Align cartridge
The product prompts you to align ink cartridges every time you install or replace an ink cartridge.
You can also align the ink cartridges at any time from the product’s control panel or by using the HP
software installed with the product. Aligning the ink cartridges ensures high-quality output.
NOTE: When you remove and reinstall the same ink cartridge, the product remembers the
alignment values for that ink cartridge and does not prompt you to align the ink cartridge.
If the alignment process fails, make sure you have loaded unused, plain white paper into the input
tray. If you have colored paper loaded in the input tray when you align the ink cartridges, the
alignment will fail.
If the alignment process fails repeatedly, you might have a defective sensor or ink cartridge. Contact
HP support. Go to www.hp.com/support. If prompted, choose your country/region, and then click
Contact HP for information on calling for technical support.
For more information, see Align the ink cartridges.
