Locate motors M1, M2, M16, M17, and M18:
•
Raise the Lid and insert a cheater into the Interlock.
•
Motors M1 and M2 are located on the rear side of the bypass
transport assembly (PL 5.3). Motor M1 drives the input side Belt,
while Motor M2 drives the output side Belt.
•
M16, M17, and M18 are located on the Steering Subassembly

skew adjustment. Motor M18 drives the Steering Subassembly
for alignment adjustment.

the Interlock Cheater is inserted. See Section 0, page vii
