HP 7200 - Manual (Page 176)

remembers the alignment values for that print cartridge, so you do not
need to realign the print cartridges.
I received a message on the control panel display that the print cartridge
alignment failed
Cause The incorrect type of paper is loaded in the input tray.
Solution If you have colored paper loaded in the input tray when you align the
print cartridges, the alignment fails. Load unused plain white letter or A4 paper
into the input tray, and then try the alignment again. For more information, see
Align the print cartridges .
If the alignment fails again, you might have a defective sensor or print 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.
Cause Protective tape is covering the print cartridges.
Solution Check each print cartridge. If the plastic tape is still covering the ink
nozzles, gently remove the plastic tape by using the pink pull tab. Do not touch
the ink nozzles or the copper-colored contacts.
1 Copper-colored contacts
2 Plastic tape with pink pull tab (must be removed before installing)
3 Ink nozzles under tape
Reinsert the print cartridges and verify that they are fully inserted and locked in
place, and then try the alignment again. For more information, see

cartridges .
