The printer will clean the print head nozzles.  Only clean the print heads when the faint areas or gaps appear in your printout.  Use the Nozzle Check utility to confirm that the print heads need to be cleaned.  When the error light is on or flashing, you must replace the ink cartridge before cleaning the print head.
