Pentax 6x7 MLU winder locked extended

mweintraub · May 8, 2017

I just shot the last frame on a roll of 220 film and the winder stuck in, what seems to be, the fully extended position (maybe there's a mm or more push). The shutter won't trip and the secret button didn't do anything. I will try a new battery when I get home, but does anyone have any other idea? Thanks.

Did the 120/220 switch get moved by any chance? This could block everything.
What do you mean by "the secret button"?

The film advance mechanism on the P67 has always been a "week link." When they reengineered the P67II they also reengineered the film advance but it can also give the same problem. I bought my P67II new in 2000 and had the film advance repaired by Pentax repair in Golden Colorado around 2005. Since then no issues but I have taken care since to advance the film more slowly and softly than before. The only issues since is dirty contacts ("Peer" or something like that appears on the screen) but that is readily cured with an eraser.

It already got improved in the 6x7 MLU, i don't know if it was made even better in the 67.
Anyway, the manual insists on not messing with the 120/220 button on the side after the door is closed.

Did you take the film out?

OK everyone, thanks for the replies! I'll have to say there is a happy ending to this. Yes, the film was removed after and safe when this happened. It looks like I didn't push the winder all the way to where it would ratchet back. My fault. I'll be more careful next time.

Strange, that would have been the first thing to try.
Anyway, I'm happy for you, I also love my P6x7 and the thought of having to part with it would be unbearable.

I did push it a little bit, but didn't want to push it too much that something would break. The 6x7 is not a body you force anything with, especially the winding system from what I've heard.

You're right, never force anything.
But maybe sometimes, a little bit of force is alright.

mweintraub · May 10, 2017

I thought I was giving enough force before as I was seeing the shutter move... I guess not.

Thanks -- I did exactly the same thing. Even though I am an experienced film shooter
