Vertical repetitive defects

occurs at the same spot on the page, install a new
HP print cartridge. See
Replace the print cartridge

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.
Misformed characters
● If characters are improperly formed, producing hollow
images, the media stock might be too slick. Try a different
media. See
Supported paper and other media
on page 21 .
● If characters are improperly formed, producing a wavy
effect, the device might need service. Print a
configuration page. If the characters are improperly
formed, contact an HP-authorized dealer or service
representative. See
