Solutions

Diagnóstico rápido

If the printer displays 0x50, the scanner carriage is likely jammed or failing to detect its starting position. You may hear a knocking sound as the motor attempts to push the scanner head against a barrier.

Solución paso a paso

  1. Power off the printer and unplug it from the wall outlet completely.
  2. Check for transport locks: Ensure any shipping tabs or switches under the scanner lid are moved to the unlocked position.
  3. Inspect the glass: Ensure nothing is trapping the scanner head underneath the glass panel.
  4. Perform a power cycle: Reconnect and restart; the scanner will attempt an automatic calibration.

Prevención y mantenimiento

Avoid placing heavy books or items on the scanner lid, as this can press down on the scanner glass and cause friction on the internal sensor head. Keep the scanner glass clean to prevent light calibration errors.

Cuándo llamar a un técnico

If the error 0x50 persists after a power cycle, the internal flex ribbon cable connecting the scanner head to the motherboard may be damaged, which requires professional disassembly.
