OPERATION
7. The next screen allows you to select
the Head and corresponding Tab
Sensor that you want to set the V-Tab
values on. In this case we will be using
Head 2, so select V Tab 2 to set the V-
Tab values for Tab Sensor 2.
8. The Tab Sensor 2 Setup screen will
appear.
Lift the Pressure Roller Release Latch
so that the tab 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 ”.
