Marker - Denso GT20Q-SB User Manual

8.4 Marker

The red semiconductor laser illuminates to indicate the scanning area as a guide.
Using the QR-coded parameter menu or configuration software (ScannerSetting_2D), select one of the three following modes.
8.4.1 Normal Marker Mode
When the trigger switch is in auto-off mode or auto stand mode auto-off
The marker beam illuminates continuously while the trigger switch is held down.
When the scanner is ready (that is, within approximately five seconds of pulling the trigger switch or until completion of
scanning), the marker beam illuminates continuously. The marker beam turns off when five seconds have elapsed in the
Active state after the trigger switch is pulled, when scanning is successfully completed, or when the trigger switch is released.
When the trigger switch is in Momentary switching mode or Alternate switching mode
In Momentary switching mode, the marker beam illuminates continuously while the trigger switch is held down.
When the scanner is ready (while the trigger switch is held down in Momentary switching mode or the scanner is in the
Active state in the Alternate switching mode), the marker beam illuminates continuously.
When the scanner is on standby (while the trigger switch is released in Momentary switching mode or when the scanner is in
the Ready state in the Alternate switching mode), the marker beam turns off.
When the trigger switch is in momentary switching mode (Reverse type)
In Momentary switching mode (reverse type), the marker beam illuminates continuously when the trigger switch is released.
When the scanner is ready (when the trigger switch is released in Momentary switching mode (reverse type), the marker beam
illuminates continuously. When the scanner is on standby (when the trigger switch is pulled in Momentary switching mode
(reverse type)), the marker beam turns off.
When the trigger switch is in Continuous reading mode 1 or 2
When the scanner is turned on, the marker beam illuminates continuously.
The marker beam turns off when it receives a "Z", "READOFF" or "LOFF" command, and illuminates continuously when it
receives an "R", "READON" or "LON" command.
When the trigger switch is in Auto sensing mode or performing auto sensing in Auto stand mode
The scanner detects code-like items entering the scanning field, and switches the scanner to the Active state, illuminating the
marker beam continuously. The marker beam will turn off after three seconds have elapsed following successful scanning
completion or when scanning is not completed successfully after then scanner has switched to Active state and three seconds
have elapsed.
8.4.2 Marker-OFF Mode
The marker beam will not illuminate under any conditions.
8.4.3 Marker-ON Mode
When the scanner enters Ready state, the marker beam illuminates continuously for approximately 30 seconds before turning
off.
The marker beam illuminates continuously when it is ready to scan.
