Common causes

  • 1Contamination of the alignment sensor by toner dust.
  • 2Surface damage to the transfer belt.
  • 3Registration sensor communication failure.
  • 4Misaligned toner cartridge blocking the path.

Solutions

Quick Diagnosis

The error 006 occurs when the printer attempts to calibrate colors automatically. If previous prints showed misalignment (double image), the 006 is the final result of this alignment failure.

Step-by-Step Solution

  1. Power off: Disconnect the printer from power to release logical locks on the registration sensors.
  2. Inspect transfer belt: Open the front cover and check if the transfer belt has any dust or toner residue obstructing the alignment sensors.
  3. Print test: Power the unit back on and trigger a 'Color Calibration' from the control panel to reset the registration process.

Prevention and Maintenance

Regularly clean the LED head lenses and registration sensors located near the transfer belt. Use only original OKI consumables to ensure color registration compatibility.

When to Call a Technician

If after cleaning and forced calibration the 006 error recurs, the registration sensor itself might be physically broken.
