Chapter 1 Adjust The Scanning Beam

Peel-Off Media Handling Mode
If your printer is configured for Peel-Off Media Handling mode (use
of optional internal rewinder), you may need to align the beam
further behind the notches (0.20 to 0.30 inches [5.08 mm to
7.62 mm] from the front edge of the tear bar) so that the peeled
label remains on the tear bar and the trailing edge of the last bar
code can still pass completely under the scanning beam. See
Figure 12.
Aligning the scanning beam to any position other than the notches
on the tear bar should only be done if the last printed bar code
image does not clear the beam when the label is at the peel-off
position after printing. In addition, the distance the beam moves
back from the tear bar edge must correspond to a distance from the
leading edge of the label that does not have bar code printing. For
example, aligning the beam 0.20 inches from the front edge of the
tear bar requires that 0.20 inches of the leading edge of the label
must not have bar code images.
