Epson WF-C5790 Error 0x0090
The Epson WF-C5790 printer sometimes encounters an error code 0x0090, which is displayed as “STK PID lock error.” This error indicates that the Stacker motor did not run properly, likely due to an overload in the mechanism.

To troubleshoot this issue, there are several steps you can take. Firstly, check for any visible damage on the gears, FFC, or motor. Replace any broken or damaged parts as necessary. Clean the Stacker motor encoder scale and ensure that it is free from any debris or contamination. Reset the printer by turning it off and unplugging it for a few minutes, then plug it back in and turn it on.
If the issue persists, it may be necessary to replace the Stacker motor or the main board of the printer. In such cases, it is recommended to contact Epson’s customer support or a professional technician for further assistance.
In summary, the Epson WF-C5790 printer may display error code 0x0090 indicating a Stacker motor malfunction.
