Common causes

  • 1Dirty, oxidized, or oily copper contacts on the cartridge smart chip.
  • 2Use of a third-party compatible toner with an outdated or blocked chip emulation.
  • 3Mismatched regional SKU on the cartridge relative to the printer's geographical setting.

Solutions

Step-by-Step Technical Instructions

1. Confirm Toner Specifications and Region

  • Verify that you are using genuine Lexmark cartridge codes, such as B224000 or B224H00.
  • If you recently purchased your printer or cartridge abroad, check for regional locking. The chip must match the exact country code setting programmed into your printer's firmware.

2. Clean the Smart Chip Contact Terminals

  • Power down the printer and open the front access door.
  • Remove the toner cartridge from the imaging unit.
  • Locate the copper terminal contacts on the side of the cartridge.
  • Dampen a cotton swab with 90%+ isopropyl alcohol and clean the contacts thoroughly. Ensure no fibers are left behind.
  • Inspect the matching spring-loaded contact pins inside the printer chassis for physical damage or misalignment.

3. Power Cycle and Reset Chip Connection

  • With the toner cartridge still removed, turn on the printer and wait for the 'Toner Missing' prompt on the display.
  • Slide the toner cartridge back in until it clicks firmly into place.
  • Close the front door. The printer will re-interrogate the chip and attempt to clear the 32.01 code.

Steps to follow

  1. 1

    Remove toner assembly

    Open the front cover, release the green lever, and slide the toner cartridge out of the machine.

  2. 2

    Clean copper contacts

    Clean the contacts on the side of the cartridge using an isopropyl alcohol-dampened swab.

  3. 3

    Reinstall and verify

    Firmly push the cartridge back in, close the cover, and restart the printer.
