Strange.  I just had the exact same issue.  Came here looking for an answer.  If I figure anything out, I'll post it here.  Appreciate the same if you do too.

By the way, my Axim just died too.  I'm having a bad Dell day today.  Crossing my fingers my laptop doesn't die next.  It usually comes in threes.

My printer is an AIO 962.  Otherwise, it's the exact same issue. 

Also, I got it without replacing anything.  I had some new cartridges so I tried them too.  No joy.

That darn Right Cartridge Incorrect scrolling across there mocking me is driving me nuts.

In an emergency, this sometimes works.

Go to printer preferences in control panel. select print color in black and white.

This may allow you to print your black and white school work.

Hello, this is the third AIO 962 printer I have been given by Dell. I always have the same problem, "right cartridge incorrect". I have done all necessary troubleshooting steps to no avail. These printers are garbage. I cannot get in touch with anyone at Dell to help me. I have had this problem since 2004. I may smash the printer to pieces, it would be worth more to me...Dell's customer care is pathetic. I am so sorry I purchased a Dell. Should have went with HP. No amount of troubleshooting will get rid of this problem, "right cartridge incorrect". I HAVE HAD IT!

I'm starting to feel the same way about Dell.  I am actually getting an HP printer. I just spent between $50 - $60 on ink that I can't even use now.

You are lucky.  I have had my printer for 15 months so my warranty is expired.  It is ridiculous that Dell won't help me w/o charging me.

This may work for some of the problem printers.

Remove ink carts. Soak print head nozzles on bottom of ink carts in 1/2 inch of hot water for 15 minutes. Blot bottom of ink cart with clean paper towel. You should see the ink colors on the paper towel.

Also wipe electrical contacts on back of ink carts with clean paper towel. An invisible oxcide coating on the contacts can give the readings you see. Replace and retry.

If problem is not corrected, turn off printer, remove AC power cord and USB cable from back of printer for 1 minute. Replug and retry.

Many ink carts including Dells, contain electronics and many micro ink nozzles and pumps. Ink carts can go bad and cause most of these indications. New ink carts can be bad when they arrive new. I doubt if any of the printers are broken. Most of the time the problem is only with the ink carts.
