Overlapping frame in Medium format

[scorpion7]

Why does this overlapping happen in my medium format camera? I have Kowa Six camera. Please check the samples to see what I mean. How can I fix this problem? The thing is that this overlapping happened in different sizes but some of them don't have such an issue!

Is it a Kowa six without the removable backs , or the Super 66 model ? Peter

The Kowa Super 66 is the model that has the removable backs.

This is an issue with the film-transport mechanism in your camera or film back.Either or both must be CLAed. You need to find a camera technishn.

Hello,
Does the counter work ?
When the film advances, a roll (n°1 on the pic) rotates at the bottom of the back.
If it doesn't rotate, some functions are defective : counter, film transport.
If you press the push buttons (2 and 3 on pic) and turn the roller, counter has to work.
Perhaps the roll is jammed...

^ The roller illustrated above has come completely covered in deposits of all 3 backs I have , start there . One of my backs also had
a gear which has another gear pressed onto it and although they're supposed to be locked , it would slip . A squeeze in a vice fixed it.
it's got quite the convoluted gear train inside the back . Peter

Curious if Scorpion7 has had any luck with this Kowa Super 66 back ? Peter
