Hi I have had the same problem with my S800 and my NIZO BAUER. Friends have pronblemas with other cameras. Is it a problem of film cartridges 100d? Hitting the cartridge several times before shooting. If you get stuck and re-tap. Not an uncommon problem, there is a fix for it thanks to Martin B: _http://www.cinematography.com/index.php?showtopic=52896_ (http://www.cinematography.com/index.php?showtopic=52896) "Regarding the other issue, of the EK100D film being thicker and running rougher etc. This has also been an issue many times with the previous EK64T as well. A similar situation can occur with FOMAPAN R-100, which normally is not available in Super 8mm cartridges but can be custom loaded that way privately. As with any Super 8mm film cartridge film sticking or jumpiness incamera problem, a nice wipe of the film gate with a clean cotton flannel cloth moistened with pure Silicone will solve that. Should a cartridge give further problems, pull the film out of the cartridge gate so you can wipe the pressure plate with Silicone as well. That has cured 99% of any problem I've ever had with cartridges being problematic that way. Super 8mm film cartridges will jam for a small variety of reasons: [1]. High humidity present in environment upon opening of foil seal pack, causing film emulsion to swell like a sponge...that part that's exposed in the cartridge gate. This will usually cause a film to jam right at the beginning. SOLUTION: pull the film downward and rotate the takeup core clockwise to take up the slack. If very humid, make sure to wipe film gate with Silicone....if a deep film chamber such as a rear loading camera (which the NIZO is), you can just GENEROUSLY wipe the exposed film surface with Silicone and it will wipe the camera gate when you reinsert it. [2]. Film jamming from using the Film Rewind, Double Exposure, or Lap Dissolve function on a camera. What happens is the film will jam, either because the rewind function was begung too early in the cartridge (wait until at least 5 feet of film has been run) or too late in the cartridge (don't inititate a film rewind within the last 5 to 10 feet of a cartridge's remaining film length). SOLUTION: Take up any film slack by rotating the film takeup core clockwise, if no slack....then depress the Pressure Plate in the cartridge by using a small screwdriver or tweezers to either side of the film...and while holding it in, pull the film downward. Do this for a few inches of film, sometimes it has to be done for as much as a foot of film....then keep taking up the slack by rotating the film takeup core clockwise. NOTE: Should the film NOT pull down due to a severe jam....do NOT force it then. The film could just break. Notify the lab of a film jam in this situation when sending it in for processing. [3]. Film jam caused a film pull-down to takup core rotation problem.....or by using high running speeds in a given camera ( Slow Motion ), in which the film takeup core isn't rotating fast enough to keep up with the film fed to it from the cartridge gate, so it overslacks into the takeup chamber side of the cartridge. This either manifests itself via a full jam, or if shot at normal running speeds of 18fps or 24fps, can just cause the film to jitter while it's running. SOLUTION: remove cartridge from the camera and wind up the excessive slack in the cartridge by rotating the film takeup core clockwise until the film is taunt. Do NOT force the film too tightly. If the problem persists on a given camera, then use the film in another camera instead and/or avoid using the Slow Motion feature on that given camera causing the problem (IF the problem only happens in the Slow Motion mode setting). [4]. Film manufacturing problem regarding sprocket holes (perforations) or a faulty cartridge where film is not unspooling from the supply side smoothly due to a warped or jammed Slip Disc (thin plastic disc the film sits on and rotates as it feeds) or a jammed or popped-off or otherwise damaged film feed roller which is just above the film gate where the film turns over on so it's emulsion side out as it runs thru the film gate. Any cartridge related problem requires opening the cartridge to assess the problem, resetting the film in the fixed cartridge or another one, and then sealing up the cartridge. ADDENUM: There's another way to fix jammed Super 8m Cartridges, but it is involved and requires opening up the cartridge and resetting the film correctly so it will run. If the jam occurred early enough before main filming, it's best to just rewind the entire film load and reload it into a good working cartridge. I know what you're thinking, where does one get this done. PPS does this type of service here....but if you do your own film processing, you can learn how to work with the cartridges to use them. It does require making up a small jig to wind the film up for the Supply Side of the Super 8mm Cartridge so that it will rotate on the stationary hub smoothly.
