Marker beam

The red marker beam (semiconductor laser) comes on to indicate the scanning area as a guide.
The marker provides a choice of the three modes--Normal marker mode, marker-OFF mode and marker-ON mode
that can be selected by using the QR-coded parameter menu or the configuration software (ScannerSetting_2D).
(1) Normal marker mode
The following description assumes that "Marker" is specified for the halfway position of the trigger switch and
"Scan" for the fully depressed position.
When the trigger switch is in auto-off mode:
Holding down the trigger switch halfway turns on the marker beam for approx. 30 seconds. When the scanner is
ready to scan (that is, within approx. 5 seconds from the full depression of the trigger switch or until completion of
reading from that), the marker beam remains on. If you release the trigger switch when the scanner is ready, the
marker beam will go off.
When the trigger switch is in momentary switching mode or alternate switching mode:
In the momentary switching mode, holding down the trigger switch halfway turns on the marker beam for a
maximum of 30 seconds.
When the scanner is ready to scan (that is, while the trigger switch is fully held down in the momentary switching
mode or when the scanner is ready to scan in the alternate switching mode), the marker beam remains on. When the
scanner is on standby (that is, the trigger switch is released in the momentary switching mode or when the scanner is
on standby in the alternate switching mode), the marker beam will go off.
When the trigger switch is in continuous reading mode 1 or 2:
Turning the scanner on activates the marker and keeps it on.
If the scanner receives the Z, READOFF or LOFF command, it turns off the marker beam; if it receives the R,
READON or LON command, it keeps the marker beam on.
When the trigger switch is in auto sensing mode
When the scanner senses a code coming into the readable area and becomes ready to scan, it automatically turns on
the marker beam. After approx. 3 seconds from completion of scanning or if scanning is not completed within approx.
3 seconds, the scanner switches to standby and turns off the marker beam.
(2) Marker-OFF mode
The marker beam will not come on under any conditions.
(3) Marker-ON mode
When the scanner switches to standby, the marker beam is turned on for approx. 30 seconds.
When it is ready to scan, the marker beam remains on.
