Common causes

  • 1ATDC sensor degraded by usage.
  • 2Developer contamination with external dirt.
  • 3Disconnected sensor signal cable.
  • 4Logical failure in density control.

Solutions

Quick Diagnosis

The error C-2558 occurs when the ATDC sensor cannot automatically calibrate density after use or consumible changes.

Step-by-step solution

  1. Inspection: Verify ATDC sensor electrical connections.
  2. Cleaning: Remove any dirt around the developer.
  3. Calibration: Execute the developer initialization command (F8) from technical mode.
  4. Replacement: Replace the sensor if the error persists.

Prevention and maintenance

The ATDC sensor is vital. Keep the equipment dust-free and ensure toner is genuine to avoid density variations.

When to call a technician

The ATDC sensor recalibration requires CE mode access. Do not attempt to change the sensor yourself without documentation.
