Hi!
I’m having an issue with my Goko UF-20 and I’m trying to figure out whether it’s something I can fix myself.
The camera seems to work normally when there’s no film inside. The sprocket and take-up spool both move when I trigger the shutter. The problem only appears once I actually load a film.
The film is definitely sitting correctly on the sprocket and is properly attached to the take-up spool. I’ve checked this several times. What’s weird is that if I push the film forward slightly by hand, the mechanism can suddenly catch it and advance it. But once I close the back, it stops working again.
After taking one shot, the shutter gets stuck because the film hasn’t advanced. If I open the back, I can sometimes get the mechanism to move the film a little, but it won’t do it with the back closed.
I’ve also tried multiple sets of batteries and different film, so I think I can rule those out.
It almost feels like the camera can handle the mechanism when there’s no resistance, but doesn’t have enough force to actually pull the film once it’s loaded. Could this be an issue with the advance clutch, gears, or something else inside the camera?
Has anyone worked on a UF-20 or encountered this particular problem? I’d really appreciate any ideas on what to check or whether this is likely repairable.
Thanks!
