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

zMake sure the tray supports the type of media you have loaded. See Understanding specifications for supported media.

zMake 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.
