  • 1Physical obstruction in the scanner path.
  • 2Misalignment of the reader carriage.
  • 3Wear of the scanner's internal drive belt.
  • 4Electronic sensor failure on the carriage rail.

Solutions

Diagnóstico rápido

If the printer makes grinding noises from the scanner bed or shows error 0x55, the scanner carriage has failed its startup sequence. Check if the path is physically blocked.

Solución paso a paso

  1. Check carriage: Ensure there is nothing obstructing the scanner's movement path.
  2. Power cycle: Unplug the printer to reset the scanner motor logic.
  3. Clean glass: Clean the scan glass to rule out false sensor errors.
  4. Test: Perform a copy to check if the error is resolved.

Prevención y mantenimiento

Avoid putting heavy items on the scanner cover to keep the delicate carriage rails aligned. Keep the machine in a clean environment to prevent dust from interfering with internal scan sensors.

Cuándo llamar a un técnico

If the error continues after a reset, the scanner motor or drive belt is likely failing, requiring technical repair or replacement of the scanner module.
