Kiev 4a, problem with advancing film

[Berk Sirman]

I ran into another problem with my Kiev 4a after reassembling it.

While advancing film the sprocket sometimes slips the sprocket holes on film, as a result the film does not advance. The take up spool, pressure plate, film plane casting are all in place as well as the sprocket wheel. Nothing seems to be misplaced as far as I can see. I looked for a way to adjust the action of the roller wheel on camera back so that it would push the film against the sprocket but I cannot find a way to adjust it.

Any ideas how I can solve this?

Thanks, Berk

Didn't you forget to tighten the screw when putting the back film casting back on? there's the small hole on the bottom of the camera (with the back off) where you can access the large-headed screw that keeps the roller with the sprocket wheel in place; if that's lose, things go wrong.
Just an idea.

FIXED.

Turns out the rewind button on the bottom plate was a bit too high and was pushing the rewind button in camera halfway all the time. That is why the sprocket was slipping. I took off a spacer and set the button's action and now it is good. Simpler solution than I thought.
