HP 722C color printing problem

I have a HP 722C printer that will only print black and magenta. It is supposed to print black, Magenta, yellow and cyan .
 When it first happened I replaced the cartridge and the same thing happened. I then did a cleaning all the way through prime with the same results. I then returned the cartridge and got anothe one. Same results. I then uninstalled the driver and re-installed. Same results. I've had this printer since September 18, 1998 which came with my Dell computer. Dell doesn't warrant third party hardware and the HP warranty has run out. Does anyone have a suggestion?

Those are the colors in the cart that the printer mixes to make colors. Check your cable and try deleting the printer and reinstalling but you may have an internal problem in the printer not processing the color signals

As I stated in my question I have already uninstalled my driver and reinstalled it. I was hoping that maybe there was something I had missed besides an internal problem with the printer as repair would probably cost more than the printer it self. Thanks for the comment.
We ran into this....the properties on our printer driver were set to "print in grayscale". Have you checked this...when it happened to us, we didn't actually set the setting...it was set when the driver was installed or ?.
Thanks for the comment. The driver is set for color and had been working up until a week or so then according to my wife the colors started to have a magenta look and after a few days that's all it had. Figured cartridge ran out of ink and replace but same problem. Replaced again and same problem. Look like an internal problem unless I'm missing something. Thanks again.

Brian,

Thanks for the comments. I tried everything you said but no help. I finally decided to call HP and suck up the charge. After listening to my story and trying a few things they took off the charge and are going to send me a new black and color cartridges to try just in case even though I told them that the cartridges I had were purchased at different times. As long as they are paying for it I have no complaint. Also to check out the printer by it self, you disconnect the interface cable and while the printer is on you press the Power key and then press the   Resume Printing key which is just below the power key four separate times and release the power key. It should print out the primary colors. Mine prints out just black and magenta.

I don't have a photo setting for my driver. The setting I have are economy, normal, and best.

If you want I'll let you know what happens when I get the new cartridges. Send me a message if you would like to know. Thanks again for the thourgh reply. I really appreciate it.
sure let me know what happens and thanks for the info. on how to do the color print it has been awhile since i did one on one of these printers.... the last time i did a self test print on an hp was holding the resume and powering it on.
Brian,

Well, I got the cartridges from HP and now I've got color again. Hard to believe the luck of getting two bad cartridges and two different times. HP agreed to give me another cartridge for the one I still have and I have to send them the bad cartridges so they can study them and try to figure out just exactly what happened. Thanks for your help.
Glad it worked i know it is hard to believe i have run into as amny as 3 in a row that were bad they are shipped in lots to the stores the stores do not store them properly half of the time... which causes one of the problems right there... if they do store them properly but a lot that was manufactured is bad then most likely at least 50% of that stores supply is bad if they got a bad lot... if not all of them... the cartridges were probably underfilled (not enough ink put in them)  or the printhead on the end was defective.
