RE: MZ-S Data imprinting
That's what I said all along. The other way is nearly impossible unless the rewind is really slow since I don't know a single camera that counts sprocket holes on rewind and could snap shot some data while the film is streaming by in hardly over 10 seconds or so. Kent Gittings -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Bill Owens Sent: Friday, December 21, 2001 9:25 PM To: [EMAIL PROTECTED] Subject: MZ-S Data imprinting There was a thread recently about MZ-S data imprinting and whether it was done at time of exposure or during rewind. I can now answer the question. At work tonight, I put the MZ-S in our dark box, opened the back and removed about half a roll. Stuck it in the film processor and when it exited, the exposure data was where it was supposed to be. Therefore, the MZ-S imprints the exposure data at the time of exposure.

Second time lucky? The gold pins are the electronic contacts between the data back and the body. The imprinting device for placing date information on the film is located behind the pressure plate and inside the exposed film area. The IR sprocket hole sensor assembly is located at the top right (when looking at the body from the rear, prism pointing up) at the elevation of the sprocket holes. The imprinting device for film exposure data is located at the bottom right (when looking at the open rear door from the rear of the camera, prism pointing up) of the pressure plate on the rear door. This places it adjacent to the film supply spool when the back is closed. Therefore the data must be printed on rewind otherwise the camera would need to back up the film then advance to write the data. Unless of course the camera pre-advanced the film and the exposure sequence was in effect reversed. So Pål's explanation seems to correlate with the physical lay-out of the camera and Bill's results are a total mystery?

This is NOT the dtataimprinting emmitter but the sprocket hole sensor. The data is imprinted on the top of the film. Since the the image is formed upside down in the camera, the emmitter must be located at the bottom end of the film chamber, something it is. The emmitter position is stated in MZ-S litterature and in the patents. The emitter is at the lower right corner of the pressure plate when the back is opened.

RE: MZ-S Data imprinting
Paul Wilkinson explained he re-winded the film before removing the film out of the camera, so it could be very well Pål is correct. I assumed printing was done after rewinding the full film, but it would make more sense to do it after the rewind of a partially exposed film and not wait. Although personally I would have designed it during wind immediately after the shot, it takes only one shot to remember in that case. Perhaps they didn't want to slow the camera down to this and have a (further) negative impact on the frames per second number, which seems important to some people. I think one of the MZ-S owners need to do this: remove the film in a dark bag at frame 35, rewind it outside the camera manually into the canister before processing it. And then let us know what happened. Frits Wüthrich - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.

Re: MZ-S Data imprinting
> This make no sense. It is imprinting on rewind that make mid roll change and roll number count totally hassle free. Think of what happens: every time you open the back door of your camera the memory is getting cleared. This mean that you can reload a film 36 times if you like and the camera will only imprint those images you shot after you relaoded the film cause thats all thats in the memory. You need memory anyway if you don't use a row of emmiters that fires simultaneously during exposure (something thats impossible anyway cause theres no way you could have made sure that the data is imprinted between the sprocket holes). After all, you need a sprocket hole sensor separated from the data emmiter something tha means that there will be a time delay between exposure, sprocket hole sensoring and data imprinting. Memory is needed anyway. When using mid roll change, you have to dial in the frame number before loading the film. It evidently counts sprocket holes. If you tell the camera to start at frame 4, and you have already exposed through frame 6, you will have double exposures on frames 4-6.

I just checked my MZ-S and the data imprinting emitter is not where the film comes out of the cassette, it's on the other side right next to the take-up spool. (The time/date imprinting emitters are on the cassette side, though, but mounted behing the film pressure plate.)

I don't know what you did but what you describe is impossible. 1. The dataemitter led is a point source. Theres no row of emitters. Hence, it cannot print during exposure. Only during wind or rewind while the film is traveling. The dataemitter is on the right side of the pressure plate on the back (right side when the back is opened - left side of the film chamber) 2. The data cannot be imprinted during wind due to the fact that the dataimprinting emitter is placed on the left side of the shutter. This means that the emmitter is placed next to the next shot on the film not the one you are shooting. Ie. if dataimprinting was done upon winding data will be off with one frame on all frames; data for frame 12 would be imprinted on frame 13. The only way to make dataimprinting work upon wind and shooting is for the camera to have telephatic powers so that it knows the exposure before you make it! Imprinting can only happen on rewind. To put it clear: the film moves from left to right. The dataemmitter is to the left. This means that the film is transported past the emitter BEFORE the image is taken. Hence its impossible to imprint data during exposure or wind. 3. The dataimprinting during rewind is also proven on those cameras that had the over lapping frame syndrome. The overlapping frames did not have overlapping data imprinted something that would have happened if the imprinting followed the wind of the camera. The data was imprinted as it would be if the camera frames were correctly spaced. This could not have happened if data were imprinted on wind. 4. The Pentax MZ-S patens clearly state how the data is imprinted on rewind. That it use a sprocket hole counter and memory of exposure data deleted upon rewind of the film. 5. Theres no way possible to make dataimprinting between the sprocket holes upon exposure/wind without variable speed winding and/or uneven spacing between frames or very sophisticated sensor and emmitter software making sure you don't pint IN the holes not between them.

I have never seen a MZ-S real life, but it would make sense to me the writing is done during the film transport immediately after taking the exposure. Waiting to print during rewind would require the storage of the data in memory for all shots, and think about the additional hassle for mid roll changes. Printing during transport allows for a single row of LED's that need to be fired in a sequential way. A single print would require a LED matrix which would be a more costly approach I guess.

Re: MZ-S Data imprinting
Cool test Bill... and practical! Though I likely will never own one, it seems that imprinting at rewind would be problemmatic and needlessly complicated.

This is why the MZ-S has the "dial-in the first frame number" feature. If it didn't and you used the conventional lens-cap-on, 1/6000th at f/22 technique, the original imprinting would be overwritten with the above data.

Re: MZ-S Data imprinting (WAS: RE: MZ-S Film-rewind Problem) - SOLVED
paul, Thanks for the extensive test. From your results, I'm guessing that Mid-roll change will work with data imprinting because the body would know how many frames it skipped. If you used the old method -fire until the right frame (kept dark of course), would probably double imprint the first portion of the roll. I, too, love the MZ-S. It is a joy to use!

A bit late, the Contax RTSIII (over 10yrs old, integrated vacuum/date back) prints its date info (a bit early for exposure info imprinting) on the strip between the frames of adjacent exposure, still a problem with mounted slides though.

What I meant was: Is the data imprinting done as one large array of pixel, or like an old-style dot matrix printer, where there is only a column of dots that moves across and forms the letters as it is moving? In this last instance, the 'single column' of dots would be fixed and the film would be moving in front of the column. Michel - This message is from the Pentax-Discuss Mail List.

AHA! That would be different than the way the MZ-S reportedly does it (imprinting only 'B'). Does the 645N imprint WHILE the film is advancing to the next frame, one row/column of dots at a time, or is it done all at once?
