[Frameworks] Canon 1014XL-S/ 814XL-S problems with 100D film stock

Thanks, really useful stuff!
How come all the responses to this thread don't stay in the same thread? I've been hunting through my inbox looking for all 100D related emails. I've copied and pasted useful stuff to a word doc... Would be nice if it all stayed in one place though.
All the bestKevin

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:

"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 sla ck....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.
