The Lexmark MS431dw error 32.01 is a warning indicating a communication fault between the printer and the installed toner cartridge.

Solutions

Diagnostic quick-check

If the device displays 'Cartridge not recognized' alongside code 32.01, the issue is almost certainly an electrical contact fault. Check if the toner moves slightly when touched; if it does, it is not properly secured.

Step-by-step solution

  1. Power off the printer and open the front hatch.
  2. Remove the toner and drum unit.
  3. Inspect the gold metal contacts on the cartridge for residues or fingerprints.
  4. Clean gently with a lint-free cloth.
  5. Reinsert the cartridge firmly until it snaps into place. If the problem persists, try a replacement cartridge.

Prevention and maintenance

Always handle consumables by the sides. Keeping the printer interior free of toner dust helps the recognition sensors work more efficiently.

When to call a technician

If you have tested two different cartridges and error 32.01 persists, it is possible that the internal sensor or the cable connected to the board is damaged.
