Dell All-in-One Printer Cartridge Error 1203.
I found if you cover a
copper contact on the color cartridge the error clears and the cartridge
works. Looking from the contact side for the color cartridge 2nd row
contact 2 from the left. I found if I use an ohm meter from 2nd to 3rd
contact I measure 119 ohms. I believe that is a shorted cartridge. If
you bought it New I would get it replaced. I use a SMALL square piece of
Scotch tape.
