Vertical repetitive defects
●
The print cartridge might be damaged. If a repetitive mark
occurs at the same spot on the page, install a new genuine
HP print cartridge.
●
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.
●
In the printer driver, make sure the appropriate media type
is selected.
Misformed characters
●
If characters are improperly formed, producing hollow
images, the media stock might be too slick. Try a different
media.
●
If characters are improperly formed, producing a wavy
effect, the product might need service. Print a configuration
page. If the characters are improperly formed, contact an
HP-authorized dealer or service representative.
Page skew
●
Make sure that the media is loaded correctly and the media
guides are not too tight or too loose against the media
stack.
●
The input bin might be too full.
●
Check the media type and quality.
Curl or wave
●
Check the media type and quality. Both high temperature
and high humidity cause media to curl.
●
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 the printer
driver, make sure that 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.
