Reading Codes

Be sure to charge the battery cartridge loaded in the scanner with the dedicated charger before using the scanner for

the first time or after an extended period of disuse. (For the charging procedure, refer to Chapter 9.)

(1) Bring the reading window to a target code and press the trigger switch. The marker beam comes on, indicating the

scan range. Align the center of the marker beam with that of the target code.

(This step is not required for continuous reading modes 1, 2 and auto sensing mode.)

(2) Wait for the indicator LED to turn blue and the beeper to sound, indicating a successfully read.

Note: The actual scan range is narrower than the marker range. The scan range is approx. 6cm (2.4") wide by 4cm (1.6")

high when the scanning distance is approx. 10cm (3.9").

Note: The marker range should only be used as a guide. It does not assure that a code within the marker range can be read.

Note: Allow only a single code to come within the field of view except when the multi-line code scanning is allowed.

Having more than one code within the field of view either causes the read to fail or produces multiple input.

Note: The double-read prevention enabled time can be specified with the configuration software (ScannerSetting_2D).

Note: The scanner can read codes omnidirectionally. Note that a target code plus its margin should lie within the scan

range.

Note: If the scanner fails to read due to specular effects or other factors, change the scanning angle of the reading window

or the distance from the codes, and repeat the process. (Specular effects occur when the reflection of the light from the

label surface is too strong, such as when the reflecting surface is polished or covered with vinyl.)
