Clean 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. For more information, see
Control-panel lights reference
. You can
also check the status of the print cartridges from the Printer Status tab in the
Toolbox (Windows), HP Printer Utility (Mac OS), or Toolbox software for PDAs.
Replace any low or empty print cartridges. For more information, see

NOTE: Clean the print cartridges only when necessary. Cleaning uses ink and
shortens the life of the print cartridges. There are three levels of cleaning available.
After one level of cleaning, perform the next level of cleaning only if the results are
