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.

1. Make sure that the power is turned on.

2. Make sure that one or more sheets of A4 or Letter-sized plain paper are loaded in the Cassette.

3. Open the Paper Output Tray gently, and open the Output Tray Extension.

5. Examine the nozzle check pattern.
