HP Deskjet 6940 Series Printer: I'm on my second brand new color cartridge for this printer. The printer simply doesn't recognize that the cartridge is installed. Sometimes the color cartridge light blinks, I remove and re-insert the cartridge, and it stops blinking. It will only print black and white. Any suggestions?

SOURCE: will not print at all

You can try restoring the printer to factory settings..and try agian it has worked most of the times for me..Let the catridge be in the printer when you do this..

Pop out the cartridge and look inside the printer where the black cartridge goes. There may be punctures in the ribbon cable from the metal wire that rests against the catridge. I have lost 2 6940's to this problem.

SOURCE: HP Deskjet 6940 not printing after replacing ink cartridge

My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected

SOURCE: The printer doesn't recognize the new original HP color cartridge

There is a small spring that holds the ink cartridge in the ink holder. You will see it stick out from the right hand side of the ink holder where the ink cartridge slides in. If that spring isn't being held to the ink holder by two plastic tabs, (I.E. the plastic tabs are broken) the printer will never recognize the cartridge. If the printer is still under warranty I would contact HP or an authorized repair center for HP. Both the black and color ink holder has this spring. I know of no way to repair this kind of breakage.
