Clean the printheads
As long as the printer is kept turned on, an automatic cleaning is performed periodically. This ensures there is fresh ink in the nozzles and prevents nozzle clogs, which ensures color accuracy. If you have not already done so, please see The Image Diagnostics Print on page 172 before proceeding.
To clean the printheads, press the Menu key to return to the main menu and select the Image Quality
Maintenance menu icon 
, then Clean printheads. If you have gone through the Image Quality Diagnostic print process, you know which colors are failing. Select the pair of printheads which contain the failing colors. If you are not sure which colors to clean, you can also select to clean all printheads. Cleaning all printheads takes about nine minutes. Cleaning a single pair of printheads takes about six minutes.
NOTE: Cleaning all printheads uses more ink than cleaning a single pair.
If you have cleaned the printheads using the Clean printheads procedure from the front panel and are still experiencing image quality problems, you can try cleaning the printhead nozzles manually using the following procedure.
CAUTION: This is a delicate process and may damage the printhead. Do not touch the electrical connections on the backside of the printhead.
