RE: [APML] Bad E6 processing

["Sean Walker" <swalker@SkyandTelescope.com>]

I used to do E-6 and C-41 processing at a quickie photo store in Cambridge.
what would happen is occasionally at the end of the day, someone manually
loads a card with slide film into the processor, and forgets to check if a
card is already in the machine, it usually flashes (but not completely
obliterates) between 4 and 10 frames on the roll that was in the machine.
the reason it doesn't kill it all is because some of the film was already
curled down into the first bath, and some of it was still in the film
canister. the part that was yellowish was just entering the bath. does it
look like a sharp/sudden difference on the end that seems to be unaffected?
that would be the clincher of my theory. mailed in film to Kodak uses the
roller machines.

With what?
Another thing I noticed is that frames 1 and 2 are clear with some
yellowish/orange color covering half the frames
