Mamiya 645 AFD Troubleshooting: problems using film back

[Nevin117]

Hi everyone, just wondering if anyone has faced these same issues.
I have two digital backs that work completely fine with the camera. Unfortunately I haven't had very much luck with the film back.

1. When the film back is attached to the camera I cannot remove the dark slide.
2. I partially released the dark slide using the little button at the bottom of the film back. But unfortunately thereafter the dark slide cannot be reinserted for the film back to be released.
3. The camera isn't winding at all or on to the first frame after being loaded. The display on the back shows correct ISO and 120 but (- -) where the frame count should be.

I've tried cleaning the contacts both inside and outside the film bac,k as well as reloading the film just in case that was the problem.
If anyone has any tips or hints they would be much appreciated! Thanks in advance!

Welcome to Photrio! Sorry to hear about your issues with the 645AFD. I've added a few words to your thread title so hopefully someone will recognize the issue and come in and share some advice.

Not specifically a response about the Mamiy AFD" It sounds as if some mechanical interlock, triggered by something in the body, is not being triggered properly for the film back to recognized that it is mounted...so the interlock is preventing removal of the darkslide, to protect the film.
