3.2.2 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.
Table 3.21 Scanning methods
Scan method Description Conditions for scanning to end
Timeout
Yes/No
Single scan
Press the trigger key to start
scanning. Scanning is stopped
when either scanning is
succeeded or one of the scan end
conditions is met.
- Timeout time has elapsed.
- OBRClose function is called.
Yes
Continuous scan
(controlled with
trigger key)
Press the trigger key to start
scanning, and scanning will
continue as long as the trigger
key is pressed down.
Scanning will stop when either
scanning is completed for just
preset no. of times for scanning
or one of the scan end conditions
is met.
- Timeout time has elapsed after scanning
a bar code.
- Scanning for the number of preset times
is complete.
- The trigger key is released.
- OBRClose function is called.
Yes
Continuous
scanning
(controlled by
program)
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. (see
note)
- Timeout time has elapsed after scanning
the precious scanning.
- Scanning end function is called while
scanning continues.
- OBRClose function is called.
Yes
Note:
The scanning method set as default is with “Continuous scanning (controlled with trigger key)”
and “No. of preset times for continuous scanning = 1”.
Step Scan
This method is for scanning a designated number of bar codes. Once scanning for the designated
number of bar codes has been completed, the scanner will close and not scan again until reopened.
Also, the same bar codes that have been scanned previously cannot be scanned again.
