The 3-fold at the top is probably much too thick for
even traction. What I've had success with, on a
LJ-III, is to first print the board on normal paper,
cut a piece of photo paper to cover it with a good
margin and stick it on with white labels, then print
it again, taking care not to print on the label. The
white labels are more heat resistant than scoth tape.
Unless you're very careful when applying it, scotch
tape may come loose or melt somewhere in the path and
pretty much gum up the works. Spent a not-very-fun
Saturday afternoon finding this out.

As my heater/roller combo requires a rather long
"tongue" I've taken to cut a strip the width of the
paper and long enough to print the board. This seems
to make the printing more even, the drum and/or fuser
don't seem to take well to uneven thickness. Makes
sense, as envelopes and other narrow stock are to be
centered in the manual feeder.
