2.7 Checking The Scanner
If your 7535 is equipped with an internal scanner, it will successfully
decode most 1D bar codes as delivered. Press the SCAN button or
the pistol trigger, and check for a valid decode on any UPC bar code.
2.7.1 Scanning Techniques
Note: The scanning techniques described here apply to internal
and external scanners.
• 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.
• Hold the scanner farther away for larger bar codes.
