Epson ET-3700 Error 0x0090
The Epson ET-3700 printer may encounter an error code 0x0090, which is displayed as “STK PID lock error.” This error indicates that the Stacker motor did not run due to various reasons, such as an overload of the mechanism, broken gears, encoder failure, contamination of the Stacker motor encoder scale, damaged FFC, failure of the Stacker motor encoder sensor, failure of the Stacker motor, or failure of the main board.
To troubleshoot the issue, you can try the following steps. Firstly, check for any visible damage to the printer, such as broken gears or loose connections. Ensure that there is no obstruction in the Stacker motor’s movement, which could cause an overload. If the error persists, clean the Stacker motor encoder scale to remove any contamination that may interfere with its functioning.
Inspect the FFC (Flexible Flat Cable) for any signs of damage. If you find any issues, it may need to be replaced. Additionally, check the Stacker motor encoder sensor for any damage or misalignment. If necessary, realign or replace the sensor.
If none of the above steps resolve the error, there may be a failure in the Stacker motor or the main board. In such cases, it is recommended to seek professional assistance for further diagnosis and potential repairs.
It is important to note that these troubleshooting steps are general suggestions and may not be applicable to all situations. It is always advisable to consult the printer’s user manual or contact Epson support for specific guidance based on your printer model and error code.
