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:
z Check the health of the printheads
z Initiate the automatic printhead cleaning process
z Manually clean the printhead contacts
z Replace the printheads, if the problems persist after cleaning.
CAUTION HP is not responsible for damage to the printer that results from modifying the printheads.
