Y
N
Replace the TM Takeaway Motor
Measure the resistance between the disconnected TM Takeaway Motor connectors
P/J224-1/3/4/6 and the Frame. Is the resistance infinite for all?
Y
N
Check the wires of the pins with non-infinite resistance for peeled-off coatings
and short circuits due to pinching.
Check the connection between the Tray Module PWB
Motor
P/J224
