Konica Minolta bizhub 287 error C-2557 Explained
Konica Minolta bizhub 287 error C-2557 occurs when the ATDC sensor fails to detect the proper toner concentration in the development unit. This bizhub 287 toner sensor problem can block printing tasks. Resolving this issue usually involves checking the toner installation or cleaning the internal sensor surfaces.
Common causes
- 1Excess toner residue obscuring the ATDC sensor lens.
- 2Empty toner cartridge failing to signal replenishment.
- 3Faulty connection between the sensor and the main board.
- 4Use of low-quality or non-compatible toner powder.
Solutions
Diagnóstico rápido
The C-2557 error is reported by the system as a toner density control failure. If your bizhub 287 displays this message, the machine has lost contact with the toner supply level, effectively stopping the development process.Solución paso a paso
- Toner check: Remove the toner cartridge and ensure there are no obstructions in the intake path.
- Sensor cleaning: Carefully clean the ATDC sensor area with a dry cloth, removing any spilled toner powder.
- Manual load: Enter service mode and run the manual toner supply command to verify if the sensor detects the change.
- Test print: Confirm proper operation by running a print job.
