Laser And Linear Imager CCD 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. Our Linear
Imager CCD scanners are also "point-and-shoot" and offer “laser-like” scan
distances of 0 – 11 inches from the bar code. The LI101-RF Linear Imager
CCD and the 1-way LZ200 RF Laser both beep only at the Base Station, so if
the Base Station beeps, it got the data. The LZ202 RF 2-way Laser and the
LI102-RF 2-Way Linear Imager CCD both beep at the scanner as well as
the base.
Basically, the Linear Imager CCD and 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. For both the laser scanners and the Linear Imager
CCD's, 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 Wireless 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 the supplied Laser Setup Assist window, 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.
