5.3 Scanning through Automatic Label Recognition

In auto sensing mode (including auto sensing operation in auto stand mode) there is no need to operate the trigger switch;
approach the scanner with the code and the illumination light comes on making scanning available. This mode is used when
the scanner is sitting in the stand and the codes are brought up to the scanner for scanning.
The illumination light comes on when the codes are brought within the scanning field, or codes within the field are moved. If
a code is removed from the scanning field or codes within the scanning field are not moved for approximately three seconds,
the illumination light will go out.
In auto stand mode, the scanner operates in auto sensing mode after the power is turned on.
If the trigger switch is pulled during auto-sensing operation, the scanner enters auto-off mode and scanning can be carried out
using trigger switch operations. Switching from auto-off mode to auto sensing mode can be done manually or automatically,
and the preferred option can be selected in configuration software (ScannerSetting_2D).
- Manual
If the trigger switch is pulled three times within approximately one second while the scanner is operating in auto-off mode,
the scanner switches to auto sensing mode.
- Automatic
The scanner automatically returns to the auto sensing mode when, after switching to auto-off Ready state, the trigger switch
is not pulled for longer than the time specified for the scanner to return to the auto sensing mode.
The auto sensing return timing can be set using the configuration software (ScannerSetting_2D).
Auto sensing mode and auto stand mode can be selected using the QR-coded parameter menu or configuration software
(ScannerSetting_2D).
The level of sensitivity of the scanner to the code can be set to "high," "medium," or "low." For example, if the illumination
light is slow to come on when the code is brought up to the scanner, set the code sensitivity level to "high." Select the
sensitivity level in the configuration software (ScannerSetting_2D).
Note: Even if there is no code in the scanning field, the illumination light may come on if the brightness of the room
changes or if shadows in the scanning field move.
Note: Ambient illumination of 500 Lx or more is necessary for auto sensing mode to work properly.
