This could be a hit or miss but what does it hurt to try...
I had this problem with the color cartridge a while back. Worked tirelessly with HP support and somehow got it to work. Since it was on the phone and a while back, I fogot! Now is the time for the black cartridge. Same thing. Reading somewhere here about skipping the test I gave it a try and it worked.

- Unplug the printer for 1 minute (not sure if this is necessary but it doesn't hurt).
- Replug.
- When the "Press Enter to align..." message comes up, PRESS and HOLD Enter.
- While holding Enter, press Menu. The screen skips the test part and shows the date.
- Release Enter. Now you can print. Actually, I could print, you are on your own now.

Good luck!

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

On alignment sheet, do you see a line of yellow blocks?
And on next line do you see alternate block and yellow blocks?

(Without these, alignment fails)

If not, change the colour cartridge, re-print the page and repeat alignment.

Good luck...

It Does keep asking if it fails to get it right, usually it fails to get scan of alignment page completed correctly because it fails to see one of the colours printed on its alignment page correctly,
I would guess that you should change colour cartridge as well (these I have seen deplete themselves trying print black when black ink is not present.

There is also a way of telling your printer to forget about alignment would you like to know how......Press and hold the Setup button, and then press Options (or Copy Options ).

Here is a link to how an alignment page should look and HP answers to your problem, please rate my solution for me.

Try pressing the reset or off button for a few seconds. Failing that, unplug the printer for 15 min. Let me know if it works, if not, then I will guide you through other steps.

well, what i did, and it seemed to work, in the short run anyway. i took and threw my hp in the back of a waste management truck,  then i called amazon.com and i ordered a new epson printer,
