Konica Minolta bizhub C222 Error C-2558: Motor Failure

The Konica Minolta bizhub C222 error c-2558 is a mechanical alert indicating a problem in the toner transport system. This error occurs when the motor responsible for supplying powder from the cartridge to the developer unit does not rotate at the configured speed, possibly due to a physical obstruction or an electronic failure in the rotation sensor. Correct resolution is vital to avoid overloading or exhausting the developer unit.

Common causes

  • 1Compacted toner inside the cartridge creating excessive resistance for the motor.
  • 2Toner Supply Motor failure due to natural gear wear.
  • 3Accumulated dirt on the toner density sensor in the developer unit.
  • 4Poorly inserted motor connector on the logic board (after maintenance).

Solutions

Quick Diagnosis

The error usually appears after changing a toner cartridge or after prolonged use. If when removing the toner you hear a grinding noise or see the cartridge jammed, the problem is mechanical. If the cartridge looks perfect, the fault is electrical in the rotation motor or the power board.

Step-by-Step Solution

  1. Rotation Test: Remove the toner cartridge and manually rotate the auger gear. If it feels stiff, the toner is compacted.
  2. Sensor Cleaning: Clean the surface of the toner sensor in the developer unit with a dry cloth to remove dust that prevents clear reading.
  3. Diagnostic Test: In service mode, run the motor test. If the motor does not attempt to spin, the wire connections or the motor itself are faulty.
  4. Replacement: If the motor emits constant humming sounds but doesn't spin, replace the corresponding supply motor.

Prevention and Maintenance

Always use original cartridges to ensure powder fluidity. Perform a general cleaning of the toner motor gears every 150,000 prints to prevent locks due to toner residue that solidifies with ambient humidity.

When to Call a Technician

If after cleaning the sensor and verifying that the motor receives power, the error persists, it is necessary to change the toner supply motor assembly. This task requires partial disassembly of the equipment.

Equipment Technical Data

  • Technology: Color Laser MFP
  • Speed: 22 ppm
  • Connectivity: Ethernet 10/100/1000 Mbps
  • Capacity: Up to 3,650 sheets
  • Consumables: TN-216 family (CMYK)
  • Recommended Use: Offices with mid-volume printing
  • Official Drivers / Firmware

Steps to follow

  1. 1

    Cartridge check

    Remove the indicated toner cartridge and check that the internal auger rotates freely.

  2. 2

    Sensor cleaning

    Clean the toner sensor window that detects powder presence inside the developer unit.

  3. 3

    Motor reset

    Enter Service Mode (Tech Rep Mode) and perform a 'Toner Motor Test' to verify its functionality.

Frequently asked questions

Error C-2558 indicates that the toner supply motor does not reach the rotational speed required by the system.

Yes, if toner is not supplied correctly, the mixture in the developer unit degrades quickly.

Always use original TN-216 toner; generics often lack fluidity and jam the motor.

You can try basic cleaning, but if the motor is burned out, professional replacement is required.
