Additionally, I filled the light black cart with the remaining ink I had as it was getting low. Now I cannot get the printer back working again.
Panel shows an X and missing cart error. I unplugged all the carts but no difference. I check whether I had the control chips in properly for the 2 new carts and all was well. Printer shows all carts being full even though they are not.
I pulled the maintenance cart out as well in desperation. No go. I rebooted several times including unplugging. Same error.
