Laser Scanning Instructions
Using a laser scanner is basically as simple and intuitive as "point and shoot" at a distance of 0-24", depending
on the density of the bar code.
Basically, the laser scanner's beams must cross every bar and space on the bar code, without touching any
other bar codes, as shown in the first example below. You'll need to hold the scanner further away to produce
a wider beam for large bar codes, and closer for bar codes with bars very close together.
Even though momentary exposure to a laser's low-power, visible-light is not known to be harmful,
you should
not aim the beam into anyone's eyes
.
The important thing to remember about using a laser with the RF Laser Reader Setup Menu is that you need to
make sure the scanner's beam covers only one bar code at a time. The laser scanner's beam is wide enough,
and the configuration bar codes close together enough that you will need to use your fingers or a few pieces of
note paper to "block off" bar codes adjacent to whatever configuration bar code you need to read.
For example, to
read this "5" bar
code on the Setup
Menu, you would
need to cover any
adjacent bar codes
with paper or a
finger first, as shown.
