Operation Modes
area imager
FuzzyScan family A series array imager supports various operation modes,
including trigger, presentation, alternative, level, force, toggle, diagnostic, low
power and multiple read modes. The details of each operation mode are
listed below for reference.
Trigger Mode
When trigger mode is selected, the scanner goes into standby state after
scanning the bar code. You must press the trigger switch to turn on the light
source of the scanner before scanning the bar code.
Presentation Mode
When presentation mode is selected, the scanner is preset to turn on the
background lighting to detect the bar codes. Once the scanner detects an
image similar to a bar code, it will try to decode the bar code immediately.
Alternative Mode
When alternative mode is selected, the scanner keeps the light source on till
the preset “light source on time” is up. After turning off the light source, you
must press the trigger switch to turn on the light source again. After each
good read, the timer counter of light source on time is reset. You do not have
to press the trigger switch frequently. It is very useful for multiple scanning.
Level Mode
When level mode is selected, the scanner continues to turn on the light
source till a bar code is decoded or preset “light source on time” is up.
When a bar code is decoded successfully, the scanner turns off the light
source immediately. After the scanner turns off the light source, you have to
press the trigger switch to turn on the light source again. If there is no
scanning operation performed during the preset “light source on time”, the
scanner will turn off the light source after the preset light source on time is up.
