Poor print quality and unexpected printouts
Check the printheads and ink cartridges
Replace any clogged or worn printheads or low ink cartridges (see Maintaining the
printheads), and try to print again.
Check the paper quality
The paper might be too moist or too rough. Make sure the media used meets HP
specifications (see Selecting print media), and try to print again.
Check the type of media loaded in the printer
z Make sure the tray supports the type of media you have loaded. See Understanding
specifications for supported media.
z Make sure you have selected the tray in the printer driver that contains the media you want
to use. See Changing print settings.
Check rollers in the printer
The rollers in the printer might be dirty, causing lines or smudges to appear on your
printout. Turn off the printer, disconnect the power cord, clean the rollers in the printer with
isopropyl alcohol on a lint-free cloth, and try to print again.
Check the printer location and length of USB cable
High electromagnetic fields (such as those generated by USB cables) can sometimes
slightly distort printouts. Move the printer away from the source of the electromagnetic
fields. Also, it is recommended that you use a USB cable that is less than 3 meters
(9.8 feet) long to minimize the effects of these electromagnetic fields.
