Cleaning the print cartridges
If printed characters are incomplete, or if dots or lines are missing from the printouts, you might need to
clean the print cartridges. These are symptoms of clogged ink nozzles, which can result from prolonged
exposure to air.
NOTE: Before you clean the print cartridges, make sure the print cartridge ink levels are not low or
empty. Low ink levels can also cause incomplete characters, missing lines, or dots on the printouts. Check
the print cartridge lights to make sure they are not on. (See
Printer lights reference .) You can also check the
status of the print cartridges from the Printer Status tab in the Toolbox (Windows) or HP Printer Utility
(Mac OS). Replace any low or empty print cartridges. For instructions, see
Replacing the print cartridges .
If you are using a Pocket PC or Palm OS device, you can use the Toolbox software for PDAs. See Toolbox
software for PDAs (Pocket PC and Palm OS) .
To clean print cartridges automatically
NOTE: Clean the print cartridges only when necessary. Cleaning uses ink and shortens the life of the
