Common causes

  • 1Obstruction: Debris in the rail path preventing smooth movement.
  • 2Disconnection: Data ribbon cable loosened due to machine vibrations.
  • 3Sensor failure: Home position sensor failing to detect the carriage.
  • 4Electrical fault: Scanner motor lacking power due to main driver damage.

Solutions

Diagnóstico rápido

If the device shows C-D160 when scanning, the scanner is trying to calibrate but fails to receive a signal from its Home Position sensor. Check if the scanner carriage attempts to move upon startup; if it stays completely still, the issue is likely electrical.

Solución paso a paso

  1. Power off and unplug the device to avoid electrical hazard.
  2. Lift the document cover and check if the glass is clean and the carriage moves freely without debris.
  3. Verify the transport lock (if the machine was recently relocated, ensure the lock is set to 'open').
  4. Power on and observe if the carriage manages to return to its home position during the self-test.

Prevención y mantenimiento

  • Keep the exposure glass free of dust using an anti-static microfiber cloth to prevent read errors.
  • Avoid jarring or moving the device while the scanner is in resting mode.
  • Update the firmware via the official website if the control panel shows erratic behavior.

Cuándo llamar a un técnico

If the scanner carriage does not move at all upon power-up, the motor or the flat data cable might be damaged. This requires internal technical opening of the unit.
