Solutions

Diagnóstico rápido

The C-2259 error is usually accompanied by physical resistance in the developer motor. Listen for unusual grinding sounds on startup. If these are present, the mechanical issue is confirmed.

Solución paso a paso

  1. Power down: Turn off the power switch.
  2. Manual check: Pull out the imaging unit and rotate the gears by hand.
  3. Re-engage: Power on; if it clicks and errors immediately, the motor needs replacement.

Prevención y mantenimiento

Follow all scheduled preventive maintenance intervals. Old toner can clump and act as a brake on the developer rollers, forcing the motor to work harder.

Cuándo llamar a un técnico

If mechanical resistance is identified or the error persists, do not force the machine. Contact a certified technician as this requires motor replacement.
