This is most important while loading or unloading film on a platter. The end of the film should no longer be held by suction cup or other device, but should be tucked under the print at a point where the non-skid pad will hold it firmly in place.
Most normal heights work fine with no adjustment, but take a look.
When loading a print onto a platter using the disc, adjust the MUT roller for proper height. Move the make-up table as close to the platter as possible, with the MUT roller about six inches away from the platter. Using these guidelines, problems with platter operation should be minimal .
