Roller Drop (686) – Not on 686 HT
An optical sensor on back of the printer upright 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 on the stacker rail 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.
Sensor Adjustment
All the micro switches and optical sensors in your 686 / 686 HT printer were
calibrated at the time your printer was manufactured, however from time to time it
may become necessary to readjust
/
recalibrate due to the large variety of stocks and
inks that can be run on the machine.
Stock Out
With a full roll of stock loaded on the stock unwind with the unwind web guides
properly adjusted you should heard the switch click as you raise and lower the roll.
If not - the switch bale is adjusted by carefully bending it as needed.
