Clean the printhead
If your printed output is streak ed or has any incorrect or miss ing colors, the printhead might need to
be cleaned.
There are two stages o f cleaning. Each stage lasts about two minutes, uses one sheet of paper, and
uses an increasing amount of ink . After each stage, review the quality of the printed page. You should
only initiate the next phase of  cleaning if the print quality is poor.
If print quality still  seems poor after you  complete both stages of cleaning, try aligning the printer. If
print quality proble ms persist after cleaning and aligning, con tact HP support. For more information,
see 
HP support on page 122.
NOTE: Cleaning uses ink, so clean the  printhead only when necessary.  The cleaning process takes
a few minutes. Some noise might  be generated in the process. Before cleaning the printhead, make
sure you load paper. For more information, see 
Load paper on page 23.

● Make sure that you are printing w
ith paper that is not wrinkled, folded, or damaged.
● Prevent curled or wrinkled paper
 by storing all unused paper flat in a resealable bag.
● Do not use paper that is too thi
ck or too thin for the printer.

ull. For more information, see
Load paper on page 23.

formation on the maximum
number of sheets allowed in the aut omatic document feeder, see 
Paper size and weights
on page 166.
● Do not combine different paper types and paper sizes in the inp
ut tray; the entire stack of paper
in the input tray must be  the same size and type.
● Adjust the paper-width guides in
 the input tray to fit snugly against all paper. Make sure the
paper-width guides do not bend the paper in the input tray.
● Do not force paper too far forward in the input tray.
● If you are printing on both sides of a page, do not print highly saturated images on light weight
paper.
● Use paper types that are recomme
nded for the printer. For more information, see 
Paper size
and weights on page 166.
● If the printer is about to run ou
t of paper, allow the printer to run out of paper first, and then add
paper. Do not try to add paper w hen the printer is trying to pick up a sheet.
