Folds
Do not fold products where there is freshly
printed ink. Any ink located inside a fold will not
be exposed to IR radiation in the dryer, and will
not cure (Figure 21). That being said, areas that
do not contain ink can be folded.

Height Sensor Adjustment:
Each belt has a height sensor system (Figure 22)
located in front of the heat chamber to detect and
prevent oversized objects from entering the
chamber.
Figure 22: Height Sensor Adjustments
The system consists of a laser emitter on one side
of the belt, and a laser receiver on the other.
When an object blocks the laser beam from
hitting the receiver, a height sensor event is
triggered, stopping the belt. When this occurs, a
notice appears on the main control kiosk (Figure
23), along with a barcode. The belt can be
restarted by pressing the notice on the main
control kiosk, by scanning the barcode on the
notice, or by scanning a “reset height sensor”
barcode printed from the “Settings” Screen
(Figure 24)

The height sensor system may be adjusted to
increase or reduce the allowable object height.
Adjustment is accomplished by loosening the
screws holding the laser emitter and receiver in
their adjustment slots (Figure 22), moving the
components up or down, and retightening the
screws. Adjust the emitter and receiver as
necessary such that the laser beam hits the center
of the receiver, and the yellow light on top of the
