Epson WF-5790 Error 0x02C8
The Epson WF-5790 printer may display the error code 0x02C8, accompanied by the message “EJ2 load position excess speed error. Failed to read The EJ2 motor encoder.” This error could occur due to several reasons, such as contamination of the EJ2 encoder scale, skew or damage of the EJ2 encoder FFC (Flexible Flat Cable), failure of the EJ2 encoder sensor, failure of the EJ2 motor driver, or failure of the main board.
One possible cause for this error is contamination of the EJ2 encoder scale. Dust or debris on the scale can interfere with proper reading of the motor encoder, leading to the error. Cleaning the encoder scale with a soft, lint-free cloth might resolve the issue.
Another potential cause could be the skew or damage of the EJ2 encoder FFC. This could occur due to improper handling or wear and tear over time. In such cases, examining the FFC for any visible damage and replacing it if necessary can help rectify the problem.
The failure of the EJ2 encoder sensor or motor driver could also result in the error code 0x02C8. In such situations, contacting Epson customer support or a professional printer technician for assistance is recommended.
Lastly, a rare possibility is the failure of the main board. This component might require professional inspection and replacement if deemed necessary.
When encountering the Epson WF-5790 error code 0x02C8, troubleshooting steps involving cleaning, inspecting, and potentially replacing certain components could be attempted. However, for complex issues like main board failure, seeking technical expertise is advised.
