SE-923 Scan Engine Integration Guide
3. Position the symbol so that the scan line is as near as possible to perpendicular to the
bars and spaces in the symbol.
4. Avoid specular reflection (glare) off the symbol by tilting the top or bottom of the
symbol away from the engine. The exact angle is not critical, but it must be large
enough so that if a mirror were inserted in the symbol location, the reflected scan line
would miss the front surface of the engine. See Figure 2-3 on page 2-7 for maximum
angles.
5. If a window is to be placed between the engine and the symbol, the determination of
optimum symbol location should be made with a representative window in the
desired window position. Read the sections of this chapter concerning window
quality, coatings and positioning.
6. Give the scan engine time to dwell on the symbol for several scans. Poor quality
symbols may not read on the first scan. When first enabled, the scan engine may take
two or three scans before it reaches maximum performance. Enable the scan engine
before the symbol is presented, if possible.
