●
The print cartridge might be damaged. If a repetitive mark
occurs at the same spot on the page, install a new HP print
cartridge. See
for instructions.
●
The internal parts might have toner on them. See
for more information. If the defects occur on the back of
the page, the problem will probably correct itself after a few more
printed pages.
●
In your printer driver, make sure the appropriate media type is
selected.
●
If characters are improperly formed, producing hollow images,
the media stock might be too slick. Try a different media. See
for more information.
●
If characters are improperly formed, producing a wavy effect, the
printer might need service. Print a configuration page. If the
characters are improperly formed, contact an HP-authorized
dealer or service representative. See
for
more information.
●
Make sure that the media is loaded correctly and the media
guides are not too tight or too loose against the media stack. See
for more information.
●
The input bin might be too full. See
for more
information.
●
Check the media type and quality. See
for more information.
●
Check the media type and quality. Both high temperature and
humidity cause media to curl. See
for more information.
●
The media might have been in the input tray too long. Turn over
the stack of media in the tray. Also, try rotating the media 180° in
the input tray.
●
The fuser temperature might be too high. In your printer driver,
make sure the appropriate media type is selected. If the problem
persists, select a media type that uses a lower fuser
temperature, such as transparencies or light media.
