Scanning Method - Casio DT-X8 Series Software Manual

2.2.2 Scanning Method

The Laser Scanner has "scanning state" (emits laser beam to read a bar code) and "standby state"
(scanning is halted and in standby state). These two states are controlled to start scanning bar code
and stop the scanning.

Notes:
1.
The scanning method set by default is with "Continuous scanning (controlled with
Trigger key)" and "No. of preset times for continuous scanning = 1".
2.
In condition where the parameter in the registry has been set, performing a full reset on
the terminal makes emitting the laser beam is turned off intermittently between laser
emissions possible.
The path of the registry is as follows.

Description
Press Trigger key to start
scanning. Scanning is
stopped when either
scanning is succeeded or one
of the scan end conditions
(right side) is met.
Press Trigger key to start
scanning, and scanning will
continue as long as the
Trigger key is held down.
Scanning will stop when
either scanning is completed
for just preset no. of times
for scanning or one of the
scan end conditions (right
side) is met.
Scanner library functions are
used to start and stop
scanning. The previous
scanning data and scanning
data overlapped with other
scanning data will be
disregarded. Also, to save the
power during scanning,
emitting laser beam will be
turned off between laser
emissions. (note 2)
