Troubleshooting Tips
Cartridge not recognized: Remove the cartridge, wipe the gold chip with a lint-free cloth, and reinstall it firmly until you hear a click.
Faded or banded prints: Run Head Cleaning two or three times from the printer's Setup > Maintenance menu, then print a nozzle check pattern.
Slow printing: Switch the print quality to Standard instead of Best, and confirm the paper type matches what's loaded in the cassette.
Ink levels stuck: Power-cycle the printer for one minute, then reinstall the cartridges to refresh the chip handshake.
