on the driven motor pulley. While removing the
transfer shaft, be careful not to misplace the
nylon washer between the film feed drive pulley
and the left bearing plate and the nylon washer
between the middle frame plate and the platen

6. Remove the front finger plate from the
machine. Do not pull the plate away from the
machine too quickly, as the photoelectric
eye is attached to the plate and wired to the
machine. Gently place the plate under the
rollers, ensuring the sensor wire is not
excessively pulled (Figure 3-162).
