Common causes

  • 1Physical obstruction of the scanner carriage due to debris.
  • 2Wear and tear on the transmission belt that moves the scanner lamp.
  • 3Home sensor failure preventing the unit from finding the start position.
  • 4Loose or failing ribbon cable (FFC) connecting the scanner head.

Solutions

Diagnóstico rápido

Error 805 appears immediately upon initiating a scan. If you notice the scanner lamp flickering without moving, the fault is likely in the drive mechanism or the calibration strip detection.

Solución paso a paso

  1. Manual calibration: Clean the glass exposure and the white calibration strip to allow the sensor to detect the document start position.
  2. Unit reset: Power off the unit and wait for the scanner carriage to return to its home position.
  3. Check connections: Ensure the scanner ribbon cable hasn't loosened after moving the machine.
  4. Scan test: Try making a copy to verify if the scanner carriage completes its sweep.

Prevención y mantenimiento

Clean the exposure glass with a dry, soft cloth regularly. Avoid abrasive cleaners. Keep the workspace dust-free to prevent debris ingress into the scanner mechanism.

Cuándo llamar a un técnico

If you hear clicking or if the carriage remains stationary despite cleaning, the scanner belt or carriage motor needs replacement by a professional technician.

Frequently asked questions

This error indicates that the scanner carriage failed to complete the initial calibration or detection movement when scanning or copying.

Yes, keep the exposure glass free of dust and avoid sudden physical impacts to the printer, as they can misalign the scanner components.

Not directly, but using original toner helps prevent internal toner dust accumulation, which could eventually clog the scanner unit.

If you hear grinding noises or the carriage stops midway, there is likely mechanical damage to the scanner carriage motor.
