SE 2223/3223 Scan Engine Integration Guide
Mounting
On the bottom of the chassis there are three mounting holes (M2x0.4) and two locator
holes, shown in
Figure 2-1 .
The SE 2223/3223 may be mounted in any orientation with no degradation in performance.
Location and Positioning
Symbol Position with Respect to a Fixed-Mount Scan Engine
The SE 2223/3223 may need to be mounted to read symbols that are automatically
presented to it, or that are always presented in a pre-determined location. In these
situations positioning of the SE 2223/3223 with respect to the symbol location is critical, or
unsatisfactory reading performance may result.
Use the following steps to ensure satisfactory operation of the SE 2223/3223 in your
installation.
1. Determine the optimum distance between the scan engine and the symbol. Due to
the large variety of symbol sizes, densities, print quality, etc., there is no simple
formula to calculate this optimum symbol distance. Try this:
a. Measure the maximum and minimum reading range that can be achieved with
your symbols.
b. Locate the scanner so the symbols are near the middle of this range when being
scanned.
Check the near and far range on several symbols. If they are not reasonably
consistent there may be a printing quality problem that can degrade the
performance of your system. Symbol Technologies can provide advice on how
to improve your installation.
Table 2-5 and Table 2-6 provide general guidelines for bar code ranges.
