Final Steps Of Reassembly; Troubleshooting Summary - Kodak Instamatic M Series Repairing

Changing the followers provides a very precise fine adjust-
ment for the depth of claw engagement. There is one other
way to adjust the claw engagement—a rough adjustment.
You can loosen the restricting collars, one on each side of
the cam-shaft bearing, Fig. D122. Then shift the cam-shaft
bearing to move the complete in-and-out cam—closer to or
further from the claw. However, it's difficult to position the
in-and-out cam with great precision.
At times, though, you may find that the claw engagement is
so shallow that the film won't advance through the gate. The
reels turn, but the claw can't grab the film. You may then
have to adjust the bearing on the cam shaft until the claw
engages the film. Then use the followers for the fine adjust-
ment to eliminate jumping in the image.

FINAL STEPS OF REASSEMBLY

Once you're satisfied with the operation, again unplug the
projector. Remove the bottom cover. Now slip in the grille
and replace the baffle, Fig. D122. Seat the bottom cover and
replace the screws. Finally, snap the front cover into place.
If the projector takes both super 8 and regular 8, remember
to replace the super-8 adapter over the supply spindle. Also,
before you return the projector to a customer, set the control
to super 8 (most people use super 8 rather than regular 8).

TROUBLESHOOTING SUMMARY

Malfunction: Film does not transport, even though motor
runs.
Likely cause: Shutter gear broken.
Solution: Replace shutter.
Malfunction: Image jumps.
Likely cause 1: Spindles dirty.
Solution: Clean spindles.
Likely cause 2: Insufficient claw engagement.
Solution: Adjust claw engagement.
Likely cause 3: Incorrect claw timing.
Solution: Time shutter cam.
Malfunction: Spindles turn, but the film won't move through
the gate.
Likely cause: Insufficient claw engagement.
Solution: Adjust claw engagement.
Malfunction: Supply reel doesn't turn on rapid rewind.
Likely cause: Rewind driver broken.
Solution: Replace rewind driver.
Malfunction: It's difficult to shift between the running
speeds.
Likely cause: Bushing on cam shaft damaged.
Solution: Replace the bushing.
Malfunction: Still-frame heat-absorbing filter remains in the
light path on the slowest running speed (6fps).

FIG. D123 A projector that runs only super 8
uses the knob-like follower on the left. A
projector that runs both super-8 film and
regular-8 film uses two of the bullet-shaped
followers on the right. Both types come in
different lengths for adjustment.
Likely cause: Snap-ring position on still-mask changeover
rod.
Solution: Adjust snap-ring position.
Malfunction: Still-frame heat-absorbing filter does not
move fully into light path at the still-frame setting.
Likely cause: Snap-ring position on still-mask changeover
rod.
Solution: Adjust snap-ring position.
Malfunction: Shutter does not turn, even though the shutter-
drive shaft turns.
Likely cause: Adjustment on forward/reverse arm.
Solution: Adjust forward-reverse-arm eccentric.
Malfunction: Shutter does not turn when you operate the
projector in reverse.
Likely cause: Adjustment on forward/reverse arm.
Solution: Adjust forward-reverse-arm eccentric.
Malfunction: Excessive noise.
Likely cause: Shutter blade hitting other parts of the projec-
tor.
Solution: Bend the shutter blade for clearance.
Malfunction: Lamp does not turn on.
Likely cause 1: Lamp burned out.
Solution: Replace the lamp.
Likely cause 2: Connections to lamp.
Solution: Check the wire connections to the lamp.
Other possible causes include a defective switch, but switch
failure is unusual.
Malfunction: Motor does not run.
Likely cause 1: Connection between power cord and switch
or between power cord and motor.
Solution: Check, clean, and improve the connections.
