These are possible solutions. Try one or more of the following:
Remove the print cartridge.
Make sure the sticker and tape have been removed.
Reinsert the cartridge.
Press to align the cartridge.
For more information, see Aligning print cartridges.
Load only plain, unmarked paper for aligning the cartridge.
The printer will read any markings on used paper, which could cause the alignment error message to appear.
