FIG. D118 M80 projector transporting film.
Bring the film from the supply reel across the damping arm.
Push down the damping arm until it latches. Then feed the
film through the top of the gate. When you turn on the
projector, the film should advance through the gate and
automatically wrap around the take-up reel. The damping
arm should disengage and move up, providing a loop of film.
Fig. D118 shows the film path through the projector.
Turn on the lamp and check the projected image. Can you
detect any jumping in the image? You can more easily detect
jumping by turning the frame control until you can see the
line between the frames. The line should appear steady
without jumping.

film.
If the image does jump, there are a couple of possible
problems. Does the image jump just on super 8? Or just on
regular 8? If the image jumps on one but not the other, you
may have to adjust the claw engagement (see the following
topic). But if the image jumps on both regular 8 and on super
8, the problem may be dirt in the spindle.
You might try drawing some film from the supply reel to see
if the jumping stops—that way, the film moves through the
gate without being held back by jerky movement in the
supply spindle. If the jumping does stop, try cleaning the
spindle. As the projector is running, spray the cleaner/
degreaser into the spindle as shown in Fig. D119. Hold the
spindle while you're spraying in the solution. Then use your
compressed air to blow out the cleaner.
Also check image while running the projector in reverse.
Again, the image should not jump. If the image does jump,
