Your new scanner represents the latest technology in
laser scanning. Being a presentation scanner, you
present the label to the scanner. This eliminates the need
of moving the label past the scan window, reducing the
amount of operator activity.
The 7890 Presentation Scanner is a small, compact unit
that weighs less than two pounds. Figure 1-1 shows the
scanner, connecting cables, and power module.
