Do not lose the spring! It holds the platen tight against
the right hand end of the truck, and is essential for
good print registration.

Truck interlock (arrowed)

If there are no cards present in the hopper, and a hot
load is attempted while the truck is elsewhere, the
cavity under the hopper is exposed and potentially

dangerous. Active when the hopper cover is open, the
truck interlock prevents the truck from driving to its
home position.

Truck home sensor

Determines the truck’s end stop position. Activated by
a vertical flag on the left edge of the truck, photo
above.

Card presence sensor

Located behind the mag encoder.
