If the printer displays 'Cannot Detect', note which color is affected. Check for ink spills on the metallic chip contacts; even a microscopic smudge can break the electrical connection.

Solución paso a paso

  1. Remove the problematic cartridge and inspect the chip for visible smudges or oxidation.
  2. Clean the gold contacts on the cartridge and the printer's internal contact pins with a dry, clean cloth.
  3. Re-insert the cartridge, pressing firmly until you hear a mechanical click.
  4. Power cycle the printer by unplugging it for 30 seconds to force a system re-read of the cartridges.

Prevención y mantenimiento

Avoid touching the gold chips on new cartridges with your fingers to prevent skin oils from interfering with connections. Ensure you are using region-specific cartridges for your MFC-J1170DW.
