If print quality does not improve by the standard cleaning of the print head, clean the print head deeply. Cleaning the print head deeply consumes more ink than the standard cleaning of the print head, so clean the print head deeply only when necessary.

You need to prepare: a sheet of A4 or Letter-sized plain paper

1. Make sure that the power is turned on.

2. Load a sheet of A4 or Letter-sized plain paper in the front tray.

3. Open the output tray extension, open the paper output tray, then extend the paper output support.

4. Clean the print head deeply.
(1) Select Setup on the HOME screen.
The setup menu screen will appear.

The Maintenance screen will appear.
(3) Select Deep cleaning, then press the OK button.

The confirmation screen will appear.
(4) Select Yes, then press the OK button.
The machine starts cleaning the print head deeply.
Do not perform any other operations until the machine completes the deep cleaning of the print head. This takes about 1 to 2 minutes.
The pattern print confirmation screen will appear.
(5) Select Yes, then press the OK button.
The nozzle check pattern will be printed.
(6) When the completion message appears, press the OK button.
The screen will return to the Maintenance screen.
