O.K. Let's break it down: during exposition your frame is moving vertically. It might be wrongly formed loops (too small or too big), a pressure plate issue = your frame slips when it's supposed to be rock steady) or a fault in the mechanism (synchronism/timing) meaning the shutter is open when the pulldown claw is advancing the frame. Any chance to upload video footage of your K-3 working (open, preferably with scrap film running to see and hear what's going on). My bet is timing issue (needs to be fixed in the front assembly - I can help) since it's a long vertical streak. Also: check the sprocket holes of your processed footage. If there is any damage, the pattern can tell us more about what's wrong.
As soon as I get some film to run through the camera I will record it with the camera opened and upload it on my channel. So by the pressure plate being rocksteady, it should still allow for the film to mover vertically into the take up reel but not allow for it to move vertically by very lightly pulling it with the hand. right? thanks for the help.
Does your K3 have loop formers?
Hi, no I got those removed, does it seem to you like the film is being scratched or maybe a registering issue?
