Quick Diagnosis

If your printer display shows the 31-01 error, the system is struggling to identify the installed toner. Often, this is a simple connection issue between the cartridge contacts and the machine's internal pins.

Step-by-Step Solution

  1. Remove cartridge: Open the front door and slide out the toner cartridge.
  2. Clean chip: Use a soft, dry cloth to clean the gold chip on the toner and the machine's contact interface.
  3. Reinsert: Firmly push the cartridge back in until it is securely seated.
  4. Cycle Power: Restart the device to initiate a new cartridge detection check.

Prevention and Maintenance

Avoid placing your fingers on the electronic chip of the toner cartridges. Regular dust removal inside the print bay helps keep the contact interface free of debris.
