One of my customer's has a Sharp AL-1655CS that had the delivery assembly quit working on him. After trying the motor and checking the belts and bushings, I replaced the main PCB with one from an AL-1651CS parts machine. The copier now works fine except the 1651 only has a single tray so the board won't recognize the lower cassette. Do any of you guys have the part number for the AL-1655CS main PCB so I can order it from my local Sharp dealer? Thanks again, Chris
