Solutions

Quick Diagnosis

If 32.02 appears after a new toner install, dirty contacts are likely the cause. If it happens with old toner, the chip may have failed.

Step-by-Step Solution

  1. Re-seating: Open the front cover and pull the toner, then reinstall ensuring a firm click.
  2. Contact Cleaning: Clean the metal pins on the cartridge with a dry, lint-free cloth.
  3. Power Reset: Turn off the printer for 10 seconds to prompt a fresh scan.

Prevention and Maintenance

Do not touch cartridge circuitry, as skin oils can obstruct data reading. Stick to original Lexmark supplies for better compatibility.
