Fatal Error Code on Epson WF-2520, WF-2521, WF-2528

The fatal error code is stored in the EEPROM on the Main Board and can be read out using the Adjustment Program. The code can be displayed on the LCD of the control panel by a special panel operation. The way to display the Fatal Error Code is to press 3 buttons simultaneously when a fatal error occurs. Three buttons that must be pressed simultaneously are Menu + Stop + OK. Please look at the image below.

Error type: Circuit error

Error code	Error name	Possible cause
80H	Circuit error (include blowout of a fuse)	• Main Board failure

Error type: PIS Board device error

Error code	Error name	Possible cause
83H	Reflector no reflection error	• Defective Fault Detection Plate* (detachment, peeled reflector) • Sensor failure (contaminated Sensor, damaged FFC, PIS Board installation failure)
88H	Excessive Light error	• Abnormal sensor output (Sensor failure, PIS Board failure) • Unexpected excessive amount of light such as too much diffused light from outside is shed on the sensor because the housings are removed (When used outdoors or near the window where direct sunlight comes in)
89H	Insufficient Light error	• Sensor failure (PIS Board installation failure, contaminated Sensor) • Abnormal sensor output (Break of FFC during printer operation, PIS Board failure) • Unable to accurately detect where the fault detection plate is because too much diffused light from outside is shed on the sensor. (When used outdoors or near the window where direct sunlight comes in) • Ink Cartridge failure (contaminated/damaged prism)

Questions and Answers

Q: Error Code: 20000xxx when using the Adjustment Program. What to do?
A: Communication error! Error Code: 20000xxx occurs because the printer is not ready to accept commands from the Adjustment Program because it is still busy processing the previous command.

So when the printer receives the command example Main pad counter - Check, the power light will blink for about 60 seconds. The printer can process the next command example Main pad counter - Initialization after 60 seconds have passed. Communication error! Error Code: 20000xxx occurs because the second command "Main pad counter -> Initialization" is done while the printer is still processing the previous command. So wait for the power light to stop flashing, then run the next command.

When there is damage to the Epson printer and requires replacement of spare parts, after the damaged parts are replaced, then use the Adjustment Program to reset the printer so that it can work optimally with new spare parts. If you are having trouble repairing a faulty printer yourself, we recommend contacting an Epson Authorized Customer Service Center.
