Improve print quality
1. Make sure you are using genuine HP cartridges.
2. Check the print properties to make sure you have selected the appropriate paper type and print quality from
the Media drop-down list. In the Printer Software, click Print and Scan and then click Set Preferences to
access the print properties.
3. Check the estimated ink levels to determine if the cartridges are low on ink. For more information, see Check
the estimated ink levels . If the print cartridges are low on ink consider replacing them.
4. Align the printer cartridges
To align the cartridges from the Printer Software
NOTE: Aligning the cartridges ensures high-quality output. The HP All-in-One prompts you to align the
cartridges every time you install a new cartridge. If you remove and reinstall the same print cartridge, the
HP All-in-One will not prompt you to align the print cartridges. The HP All-in-One remembers the
alignment values for that print cartridge, so you do not need to realign the print cartridges.
