Epson WF-3720-3723-3725 Error 0x003E
Epson WF-3720-3723-3725 printers may encounter an error code 0x003E displayed as “ASF (1st) PID excess speed error. Encoder error. Contaminated encoder scale. Disconnected or broken FFC. Encoder sensor failure. Motor driver failure. Main board failure.” This error is related to various issues within the printer’s components. Here are some common problems associated with this error and possible troubleshooting steps:
1. Contaminated Encoder Scale: Check if there is any dirt, ink, or debris on the encoder scale, which is a thin strip located near the printhead. Clean it gently using a lint-free cloth or a small brush.
2. Disconnected or Broken FFC (Flat Flexible Cable): Inspect the FFC that connects the encoder sensor to the printer’s main board. Ensure it is properly connected and not damaged. If necessary, reconnect or replace the FFC.
3. Encoder Sensor Failure: The encoder sensor measures the position of moving parts inside the printer. Verify if it is functioning correctly. If not, it may need replacement. Consult the printer’s manual or contact Epson support for assistance.
4. Motor Driver Failure: The motor driver controls the movement of the printer’s components. If it fails, the printer may face difficulties in moving or aligning. Consider seeking professional help or contacting Epson support to diagnose and fix this issue.
5. Main Board Failure: In rare cases, the error code 0x003E may indicate a failure in the printer’s main board. It is recommended to consult a professional technician or Epson support for further assistance and potential replacement of the board.
Remember, if you are unsure about any troubleshooting steps or unable to resolve the error, it is best to reach out to the product manufacturer or authorized service provider for accurate diagnosis and resolution of the issue.
