OPERATION
7. Identify your Tab Type using the chart below. Then proceed to the appropriate step.
TAB TYPE DESCRIPTION PROCEED TO
Opaque Stock that has a white space (gap)
between each tab/stamp.
Step 8
Clear Stock that has a black space (gap)
between each tab.
Step 9
See “ Appendix C ” for additional help.
8. Opaque Procedure (For tab/stamp stock with white space between each tab/stamp.)
If your tab type is “Clear”, proceed to the Step 9.
Begin by finding the Gap V or voltage reading from the space between the stamps/tabs.
While carefully monitoring the value
displayed to the right of “V=” (live
voltage reading), slowly move the
tab/stamp web through the sensor until
you obtain the lowest voltage reading,
then press the Gap V key (1).
Note: Manually remove any tabs/stamps
that peel off during this process.
Continue slowly moving the tab/stamp
web through the sensor until you obtain
the highest reading, then press the Tab
V key (2).
Note: Manually remove any tabs/stamps
that peel off during this process.
Tip: In order for the tabber to distinguish between the Stamp/Tab and Backing, the
voltage 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 ”.
Once the V-Tab adjustment for “Opaque Tab Type” is complete; proceed to Step 10.
