Maintaining the printheads
If printed characters are incomplete, or dots or lines are missing from printouts, this may be caused by clogged ink nozzles and you might need to clean the printheads. To find out which printheads work with your printer, see Supplies.
When the quality of printouts deteriorates, complete the following:
zCheck the health of the printheads
zInitiate the automatic printhead cleaning process
zManually clean the printhead contacts
zReplace the printheads, if the problems persist after cleaning.
CAUTION | HP is not responsible for damage to the printer that results from modifying the printheads. |
