Deskjet 9800 cartridge error
Hello! I have one of those, and we've discovered others having a similar problem. In both the 9800 & 6800, there is a spring on the side of the cartridge housing of the PCB. At times, when putting in a new cartridge, that spring comes loose. If the clip feels forced, the spring came loose & the tip of that spring will prick the ribbon cable on the rear of the PCB housing. When doing so, it displaces the ribbon cable just enough to leave an open circuit with the cartridge.
I solved this problem by sliding the tip of a flexible plastic object (like a wire harness) behind the ribbon cable, then mildly forcing in the cartridge. This reset the position of the ribbon cable to close the circuit with the cartridge.
Hope this helps. Good luck!
