication log for all destinations are printed in a list form when the sequential broadcast is executed.

Cancellation is treated as a normal termination, ther efore, if it is cancelled, the latest log is printed when the aut o print s etting 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.
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.)
