OPERATION
7. The next screen allows you to set the
V-Tab values for the head or heads
you will be using.
In this case we will be using Head 1,
so select V Tab 1.
8. Lift the Pressure Roller Release Latch so that the stamp web can slide easily through the
Sensor.
9. Begin by finding the Gap V or
voltage reading from the space
between the tabs.
IMPORTANT! The reading you are
looking for will depend on the type of
tab stock you are using. Please use
the appropriate procedure, shown
below, for your type of tab stock.
Tabs stock with black space (line) between each tab: Move the tab web through the
sensor until you obtain the highest voltage reading, then press the Gap V key (1).
Tab stock with white space between each tab: Move the tab web through the sensor
until you obtain the lowest voltage reading, then press the Gap V key (1).
Note: Manually remove any tabs that peel off during this process.
10. Now set the Tab V or voltage reading of the tab/tab area.
The reading you are looking for will depend on the type of tab stock you are using.
Please use the appropriate procedure, shown below, for your type of tab stock.
Tabs stock with black space (line) between each tab: Move the tab web through the
sensor until you obtain the lowest voltage reading, then press the Tab V key (2).
Tab stock with white space between each tab: Move the tab web through the sensor
until you obtain the lowest voltage reading, then press the Tab V key (2).
Note: Manually remove any tabs that peel off during this process.
Tip: In order for the tabber to distinguish between the Tab and Backing, the voltage
difference between the Gap V and Tab V must be 0.80 volts or greater. If the difference
is lower, check/clean the sensor and then repeat the V-Tab adjustment. If the value is
still less than 0.80 volts difference then you may need to use another tab stock that has a
larger density difference.
To check the function of the tab sensor, see “
Tab Sensor Test ”.
11. When you are finished, press the BACK key (3) twice.
12. Close and lock the Exit Roller Assembly.
13. Lower the Pressure Roller Release Latch.
