Check the printer software settings

The printer prints slower when Best or Maximum dpi is selected as the print quality. To increase the print speed, select different print settings in the printer driver. See Changing print settings.

Check for radio interference

If the printer is connected using wireless communication and is printing slowly, then the radio signal might be weak. See Guidelines for reducing interference on a wireless network.

Blank page printed

Check for empty ink cartridges

Check the printer lights to see which cartridge is low (see Interpreting control panel lights). The Toolbox (Windows), HP Printer Utility (Mac OS), and the configuration page (see Understanding the configuration page) provide information about ink levels. If you are printing black text and a blank page prints, the black cartridge might be empty. See Replacing the ink cartridges.

Check the media settings

Make sure you select the correct print quality settings in the printer driver for the media loaded in the trays.

Make sure the page settings in the printer driver match the page size of media loaded in the tray.

Something on the page is missing or incorrect

Check the printheads

Print the print quality diagnostic page on a clean sheet of white paper. Evaluate any problem areas, and perform the recommended actions (see To print the print quality diagnostic page).

Check the margin settings

Make sure the margin settings for the document do not exceed the printable area of the printer. See Setting minimum margins.

Check the color print settings

Make sure Print in Grayscale is not selected in the printer driver.

Check the printer location and length of USB cable

High electromagnetic fields (such as those generated by USB cables) can sometimes cause slight distortions to 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.

Placement of the text or graphics is wrong

Check how the media is loaded

Make sure the media width and length guides fit snugly against the edges of the stack of media, and make sure the trays are not overloaded. See Loading media.
