Konica Minolta bizhub PRESS C2060L Error C-2451 Fix

The Konica Minolta bizhub PRESS C2060L error C-2451 refers to a motor rotation fault in the developing unit. This error occurs when the system detects increased mechanical resistance or a communication failure between the motor and the control board. Proper diagnosis involves clearing physical obstructions and checking the unit's electrical integrity. As a high-capacity production device, routine maintenance is essential to keep the engine running smoothly.

Common causes

  • 1Toner clumping causing mechanical drag on the developing gear assembly.
  • 2Wear on internal bearings leading to increased friction on the drive motor.
  • 3Contamination of the rotation sensor preventing proper speed feedback.
  • 4Loose or oxidized power cables feeding the developing unit drive motor.

Solutions

Diagnóstico rápido

The C-2451 error occurs when the motor governing the development process fails to achieve the target speed. If the machine emits grinding noises during initialization, suspect a physical blockage in the development gear train.

Solución paso a paso

  1. Power Cycle: Power off the machine completely and unplug it for 5 minutes to clear the sensor error state.
  2. Inspect Developing Unit: Remove the relevant developing unit and check for any physical blockages or toner buildup in the gears.
  3. Check Connectors: Examine the electrical contacts on the unit for any dust, debris, or bent pins.
  4. Re-initialize: Reinstall the units securely, power on the machine, and allow the system to perform a self-check.

Prevención y mantenimiento

Clean internal printer paths monthly to prevent dust buildup. Maintain stable environmental humidity, as it impacts developer health. Consistent use of genuine supplies significantly reduces the risk of motor failures.

Cuándo llamar a un técnico

If the motor continues to show mechanical resistance or grinding sounds after manual inspection, contact an authorized service technician to investigate the driving motor or controller board.
