Chapter 3 Reading Bar Codes - Denso GT10B-SM User Manual

Chapter 3 Reading Bar Codes

(1) Press the trigger switch to turn on the illumination LED and prepare the scanner for reading.
Note: This step is not required for the continuous reading and auto sensing modes (see Section 5.3).
(2) Align the scanner over the center of the target bar code so that the illumination longitudinally scans the center of
the bar code.

(3) Wait for the indicator LED to turn blue and the beeper to sound, indicating a successful read.
Note: The effective scan range is less than the full illumination range.
The effective scan range depends on the model and the distance from the scanner to the target.
GT10B-SM/GT11B-SM: approximately 10 cm (3.94") for a scan distance of 7 cm (2.76")
GT10B-LM:
Note: Having more than one bar code within the field of view either causes the read to fail or produces multiple
input.
Note: Bar code orientation (right side up or upside down) does not matter as long as the margins are well within
the field of view.
Note: It is sometimes necessary to vary the scanning angle or distance to eliminate reflections of the illumination
and ambient light off highly reflective labels.

Successful completion of read-in produces data transfer.
The scanner transfers only data that matches a predefined list of acceptable bar codes.
(Refer to Chapter 7 for details.)
The scanner gives priority to reducing the time spent decoding bar code data.
The scanner gives priority to expanding the scan range.
