6.2 Backgauge Control
The backgauge is used to position paper to the desired location when cutting. The backgauge is
operated by the hand crank at the front of the machine. The backgauge position is shown by a
lighted LED display. When the machine is first powered up, the display shows four lines as follows,
indicating the display needs to be reset.
Figure 5 – Display at power up
To reset the display, bring the backgauge to the forward most position. If the backgauge is already at
the forward most position, move the backgauge back by a few turns, then bring it forward again. Now
the display should show the actual position of the backgauge (Figure 6). If the machine is left on all
of the time, this should be done at least once per day. The position of the decimal point indicates
whether the reading is in inches or millimeters. Two digits to the right of decimal indicates inches,
one digit to the right of decimal indicates millimeters. To switch from inches to mm and vice-versa,
press the inch/mm button located next to the display.
