OPERATION
9. Clear Procedure (For tab stock with black space/line between each tab.)
If your tab type is “Opaque”, see Step 8.
Begin by finding the Gap V or voltage
reading from the space between the 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 highest voltage reading,
then press the Gap V key (1).
Note: Manually remove any tabs that
peel off during this process.
Continue slowly moving 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 then 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 ”.
10. When you are finished, press the BACK key (3) twice.
11. Close and lock the Exit Roller Assembly.
12. Lower the Pressure Roller Release Latch.
13. Test the T-650 for proper operation. If you experience tab advancement or positioning
problems, verify proper threading, transport setup, media length, tab type and tab pitch
settings.
