Hi everyone,
So I've recently repaired a GX680III and am using a 120 film back with the system (type I). It's getting to be a weird thing though as I shot a roll of film through it twice but now when I load the film cartridge and it starts to wind on to the beginning of the film, it keeps on winding until the spool is empty and wastes the whole roll. Is there some sort of sensor that needs to be cleaned or should I be looking for a whole new 120 back? Interestingly I have a 220 back which came with the camera initially and this shoots and winds on with 120 film just fine. Any insight into why the film back would wind on would be helpful. Thanks!
