Scanning
Decoded scanners must be configured by scanning special configuration bar codes. In these
cases, the scanner manufacturer provides programming manuals for configuration purposes.
The 8515 supports a variety of one dimensional (1D) scanners and two dimensional (2D)
laser and imager scanners.

Scanning Techniques
Note:
•
Hold the scanner at an angle. Do not hold it perpendicular to the bar code.
•
Do not hold the scanner directly over the bar code. In this position, light can reflect back
into the scanner's exit window and prevent a successful decode.
•
Scan the entire bar code. If you are using a 1D or 2D scanner, make certain that the scan
beam crosses every bar and space on the bar code, including the margins on either end
of the symbol.
•
If you are using a 2D imaging scanner, make certain the red, oval-shaped framing mark
is centered within the bar code you want to scan.
•
When using imaging scanners, do not move the scanner while decoding the bar code.
Movement blurs the image.
•
Hold the scanner farther away for larger bar codes.
•
Hold the scanner closer for bar codes with bars that are close together.
