I have a problem with my Konica Autoreflex T3 (but I know I had it also earlier with a Canon FTb).
Sometimes when winding, the film slips. I then can press the shutter and wind again to get the film further.
Is there a common solution to this? I looked into the camera and the film reel looks fine. I dont know why it slips off the transport wheel. |

This may be something that I've encountered before - happened to be on an Autoreflex T, but I think many cameras are similar. The plastic film sprocket is driven by the head of a small screw in the side of the metal inner shaft that runs down the center of the sprocket. This screw head engages a slot in the inner wall of the plastic sprocket, and is disengaged when you push in the rewind button from the bottom.
The plastic wears out over time, and then the shaft slips. If it's not too bad, you can insert a second screw opposite the existing one (there are 2 slots in the plastic part) to double the strength of the engagement and make sure that, if one of the 2 slots is still in pretty good shape, you're always engaging the good one.
Open the back of the camera, advance the sprocket until you see the small vertical slot just above the upper sprocket teeth... now press in the rewind button, and the screw will come up into view. Or, you will see an empty hole where a screw could go. If you see the screw head, advance another 180 degrees and you'll see the empty hole.
Either find a short screw that fits in this hole, with a head that will fit in the slot so that the inner shaft moves freely up and down as it should ... or, remove the existing screw and find a longer one that will go all the way through the shaft and engage the plastic tube at both sides.
If this is the cause of your problem, then this fix will at least buy you some more years of use. Once this has worn out both sides of the sprocket, the camera is toast.
If the above is not the cause of your problem, please disregard this message
