Solutions

Quick Diagnostics

The C-2558 error is typically linked to a lack of toner in one of the developer units or a faulty density sensor. First, verify the toner levels on the control panel.

Step-by-step Solution

  1. Check toner: Verify if the color cartridge has enough toner installed.
  2. Readjust: Open and close the front door to force a new toner detection cycle.
  3. Restart: Power off and on to let the machine attempt to calibrate the developer automatically.
  4. Test: Perform a test print after calibration to ensure stable color output.

Maintenance and Prevention

Always use genuine TN-P73 series consumables. Generic toners often contain particles that alter developer unit calibration.

When to call a technician

If the C-2558 error persists after replacing toner, there is an internal fault in the toner concentration sensor or an electrical issue in the developer unit.
