4.Align the cartridges.

To align the cartridges from the printer software

NOTE: Aligning the cartridges ensures the high-quality output. The printer prompts you to align the cartridges every time you install a new cartridge. If you remove and reinstall the same ink cartridge, the HP All-in-One will not prompt you to align the ink cartridges. The HP All-in-One remembers the alignment values for that ink cartridge, so you do not need to realign the ink cartridges.
