I have an MPC2550 that jams when feeding from tray 2. Paper stops at the sensor just past the first set of transport rollers every time. The following parts were replaced by another technician but has yet to fix the problem. (BICU, Driver board, Wrap Clutches, Sensor, Gear/Motor assembly, paper guide, and paper feed unit.) I have verified the sensor changes state with input checks. Verified feed is working with output check. Today I updated all the firmware and ran an engine memory clear. Also reseated all the connectors to both boards. At this point I suspect the problem is more to do with logic than mechanical malfunction. Plan on replacing the BICU NVRam as my next step. Anyone ever run into this same issue?
