Adjust Print Quality : Clean the Print Head

Clean the Print Head Nozzles
If print quality has declined and the nozzle check pattern indicates clogged nozzles, you can clean the print head.
Note:
You cannot clean the print head if an ink cartridge is expended, and may not be able to clean it when a cartridge is low. You must replace the cartridge first.
