Troubleshooting Cartridge Recognition Issues

If your HP LaserJet Pro M402n printer is not recognizing the cartridge, try powering off the printer and unplugging it from the power source for a few minutes. This can help reset the printer’s system and may resolve the recognition issue.

Check the cartridge to ensure it is properly installed and compatible with your printer model. Sometimes, cartridges may not be fully seated or may be the wrong type for your printer.

If the issue persists, update your printer’s drivers to ensure compatibility with your computer’s operating system. This can often resolve recognition issues and improve overall printer performance.

Additionally, clean the cartridge contacts with a lint-free cloth to remove any dust or debris that may be interfering with recognition. Proper maintenance can help prevent future recognition problems.
