● A single sheet of media might be defective. Try reprinting
the job.
● The media moisture content is uneven or the media has
moist spots on its surface. Try printing with new media.
● The media lot is bad. The manufacturing processes can
cause some areas to reject toner. Try a different type or
brand of media.
● 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 might correct itself.
● The photosensitive drum inside the print cartridge has
probably been scratched. Install a new genuine HP print
cartridge.
Gray background

● Check the product environment. Very dry (low humidity)
conditions can increase the amount of background
shading.

setting. See
