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 fails.
If the alignment process fails repeatedly, you might have a defective sensor or ink
cartridge. Contact HP support. Go to www.hp.com/go/customercare. This website
provides information and utilities that can help you correct many common printer
problems. If prompted, select your country/region, and then click Contact HP for
