HP LaserJet 3020 All-in-One Printer - Manual (Page 116)

Misformed characters
● If characters are improperly formed, producing hollow images, the print media that you are
using might be too slick. Try a different media. See
Device media specifications for more
information.
● If characters are improperly formed, producing a wavy effect, the device might need
service. Print a configuration page. See
Printing a configuration page for more
information.
● If the characters are improperly formed, contact an HP-authorized dealer or service
representative. See the support flyer that came with your device for more information
about contacting HP.
Page skew
● Make sure that the media is loaded correctly and that the media guides are not too tight or
too loose against the media stack. See the start guide for information about loading input
trays.
● The automatic document feeder (ADF) input tray might be too full. See the start guide for
information about loading input trays.
● Check the media type and quality. See Device media specifications for more information.
