Pentax 67II Weird Winding Situation

[braxus]

So I go out on a morning shoot today and one of the cameras I brought was a Pentax 67II. Haven't had any issues with the camera till today. But I wonder if it was my fault for that? I loaded a roll into it over a week ago, and it was ready to shoot on shot #1. But I had to remove the roll (in a dark bag), so I could use another roll in the camera, and the roll that was in there I put in my other 67 camera to test that camera. My procedure for removing the roll out of the 67II was (after it was in my dark bag), I opened the back, dropped the pin holding the bottom of the film takeup reel, and slid out the roll. I don't think I turned the film in any way while removing it. I closed the back waiting for todays shoot. So today I try to load my first roll into. What happened was the winder lever was moving as it should, but the film reel was not spinning. So I took out the take up spool and looked. I tried winding again. What I noticed was the center of the winding spool section was turning, but the outer ring around the center, would not turn. I could not get the outer take up ring to turn no matter how many times I wound the lever. So I gave up on using the camera today for its shoot. Got it home. I put a slight bit of pressure on the outer ring, and it would not turn. I stopped because I didnt want to strip any gears. Fiddling with it some more, opening the back and closing, etc, and somehow I got the shutter to fire. Before it wouldnt fire during the winding process. So I thought, good, some progress. But then winding there wasnt any tension on the lever and again the shutter would not fire. So played with it some more and eventually the shutter would fire. When the shutter was working again, I noticed the outer wind spool thingy (the slots where the reel sits in its grooves) was turning again, as was the center portion. And I noticed the tension on the wind mechanism was good again. Fired off the shutter some more times after each wind, and now the camera seems good again. Was the camera stuck in a mode during the time I removed the film with opening the back, screwing up the whole shutter process? Im just happy I dont have to send the camera in for service, unless I end up having more wind issues in the future. Anyone knows what was going on with my camera?

Hi, I have had similar problems with my 67ii. Tell me if my descriptions sounds like yours. It seems that sometimes I need to do a "double stroke" to properly cock the shutter. But this ends of skipping a frame of 120 film in the process, and so wastes film. My troubleshooting and understanding of the camera pales in comparison to yours. But a friend who I lent it to initially discovered the problem, which he thought involved the pressure plate at the back of the door that holds the current frame plane. He said that he would change the pressure plate to the 220 setting, and somehow thus avoid this problem. I am confused by how this could have any relationship to the problem of winding the film but not properly cocking the shutter, but he reported that it seemed to solve the problem.
Are we talking about the same problem? Do you have an understanding of what might be going on?

I dont think its the same issue. Someone mentioned the 67 cameras dont really like film being removed mid roll (or in my case, the start of it). They were saying to fire off the entire roll with blank frames and then remove the roll to reuse it. I'll keep an eye on it to see if there really is an issue with my camera, but the 67II is an electronic camera, and maybe it was keeping track of the frames to be shot, even if the roll was removed.

I have no idea. However, could it be battery related? Cold weather, low voltage??? Ghost in electronics. These are beautiful cameras.

I think you're on the right track

Battery is fine. I wish the 67II had a battery check though. The old 67 does.

It seems that the OP sequence left the camera in an unexpected status (shutter cocked, advance locked, back opened, multiexposure not active). When a roll is finished the shutter is not cocked again. Normally you need to reach a expected status to recover functionality.

Wind on issue are documented on the Pentax 67 series, one is jamming, and the other is not winding on. I believe both are due to the ratchet paws, either breaking, or getting stuck open with thick grease.
