Konica Minolta bizhub PRESS C2060L Error C-2551 Fix

The Konica Minolta bizhub PRESS C2060L error C-2551 is a service notification indicating a malfunction in the charging unit. It triggers when the cleaning motor is stuck or a high-voltage irregularity occurs. Immediate inspection of the unit is required to prevent secondary damage to the drums. This component is central to the image formation process and requires regular attention.

Common causes

  • 1Broken corotron wire preventing uniform electrostatic charging.
  • 2Toner accumulation causing current leakage to ground.
  • 3Cleaning motor jammed by compacted waste toner.
  • 4High-voltage terminal failure due to heavy oxidation.

Solutions

Diagnóstico rápido

The C-2551 error blocks startup. If you notice a faint smell of ozone or clicking when trying to boot, the corotron is likely experiencing an electrical short.

Solución paso a paso

  1. Unit Inspection: Remove the charging unit (corotron) and verify the charging wire is intact and contacts are clean.
  2. Contact Cleaning: Clean the electrical terminals with isopropyl alcohol to ensure stable high-voltage transmission.
  3. Reinstall Unit: Reinsert the unit firmly, ensuring it clicks into place before powering on.
  4. Clear Debris: Remove any visible toner buildup inside the unit casing that may be facilitating a short circuit.

Prevención y mantenimiento

Periodically operate the manual corotron cleaning slider. Avoid low-grade third-party toner, as higher debris levels accelerate the fouling of high-voltage components.

Cuándo llamar a un técnico

If the error persists after cleaning, the high-voltage power board or the cleaning motor internal to the charging unit has likely reached end-of-life and needs professional intervention.

Frequently asked questions

This error points to a charger unit fault, typically triggered by a short circuit, broken wire, or stuck cleaning motor.

No, the error prevents operation to protect the photosensitive drum from potential high-voltage arching.

The charging (corotron) unit is the main replaceable part. Original units are critical for machine safety.

Use the manual cleaning slider integrated into the corotron unit regularly to maintain wire cleanliness.
