Need alignment or 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. If the alignment fails again, you might
have a defective sensor or print cartridge.
