Clean the product on page 123.
Image defect table

Light print or faded
NOTE:
The paper might not meet Hewlett-Packards media
specifications (for example, the paper is too moist or too
rough).
1. If the whole page is light, the print density...

Dropouts
●A single sheet of paper might be defective. Try reprinting
the job.
● The media moisture content is uneven or the paper has
moist spots on its surface. Try printing with new paper.
● The paper lot is bad. The manufacturing processes can
cause some areas to reject toner. Try a different type or
brand of paper.
● The print cartridge might be defective. Install a new
genuine HP print cartridge.
Vertical lines
●Toner might be on the photosensitive drum. Print a few
more pages to see if the problem...

Loose toner
●The fuser temperature might be too low. In the printer
driver, make sure the appropriate paper type is selected.
● Clean the inside of the product. See 
Clean the product
on page 123
.
● Check the paper quality.
● Plug the product directly into an AC outlet instead of into
a power strip.
Vertical repetitive defects
●The internal parts might have toner on them. If the defects
occur on the back of the page, the problem probably will
correct itself after a few more printed pages.

Curl or wave
●Check the paper type and quality. Both high temperature
and high humidity cause paper to curl.
● The paper might have been in the input tray too long. Turn
over the stack of paper in the tray. Also, try rotating the
paper 180° in the input tray.
● The fuser temperature might be too high. In the printer
driver, make sure that the appropriate paper type is
selected. If the problem persists, select a paper type that
uses a lower fuser temperature, such as transparencies
or light paper....

cooling. The heat and moisture generated by the printing
process escape through vents in the product exterior or
through the output bin area.

However, HP recommends using the following steps to verify
that the product is releasing steam and does not have a
functional problem.
1. Turn the product off, and then on.
