Step 4 Position Scanner
a) Position the scanner in a place devoid of sunlight, bright lights, or laser light from
other sources.
b) Avoid excessive tilt, skew, or pitch. Maximum tilt is determined by label charac-
teristics and the number of scans required. Maximum skew is ±40°; maximum
pitch is ±50°.

c) Pitch label slightly to avoid specular reflection, the return of direct, non-dif-
fused light. For the MS-810 raster scanner, specular reflection is avoided by
pitching labels at least 5° plus or minus from a line perpendicular to the mir-
ror.

Note: Another way to avoid specular reflection is to skew the scanner slightly in
relation to the label.
1. Maximum tilt is determined by label characteristics and number of scans required.
2. The specular reflection zone is a narrow zone straight out from the scanner in which direct
reflected light from a label can distort the scanner’s ability to distinguish bars from spaces.
