Kyocera/Copystar DP-772 document feeder: not working: Fits others listed.

Description

Was working perfectly. Machine is being parted out. I had removed feeder to take these pictures. when i reinstalled it it locks into "Scanning originals" after it finishes scanning and will not run again until power off/of. Simulation code 244 shows lower level tray sensor is actuated. I do not want to work on it and will sell it as is. Hopefully a Kyocera tech who knows the machine will be able to fix it or use it for parts. It was working beautifully and the machine had 331,000 prints and 116,000 scans before this happened. removed from a working Kyocera 4501i. In addition to the 4501, it fits the 2551ci, 3051ci, 3010i, 3051ci ,3500i, 3501i, 3551ci, 4500i, 4551ci, 5501i, 5551ci.
It appears that shipping cost will be roughly to northeast up to about 0 for west coast.
This is a dual scan document feeder. The original document passes through the feeder and both sides are scanned at the same time.
This complete working machine will be parted out separately: fuser, HDD, etc.
