Solutions

Diagnóstico rápido

The SC122 appears during printer boot-up. If you hear an unusual, high-pitched whirring sound before the error shows up, the motor bearings may be failing.

Solución paso a paso

  1. Reset: Power off the unit completely for 5 minutes to clear temporary sync errors.
  2. Check power: Confirm stable electrical grounding for the device.
  3. Monitor: Power on and verify if the 'Ready' status is achieved or if the error persists.

Prevención y mantenimiento

Dust is the enemy of high-performance optics. Maintain clean office environments to ensure the scanner motor remains dust-free.

Cuándo llamar a un técnico

The SC122 is a hardware-based motor failure. If a reboot doesn't clear it, contact service for an optical unit replacement.
