OPERATING THE TABBER
3. Turn the Tab Sensitivity Adjustment knob fully counter-clockwise. Then turn it
clockwise until the Red LED above the adjusting knob lights. Make a note of the
number that the indicator, on the knob, is pointing at.
4. Turn the Tab Drive Pressure Knob OFF and roll the tabs backwards until the Red
LED goes OFF. Turn the Tab Sensitivity Knob clockwise until the Red LED
lights again. Make a note of the number that the indicator, on the knob, is
pointing at.
NOTE: If during this step the Tab Sensitivity Knob is maxed-out (fully
clockwise), but the LED still does not light; then proceed as if the second number
is 12. If at any time during the tabbing process double tabbing occurs, advance
the setting one more position clockwise.
5. Set the Tab Sensitivity Knobs indicator halfway between the two points measured
in the two previous steps.
Example: If the LED illuminates at position 4 with the tab under the sensor and at
position 10 with the backing or white line under the sensor. The difference
between the two positions is six clicks (10 - 4 = 6).
Divide this number in half (6 ÷ 2 = 3).
In this case, you turn the Tab Sensitivity Knob counter-clockwise 3 clicks, to
position 7, which is halfway between 3 and 10.
6. Turn the Tab Pressure Roller ON and use the Tab Advance Knob to advance the
tab until it starts to peel away from the backing paper.
7. Reinstall the Exit Roller.
Metering Bracket/Separator Adjustment
This procedure is used to insure that only one piece of media is fed at a time.
1. Loosen the two thumbscrews that attach the Metering Bracket to its mounting bar.
2. Raise the Metering Bracket and place a piece of media under the separator
fingers, then lower the Metering Bracket until it contacts the media. Make sure
that material is between all the fingers and rollers.
3. Tighten the two thumbscrews.
4. Remove the media and make sure the bar is level and that the separator fingers are
not rubbing against the feed rollers.
