Solutions

Diagnostic

The error appears when switching on the unit. If the carriage hits the end of the path repeatedly, there is a problem with the position detection (home sensor).

Troubleshooting steps

  1. Ensure the scan glass has no adhesive residue.
  2. Carefully clean the steel rail with a dry cloth.
  3. Verify that the flat cable connecting the carriage to the main board is not cut.
  4. Restart the printer.

Prevention and maintenance

Cleaning of moving parts should be done every 6 months. Do not force the scanner manually while the printer is switched on.

When to call a technician

If the carriage moves but still reports C3100, the scanner motor control board needs to be replaced professionally.
