Dropouts

A single sheet of media might be defective.
Try reprinting the job.

The media's moisture content is uneven or
the media has moist spots on its surface.
Try printing with new media. See

Printer

media specifications

for more information.

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. See

Changing the print cartridge

for more

information.

Note

If these steps do not correct the problem, contact an HP-authorized dealer or service
representative.

Vertical lines

The photosensitive drum inside the print
cartridge has probably been scratched. Install a
new HP print cartridge. See

Changing the print

cartridge

for instructions.

Gray background

Make sure that the single-sheet priority input
slot (Tray 1) is in place.

Decrease the print density setting through
HP Toolbox or the embedded Web server.
This decreases the amount of background
shading. See

Using the hp toolbox

.

Change the media to a lighter basis weight.
See

Printer media specifications

for more

information.

Check the printer's environment. Very dry
(low humidity) conditions can increase the
amount of background shading.
