Solutions

Diagnóstico rápido

If you see the C-3103 error upon starting your bizhub 4020i, the scanner carriage is likely jammed or the motor lacks sufficient power to move. Listen for forced motor noises when attempting to start.

Solución paso a paso

  1. Complete power off: Turn off the printer and unplug it for at least 5 minutes.
  2. Physical release: Check that the scanner carriage is not obstructed in its natural movement (paper scraps, clips).
  3. Light cleaning: Remove any dust accumulated in the slide area.
  4. System reset: Power on to allow the scanner to recalibrate its initial position.

Prevención y mantenimiento

Avoid moving the multifunction printer without locking the scanner carriage if instructed by the manufacturer. Clean the scanner glass with a soft cloth. Keeping the environment dust-free reduces the risk of motor jams.

Cuándo llamar a un técnico

If the error persists after several resets, the scanner motor likely needs replacement or the flat data cable is damaged.
