Solutions

Diagnóstico rápido

If you hear a loud buzzing or mechanical noise from under the scanner cover upon startup, the drag mechanism is obstructed or the motor has failed.

Solución paso a paso

  1. Power cycle: Power off and unplug the unit for 10 minutes to discharge static power.
  2. Inspection: Visually check under the scanner glass to ensure the sensor block isn't trapped.
  3. Firmware: If the scanner mechanism seems functional but gives the error, update the device firmware.
  4. Test: Power on the printer and listen to see if the error repeats after the system self-check.

Prevención y mantenimiento

Do not place heavy objects on the scanner lid, as this puts pressure on the glass and limits the internal movement of the sensor. Run semi-annual firmware updates to optimize all motor movements.

Cuándo llamar a un técnico

If the 'Print Unable 04' error persists and you hear grinding noises from the scanner assembly, the motor is physically broken and requires replacement by a professional technician.
