Scanning with the 4685-L0D scanner
With two scan windows, the 4685-L0D scanner can be easily adapted to either
fixed/portable or targeted handheld scanning. The front scan window, with its mul-
tiple scan pattern, is used for most retail items. The rear scan window emits a
single targeted scan pattern for handheld scanning of bar codes on hard-to-read or
bulky items, or to read an individual bar code among many bar codes.
Fixed-mode scanning
Fixed-mode scanning provides ease of use by reducing the need to pick up the
scanner to read a bar code. A specially designed scan pattern minimizes the need
for the operator to position the item for scanning.
The scanner stand can be adjusted forward and backwards as needed. For most
applications, the best scanning position is straight up and down. Figure 5-1 shows
the range of movement.
Optimal position for most applications
Figure 5-1. Adjustments of the scanner position
To use the scanner in fixed mode, place the scanner into the stand and make sure
it is seated securely. In this mode, the scanner can read bar codes in either the
sweep mode or the presentation mode.
