vertical support plate of the printer to the inboard edge of the stock at both the
feed roller and the unwind. This measure should be the same distance at both
locations. To move the stock inboard at the feed roller, away from the operator,
loosen the outboard screw slightly. This can be done while running the printer.
To move the stock outboard at the feed roller, toward the operator, loosen the
inboard screw slightly.
Stock Out
A micro switch located on the back of the unwind will detect when the stock core is
lifted when the stock is consumed and stop the printer.
Hole / Slot Index Registration
The hole / slot registration is via an optical sensor used in conjunction with an LED
light bar located in the stock funnel which allows the printer to register to pre-
punched possible preprinted stock.
Reflective Index Registration
The same optical sensor used for hole / slot registration, allows the printer to register
to preprinted stock by detecting a black mark when the LED light bar is turned off
via the format.

Ink Out

Optical sensors located on each print station's ink unwind arbor allow the printer to
monitor the availability of ink.
Roller Drop
An optical sensor on back of print station number two allows the printer to control
and register the platen roller position to perform ink save.
Feed Open
A micro switch on the back of the feed module will detect the position of the feed
module pressure knob and only allow the printer to operate with the feed pressure
knob closed.
Jam
An optical sensor located in the stacker will detect each cut label as it leaves the
cutter. If a cut fails to occur or a label remains in the sensor sight path, the machine
will stop.
Full Stacker
A micro switch in the stacker rails allows the printer to detect a full load of labels in
the stacker. The stack full condition will stop the machine when the stacker is full.
