Solutions

Diagnóstico rápido

If the machine displays C-2557, the sensor in the developer unit detects an imbalance. Why is my Konica Minolta bizhub C225 showing C-2557 error? The mix of toner to developer is outside operational parameters.

Solución paso a paso

  1. Inspect Toner: Check if the toner cartridge is empty or low.
  2. Reseat Cartridge: Remove and gently shake the toner cartridge.
  3. Test: Check if the system initiates a toner load cycle.
  4. Check Developer: Consult technician to verify developer unit concentration levels.

Prevención y mantenimiento

Always replace TN-221 toner cartridges as soon as the low-toner indicator appears. Professional servicing is recommended every 50,000 prints to maintain sensor accuracy.
