Description of the Working Steps for the Gap Sensor (Transparent Sensor):
A) Start the printer in the Service Mode, compare section 7.2.3 (necessary for steps in section D).
B) Select the Paper Type
Label with Gap
Please go to [Paper Type ] in the printers menu structure:
Paper Menu\Paper Type\ select Label (with Gap)
(use PREV or NEXT key, then ENTER)
C) Set the sensor (T) to the accurate position (upper and lower sensor)
See section 7.2.1 Checking and Adjusting the Position of the Sensors
D) Sensor Current (CV value) adjusting
Please go to Sensor Test and select the subpoint Gap:
Engine\Sensor Test\ select Gap
The currently measured sensor level (contrast) is displayed.
Press the ENTER key again, after this 2 values are displayed:
Left VV = curr.measured sensor value(level) Right CV = reference value for sensor current.
CV is modifiable (and has an effect on the VV value).
Gap
Use the NEXT and PREV keys to set the CV value. Approx. CV value:
Put the liner (not the label) of your material into the sensor.
Increase CV (current) until the sensor measured value (VV level) of the
liner is under 10 %.
After that increase CV (sensor current) by another 3 %.
Load label (with liner) into the sensor.
The measured sensor level (VV Pegel) of label should count
as possible more than 40 %.

If the sensor measured value (VV level) of label is too low,
the CV value should be decreased.
Higher label VV values than 40 % are more advantageous so long as
there is no rising above 10 % of the liner VV level.
Measure both sensor levels once again for Liner and Label.
(You need the two level values of your material for the following switching threshold adjustment)
Save the new current value (CV) using the ENTER key.
25 %
+ 3 %
E) Sensor Switching Threshold adjusting
Please go to [Sync.Sens.Level ] in the printers menu structure:
Engine\Sync.Menu\Sync.Sens.Level
At the right the switching threshold value is displayed.
Use the NEXT and PREV keys to set the
switching threshold of the sensor to the
middle between the liner level and the
label level:
Save the new switching threshold
(ENTER key).
Hint:
The displayed
level value is
directly valid for
printers with a
threshold setting
range from 0 to
100%.
If your printer is
provided with a
threshold setting
range from 0 to
200%, the setting
value has to be
doubled.
