Troubleshooting Tips
Print quality issues: Run two or three Print Head Cleaning cycles from Setup > Maintenance and print a nozzle check.
Ink not flowing: Make sure each bottle is fully seated; the keyed bottle tip releases ink automatically.
Slow printing: Switch quality to Standard rather than Best, especially for 11x17 prints, and confirm the paper type matches what's loaded.
Ink levels look low after refill: Use the LCD menu to manually reset each ink level after a refill.
