FILM FEED ROLLER DRIVE BELT (con’t)
4. Loosen the two set screws on the pulley on the
transfer shaft (Figure 3-155). This will allow
the pulley to slide on the transfer shaft. Also
loosen the clamping collar located next to the
middle frame plate. (Note: if the model SX
is
equipped with a printer, the platen roller drive
pulley set screws will also need to be loosened
to allow the transfer shaft to slide. This pulley
is the substitute for the clamping collar. Refer
to Figure 3-155 for details.)
5. Remove the transfer shaft by pulling outward
on the driven motor pulley. While removing the
transfer shaft, be careful not to misplace the
two nylon washers on the transfer shaft: one
between the film feed drive pulley and the left
bearing plate and one between the collar clamp
and middle frame plate. These washers act as
spacers for proper belt alignment. (Note: if the
model SX
is equipped with a printer, the
collar clamp will be substituted with the platen
roller drive pulley on the transfer shaft. It will
also have a nylon washer located between the
pulley and the middle frame plate.)
6. Replace the belt, putting it on the roller pulley
first. Place the transfer shaft pulley inside the
belt, and reinstall the transfer shaft.
Do not
forget to reinstall the nylon washer.
(Note: if
the model SX
is equipped with a printer, also
align the transfer shaft with the platen roller
drive pulley and the second nylon washer.)
7. Press the transfer shaft pulley tight to the nylon
washer. Perform a quick visual inspection to
ensure the pulleys are aligned.
8. Once pulleys are aligned, tighten the set
screws to locate the pulley(s) on the transfer
shaft. The shaft has 2 flat areas 90° apart for
the set screws to seat on.
Be sure the set
screws are tightened onto the flat areas of
the transfer shaft
(Figure 3-157). Also tighten
the clamping collar once it is moved tight to the
nylon washer by the middle frame plate. This
will capture the transfer shaft to prevent
movement during operation.
