Keep getting message Press Enter to Align Cartridges

Press menu and then press the Right Arrow key until you get to maintenance screen then press enter.
Option 2 is you align print cartridges.
Automatic cartridge alignment
Perform the following steps to align the ink cartridges:

1. Disconnect the power cord from the unit, wait five seconds, and then plug it back in. This will reinitialize the unit.
2. Print another alignment test page. If the Press Enter to align message is not currently on the front panel display, complete the following steps to print an alignment page:
1. Press Setup or Menu on the front panel (depending on the model).
2. Press the right arrow button (>) until Maintenance or Tools is displayed, and then press Enter or OK (depending on the model).
3. Press the right arrow button (>) until Align Print Cartridges is displayed, and then press Enter or OK (depending on the model).
3. To determine if the automatic alignment is functioning correctly, look into the output tray as the alignment page is printing; a blue light should be visible periodically on the page as the cartridges move back and forth. If this light is not visible, the product will not be able to align the cartridges and will require service. Service the product.
4. If the blue light is visible and the alignment pages are printing correctly, but the alignment pages still fails, there still may be a hardware problem with the unit.
If there are no other printing problems and you wish to continue, use the information in the Bypassing the ink cartridge alignment section below to bypass the alignment. The information from last successful alignment will be used.
If the message keeps reappearing or other print quality problems occur, service the product.

from user manual::
To align newly installed print cartridges
1. Make sure you have letter or A4 unused plain white paper loaded in the input tray.
The HP All-in-One prints a print cartridge alignment sheet.
NOTE: If you have colored paper loaded in the input tray when you align the print cartridges, the alignment will fail. Load unused plain white 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.
Contact HP Support. Go to www.hp.com/support. ....
2. Load the print cartridge alignment sheet print side down on the left front corner of the glass with the top of the page to the left.
3. Press the Scan button.
The HP All-in-One aligns the print cartridges. Recycle or discard the print cartridge alignment sheet
Score the solution and download the manual if you need it

Try the following button sequence on the front panel of the printer :

Press and hold the Setup, button, and then press Options (or Copy Options).

This means one of the cartridges is defective, they cant align if they cant print.  What i did to fix this problem is insert 2 working cartridges and get it to align properly, even if they are low on ink, then lift the cover and the cartridges will move to the center.  When this happens pull the power cable out, then insert the full non functioning cartridge. Plug the power cable back in.  I tried this with a color cartridge, the color cartridge was non functioning but i was able to print in black.
Basically you align the cartridges and then swap them so the printer thinks they are still aligned.
The color still doesnt work and it is probably a defective color cartridge.

You can also bypass the alignment. When the message for alignment displays on the display => Press Setup and Options (or Copy Options ) simaltanious.The last known alignment is used when the alignment is bypassed.

PRESS SET UP & OPTIONS AT THE SAME TIME. WILL CLEAR MESSAGE.

Drop ithe 2210 from the 10th floor of a 22 story building. Problem solved. No more repetetive error !!!

I have an OfficeJet 5780 and I have to do the alignment also. The allignment page it prints should have instructions on it. Just put it in the scanner and press "Enter". It needs to scan it to align the print heads.

This is from the manual on their website:

The HP Officejet prompts you to align cartridges every time you install or
replace a print cartridge. Aligning the cartridges ensures high-quality output.
To align the print cartridges when prompted:
1 Press Enter on the front panel.
An align cartridges (test pattern) page prints.
2 Load the align cartridges page face down in the ADF between the paperwidth
guides and press the Enter button again.
3 Recycle or discard the page.

There is no doubt in my mind it Will be the cartridges you are using, alignment will continue to be requested if print out is missing bits do yourself a favour and use HP gen., not trying to plug HP just telling you the facts
