Fix C6000 Error on Kyocera TASKalfa 2552ci: Fusing Issue

The C6000 error code in the Kyocera TASKalfa 2552ci signals a critical failure in the fusing unit. This issue occurs when the thermal sensor detects that the temperature is not rising or staying outside of normal operating parameters. Addressing it immediately is crucial to avoid damage to the heat roller or internal sensors.

Common causes

  • 1Halogen lamp failure in the fuser due to end of service life.
  • 2Dirty thermistor failing to detect the actual temperature.
  • 3Loose or damaged electrical connection after a severe paper jam.

Solutions

Fuser Unit Connection Check

  1. Turn off the equipment using the main power switch.
  2. Carefully remove the fuser unit using the blue levers.
  3. Verify that electrical connectors are clean and show no signs of burning.
  4. Reinstall the unit and ensure it clicks into the rails.

Temperature Sensor Verification

  1. Access service mode (U000).
  2. Run simulation U061 to check the current fuser temperature.
  3. If the reading is incorrect, the thermistor requires cleaning or technical replacement.

Steps to follow

  1. 1

    Power down

    Switch off the device and wait 20 minutes to allow the fuser area to cool down.

  2. 2

    Visual inspection

    Remove the fuser and check for paper scraps or melted toner.

  3. 3

    System reset

    After securing the area, restart the copier to check if the error persists.

Frequently asked questions

It is not recommended, as this code indicates a thermal problem that could lead to internal damage if forced.

Mainly access to service codes (U-codes) and basic cleaning supplies; component replacement requires original spare parts.

It is a standard wear-and-tear code in high-volume devices, typically associated with the fuser maintenance kit life cycle.
