8MM-16MM FORUM WORLDWIDE

Hi All

This is my first post and I have a problem to solve.

I'm looking for help to repair a projector I have inherited. After investing in new belts, fuses and a new lamp I have discovered the real fault with this unit. Firstly you can see the model I have by going here

OK, the fault is with the framing, which causes the film to jump up and down. The frame control doesnt fix it nor does pressing on the loop former. When switching to reverse play it will hold the frame good for about 5 seconds and than start jumping again.

I am hoping it is just an adjustment that needs to be made. But where?

Trouble is I dont know where to start, maybe someone can tell me where to check or look for.

John, welcome to the forum.

The problem sounds like the claw is not engaging the perforations in the film. If the claw doesn't go deep enough into the perfs, what you are describing could happen. With the projector unplugged you might be able to open the bulb compartment and look behind the aperture plate and see the claw arm. If you can see it you could give a light push forward towards the front and then plug the projector in and try a test film. Just remember, don't reach in there while the projector is on because the shutter may be turning and could cut your finger.

Thanks but Ive fixed it!


While in the process of removing the panels, I discovered that the grub screw which fastens the framing knob to its spindle was not tight enough. It gave the impression that it was OK but it was just scoring a groove on its spindle. Solution was to tighten it up with an allen key and hey presto all the problems have disappeared. So it was the framing control which was the problem and that is now solved.

Good job, John, glad it's running well!!
