I have run 2 rolls of 120 film through the back, and when developed, the exposures overlapped about 1/8 to 1/4 inch.

Is there an ajustment to prevent this?

Thanks.

No adjustment that I'm aware of. The problem seems to be caused by wear in the gear train that advances the film.

Just a thought... Is it possible you are using 6x7 insert in a 6X9 film back? How many frames do you get per roll?

I checked the rollback and the opening is about the same as a 2x3 negative in the short dimension, but much larger in the long dimension.

The roll back s clearly labeled 23 120 Rollback

The plate doesn't appear to be removable.

The frame indicator on top indicates 8 frames.

It has a roll of film in it so will shoot the next half and take a good look at it.

Thanks for the help.
