Dell 924 all in one...have had this printer cartridge for weeks now, used it to print 30+ pages about three hours ago...now says unsupported cartridge. Sees black cartridge but not color.....any suggestions?

the trick is to use an empty color cartridge.

Since you are printing occasionally, I guess the nozzles on your print head (which is on your cartridge), are clogged up. You can find your printer on your pc, or just click print. When the window for printing opens, you will see several tabs. One of them should be "maintenance". You can try and clean the nozzles via your pc. Just follow the instructions on your monitor. You should also know that cleaning the nozzles will use a lot of your ink, especially if you do it several times.
Hope that helps!

This can happen to cartridges with attached print heads such as HP, Lexmark or Dell. All cartridges are weighed and tested before leaving the factory so lack of ink isn't the problem. It usually has to do with the print head of the cartridge not having any ink to feed it. This happens because cartridges are kept flat or upside down for weeks or months before being used and the ink settles away from the print head. The easiest remedy is to open the box and stand the cartridge upright for a few minutes before using. Then get a damp paper towel, fold it into quarters and sit the cartridge print head down onto it. Hold the cartridge down to the damp paper towel for three minutes. This will help pull the ink out of the print heads, priming them and getting them ready to print. Finally, install the cartridge into your printer and print a few test pages.

threw the SOB away

I have the same issue where the printer displays "Right cartridge Incorrect". However, it's had no problems up until about two weeks ago and I've had the right cartridge in place for about a year or so.

Printer: AIO 922 (All-In-One 922)
Ink: Remanufactured ink

You can't have a Dell cartridge refilled. It's Dell's way of making big bucks selling overpriced cartidges. Their practise is almost illegal and eventually they will get sued.
Buy an HP or a Kodak printer. Both sell better printers and their cartidges can be refilled.

clean the contact on the printer and the ink cartridge. do not use paper towel. use coffee filter.

Check to make sure that all of the packing "tape" has been removed correctly on the replacement cartridge and that the cartridge is seated correctly and the circuit contacts make good contact with the contacts within the carriage assembly and that nothing is obstructing it. Possibly a defective cartridge..

Try replacing the cartridge with a new Dell ink cartridge, the refill may have gone bad.

I refilled color ink for Dell Photo 924 but some reason it showing it me low ink.
