Cleaning cassette
TOP: As the drive motor begins to turn, the drag
caused by stickiness of the cleaning tape on the supply
roll creates a clockwise turning force, bringing the
cleaning tape into contact with the cleaning roller. The
motor continues to rotate for a second or two, pulling
fresh tape out of the supply roll. This in turn rotates
the cleaning roller, at the same time removing debris
from its surface.

molding
The base molding is secured to the aluminum
transport by buttonhead screws through the six stand-
off springs seen here. The molding is NOT screwed
hard down. It floats on the springs, and is adjusted up
and down by the buttonheads to set the “card gate”
height relative to the platen at just over the thickness
of a single card. If the base molding is set too high, the
truck will attempt to make off with more than one
card: if too low, it will leave the hopper area without a
card.
