Solutions

Diagnóstico rápido

The C360 error appears as a motor failure alert on the control panel. If you hear grinding or clicking noises, it indicates a physical obstruction or mechanical failure within the developer unit assembly.

Solución paso a paso

  1. Visual inspection: Open the front door and carefully extract the developer unit. Check for paper scraps or impacted toner blocking the gears.
  2. Clean contacts: Use compressed air to clean the electrical connectors on the back of the unit.
  3. Re-seat: Re-insert the unit, ensuring it clicks firmly into place on its rails.
  4. Motor test: Turn the device on; if you hear continuous clicking, the drive motor gear is likely stripped and needs professional replacement.

Prevención y mantenimiento

  • Replace the developer unit according to the recommended service cycle (150k-300k prints).
  • Avoid shaking toner cartridges excessively, as this causes toner clumping that blocks the developer unit.
  • Use only original T-3008E series toner to prevent developer powder contamination.

Cuándo llamar a un técnico

The C360 requires handling the core developing system. If the motor does not respond after cleaning, the motor assembly or gears must be replaced by an authorized technician.
