Scanning Items: Model 2200VS
Item bar codes are scanned by either...
• sliding or pushing items through the scan volume in a right-to-left
or left-to-right motion (see
Figure 1
a). This is known as “Sweep”
scanning, and is the best choice for high throughput super- and
hypermarket installations where it is necessary to minimize the need
to grip or lift items.
• moving the bar code directly toward the scan window to be read (see
Figure 1
b). This “Presentation” technique is most often used in low
throughput variety, convenience market and pharmacy applications
where usable countertop space is at a premium and “Sweep” scan-
ning is not possible.
