Hello aub1,
Welcome to the HP Forums!
I understand the Photosmart C5280 is stuck on "Now printing alignment". I will do my best to assist you! Please follow this HP document on Alignment Page Does Not Print.Make sure this printer is plugged into a direct wall, not a surge protector. Try resetting the printer for more than 60 seconds, then try printing a alignment page.
If this step doesn't work, then let's try another reset:
1) Take out all your ink cartridges, close the door
2) Unplug the power cord for 60 seconds, then plug it back in
3) Wait for the printer to turn on completely, then install the ink cartridges
4) Next, try to print an alignment page
Please post your results!
