Poor quality printouts
Check the print cartridges
Replace any clogged print cartridges (see Using the print cartridges on page 19), and try to print
again.
The printer may be in Ink-backup Printing Mode
The printer enters Ink-backup Printing Mode when one of the print cartridges is empty or removed.
Replace the missing print cartridge with a new one (see
Inserting the print cartridges on page 20).
Verify the ink levels of the print cartridges
One of the print cartridges may be low on ink. To view the ink levels, print a diagnostics page (see
Printing a diagnostics page on page 83). (For Windows, if the Toolbox is installed, you can find ink-
level information by clicking the Printer Status tab. For Macintosh, open the ink level panel from
HP Inkjet Toolbox.) If the print cartridge is low on ink, replace it (see
Inserting the print cartridges
on page 20).
The print cartridges may need to be cleaned
Perform the auto-clean procedure (see Cleaning the print cartridges on page 22).
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 on page 27), and try to print again.
