Load a few sheets of plain paper in the product.
Press the home button, if necessary.
Select Setup.
Select Maintenance.
Select Head Cleaning.
Press the Start button to clean the print head. You see a message on the LCD screen during the cleaning cycle.
Caution:

Never turn off the product during a cleaning cycle or you may damage it.
When the cleaning cycle is finished, you see a message on the display screen.
Select Print Nozzle Check Pattern, then press the Start button to run a nozzle check and confirm that the print head is clean.

If you don’t see any improvement after cleaning the print head up to 2 times, turn off the product and wait at least 6 hours. Then try cleaning the print head again. If quality still does not improve, one of the ink cartridges may be old or damaged and needs to be replaced.
