Epson PX-M840F Error 0x21
If you encounter the Epson PX-M840F error code 0x21 displaying on your scanner, it indicates an issue related to the Scanner/ADF ALD PID excess speed error. This error can be caused by several factors, including ALD motor failure, motor driver failure, cable disconnection, or FFC disconnection.
When the ALD motor fails, it means there is a problem with the motor that drives the Automatic Document Feeder (ADF). This may result in the ADF not functioning correctly or not moving as it should. To troubleshoot this issue, you can start by checking if there are any visible signs of damage to the ALD motor. If you find any physical damage, it may be necessary to replace the motor.
Another possible cause of this error is a motor driver failure. The motor driver is responsible for controlling the ALD motor’s actions, and if it fails, it can lead to error code 0x21. In this case, you can try resetting the printer by turning it off for a few minutes and then turning it back on. If the error persists, it may require professional assistance to replace the motor driver.
Furthermore, a cable or FFC disconnection can also trigger this error code. Ensure that all the cables connecting the scanner and ADF are securely connected. If there are any loose connections or damaged cables, reconnecting or replacing them may resolve the issue.
To conclude, if you encounter the Epson PX-M840F error code 0x21, it implies possible issues with the ALD motor, motor driver, or cable/FFC connections. Performing basic troubleshooting steps such as checking for physical damage, resetting the printer, and verifying cable connections can help resolve this error. However, if the problem persists, it is recommended to seek professional help.
