GAP [X.
XV]
INPUT
The
“Se”
Series printers determine the location of the leading
edge of the label by measuring the difference between light
levels when it sees either a label edge or a black
“EYE”
mark.
This adjustment allows you to manually set the threshold
voltage level, between the maximum and minimum light levels.
DIP switch DSW2-2 selects the sensor type. If DSW2-2 is in
the OFF position, the setting will be for a See-Thru (or Gap)
sensor and the LCD will display
“GAP”
on the top line along with
the current setting. If DSW2-2 is in the ON position, the LCD
will display
“EYE”
on the top line with its current setting. If the
value entered for the bottom line setting is
“0.0V”,
then the
printer will automatically calculate the setting when the first
label is fed after the printer is powered on or the head is
closed. There are some instances where the automatically
calculated value must be adjusted to ensure reliable label
feeding, such as when the backing opacity or the
reflectance
of the EYE mark varies significantly within a roll of labels or
between label rolls. In these instances the value should be set
usin
the followin
rocedures.
GAP [
.XXV]
INPUT
GAP - When setting the
“gap”
threshold, the voltage shown on
the top line of the display must be measured with nothing but
the backing in the sensor and then again with a label still
attached to the backing. The formula to be used for setting the
threshold is:
(High Voltage Level + Low Voltage Level) x 0.5 = Start Value
1. Insert a label still attached to the backing into the sensor
and close the Label Hold-Down. Record the voltage shown
on the top line of the LCD panel. This line should have the
message
“GAP”
on the top line (DIP switch DSW2-2 =
OFF). Make sure the label is all the way under the sensor.
2. Strip the label from the backing and insert the backing strip
under the sensor and close the Label Lid. Record the
voltage shown on the top line of the LCD
panel. The voltage
ranges measured should be within the following ranges:
Backing with label = 2.0V to 3.5V
Backing without label = Less than 1.0V
If the measured values are outside this range, you may have
trouble in finding a value that will work properly under all
conditions. If this is
the case, a higher quality label may be
needed to get adequate performance.
