Troubleshooting Tips
Print quality issues: Run two or three Print Head Cleaning cycles from Setup > Maintenance and then print a nozzle check.
Ink not flowing: Make sure each bottle is fully inserted; the keyed bottle tip should release ink automatically.
Slow printing: Switch quality to Standard rather than Best and verify the paper type matches what's loaded.
Ink levels look low after refill: Press the i info button to manually reset the ink levels after refilling.
