Mamiya 645 1000s issue with missing frames

I can't recall whether the 1000s has a multi-exposure capability, but if it does, it might be either set to "on" or engaging and dis-engaging on its own.

The counter doesn't always reset properly which I did notice recently so I had been doing it manually like you mentioned before. This obviously makes it sound like a cut and dried case of counter issue so I'd not mentioned it yet because my instinct had been that it was something else but it is sounding fairly likely to be the culprit, I have to admit. Can't say I noticed an abnormally short winding time but I haven't used this camera particularly frequently so it is something I could have missed.

I will try again and pay extra attention to the counter when loading and see if I run into the problem again.

Just for the sake of my understanding, if I were to make sure that the counter has fully reset and that the film is loaded correctly and yet I still had the issue with missing shots, would that rule out it being an issue with the counter? Is it possible that there could be an issue where the counter is displaying all the correct numbers but not working properly?

Thanks.

I think the sticky counter is the culprit and it's hard to comment on a hypothetical situation. But sticky lubricants in some place could mean trouble ahead.
