Cleaning the printhead nozzles

If you have not been using the printer for a long period, then you may need to clean the printhead nozzles to improve the quality of your prints. Keep your printer plugged to a properly grounded, working electrical outlet to allow it to perform automatic maintenance cycles.

Notes:

•Cleaning the printhead nozzles uses ink, so clean them only when necessary.

•Deep cleaning uses more ink, so try the Clean Printhead option first to save ink.

•If the ink levels are too low, then you must replace the ink cartridges before you can clean the printhead nozzles.

1From the printer control panel, navigate to: > Setup > OK > Maintenance > OK

2Press the up or down arrow button to scroll to Clean Printhead or Deep Clean Printhead, and then press OK .

3Press the up or down arrow button to scroll to a cleaning option, and then press OK . Wait until the printer is ready.
