      Samir: No, not again. I... why does it say paper jam when there is no paper jam? I swear to God, one of these days, I just kick this piece of shit out the window.

              The sensors are all monitored by the DF Control PCB. I would start by re-seating all the connectors on the DF control PCB and tracing the wires from the sensor to the board checking for pinches or shorts.

              Do you have 5v at the sensor? Yeah I know, practically no one likes to use a meter anymore...but us old time techs know....Voltage never lies.

              Next the signal goes through an interface, reseat the connectors there. Check your harness to the copier for bent pins or damage.

              From the interface board the signal goes to the main frame...I'm too sleepy right now to pull out the P2P to see where it goes from there....Probably to the BICU.

              Attaching the DF control overview...

              Relax! This firmware injection won't hurt...but it will take 45 minutes.
