Routine Maintenance
Print Head Cleaning
Clean the Print Head if lines are missing or if  white streaks appear in the printed nozzle check

ink, so perform Print Head Cleaning only when necessary.

the Output Tray Extension.
2Load a sheet of A4 or Letter-sized plain paper in the Rear Tray or the Front Tray.

Cleaning, so perform this procedure only when necessary.

the Output Tray Extension.
