MATRIX 320
STEP 3 - AIM AND AUTOFOCUS THE READER
Matrix 320 provides a built-in laser pointer aiming system to aid reader positioning. For
Liquid Lens models, the autofocus feature is also incorporated into this function. The
aiming system is accessed through the X-PRESS Interface.
1. Power the reader on. During the reader startup (reset or restart phase), all the
LEDs blink for one second. On the reverse side of the reader near the bracket, the
“POWER ON” LED (blue) indicates the reader is correctly powered.
2. Enter the Aim/Autofocus function by pressing and holding the X-PRESS push but-
ton until the Aim LED is on.
3. Release the button to enter the Aim function. The laser pointer turns on, and the
Autofocus procedure begins. The Aim LED will blink until the procedure is com-
pleted.
4. Place the Grade A Barcode Test Chart in front of the reader at the correct reading
distance for your application (see the Global FOV Diagrams for reference). The
center of the cross is 16 mm (14 LEDs model) or 30 mm (36 LEDs model) under
the optical axis
, as shown in Figure 6.
Within 3 seconds (before the reader flashes), center one of the larger codes on
the aiming system pointer (the code must not move during this procedure).
The Autofocus procedure ends when the Reading Distance and PPI values are suc-
cessfully saved in the reader memory, the Aim LED will stop blinking and Matrix
320 emits 3 high pitched beeps.
If the Autofocus cannot be reached after a timeout of about 3 (three) minutes,
Matrix 320 will exit without saving the parameters to memory, the Aim LED will
stop blinking and in this case Matrix 320 emits a long low pitched beep.
