Hello Pam,
I found this article for error 092-651 - ADC Sensor error. For the faded/light printing issue I found some steps that may help you.
My printer will not print using the black ink. It prints very lightly if at all. And it makes a grinding noise coming from the black ink cartridge area. I now have error code 092-651 along with 2880000 Please help! Thank you.
