LABEL SENSOR ADJUSTMENT
THE L-350 HAS BEEN FACTORY CALIBRATED TO DETECT THE PRESENCE AND
ABSENCE OF LABELS UNDER MOST CONDITIONS. HOWEVER, WITH THE
VARIATION OF BOTH LABEL AND BACKING PAPER DENSITY, IT MAY BECOME
NECESSARY TO FINE-ADJUST THE SYSTEM.
1. Locate the LABEL SENSOR
ADJUSTMENT knob [Figure
9A] and red light emitting diode
[Figure 9B] on the non-operator
side cover. Turn the switch fully
COUNTER-CLOCKWISE to
position 1.
2. Thread labels/tabs/stamps into
the labeler following the
diagram [Figure 5 or Figure 8].
3. Turn the LABEL ADVANCE
[Figure 3D] knob until the first
label (or tab) just starts to peel
off the backing paper.
4. Turn the LABEL SENSOR
ADJUSTMENT [Figure 9A]
knob CLOCKWISE until the red
L.E.D. is illuminated.
5. Release the label pressure
roller (turn it off) and pull the
label material approximately
two inches out of the machine.
This ensures the backing paper
is the only part, which is seen
by the label sensor. The red
L.E.D. will not come on at this
time.
6. Turn the LABEL SENSOR ADJUSTMENT knob CLOCKWISE and count the number
of clicks the switch makes until the red L.E.D. comes on.
7. Now turn the switch COUNTERCLOCKWISE half the number of clicks that you
counted.
EXAMPLE: the light comes on at the sixth click. Now remove the tab from in front of
the sensor and turn the switch six clicks CLOCKWISE. The light comes on again. Now
turn the switch three positions back or COUNTERCLOCKWISE.
THE SYSTEM IS NOW CALIBRATED TO THIS TYPE LABEL.
THIS STEP CONCLUDES THE INITIAL SETUP AND ADJUSTMENT PROCEDURES.
