Poor quality printouts
Check the print cartridges
Replace any clogged print cartridges (see Using the print cartridges), 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
Installing or replacing the print cartridges).
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). (For Windows, if the Toolbox is installed, you can find ink-level
information by clicking the Estimated Ink Level tab. For Macintosh, open the ink level panel from
HP Inkjet Toolbox.) If the print cartridge is low on ink, replace it (see
Installing or replacing the print
cartridges).
The print cartridges may need to be cleaned
Perform the auto-clean procedure (see Cleaning the print cartridges).
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.
