To make the adjustment:
1. Be sure the transfer belt unit is installed correctly and the 6
mounting screws are tight.
2. Insert an allen wrench into the hole in the offset collar. Use the
wrench as a lever to rotate the collar clockwise or counter-
clockwise and adjust belt tracking. Rotate the collar one click at
a time and recheck the adjustment. Adjust for minimum
clearance at the front, left corner of the belt unit without the belt
tracking against the right stopper.
