Scan LED Indicators

The red/green Scan LED Indicators (located in the Indicator LED Bar and in the rotating turret) indicates the scan status. For the

location of the Scan LED Indicators see, Figure 1-1 on page 1-4.

Scanning Considerations

Scanning consists of; aim, scan and decode. Scanning performance can be optimized by considering the range and the scanning angle:

• Range

Any scanning device decodes well over a particular working range (minimum and maximum distances from the bar code).

This range varies according to bar code density and scanning device optics.

Scanning within range brings quick and constant decodes; scanning too close or too far away prevents decodes. Move the

scanner closer and further away to find the right working range for the bar codes being scanned. However, the situation is

complicated by the availability of various integrated scanning modules. The best way to specify the appropriate working

range per bar code density is through a chart called a decode zone for each scan module. A decode zone simply plots working

range as a function of minimum element widths of bar code symbols.

• Angle

The scan angle is important for optimizing decode performance. When laser beams reflect directly back into the scanner

from the bar code, this specular reflection can “blind” the scanner.

To avoid this, scan the bar code so that the beam does not bounce directly back. But do not scan at too sharp an angle; the

scanner needs to collect scattered reflections from the scan to make a successful decode. Practice quickly shows what

tolerances to work within.

Contact the Symbol Support Center if chronic scanning difficulties develop. Decoding of properly printed bar

codes should be quick and effortless.

Laser Decode Ranges

The decode ranges provide the decode ranges for barcodes of specified densities. Figure 2-15 shows the laser decode ranges and

Table 2-7 on page 2-18 lists the scan ranges for the selected bar code densities. The minimum element width (or “symbol density”)
