3.2 DECODING CAPACITY IN LINEAR MODE
When in Linear Reading mode, the number of reads performed by the
DS4300 and therefore the decoding capacity, is influenced by the following
parameters:
•
number of scans per second
•
code motion speed
•
label dimensions
•
scan direction with respect to code motion
At least 5 scans during the code passage should be allowed to ensure a
successful read.

Figure 3.5 - "Step Ladder" scanning mode
If scanning is perpendicular to the code motion direction (Figure 3.5 - "step
ladder" mode), the number of effective scans performed by the reader is
given by the following formula:
SN = [(LH/LS)
*
SS] - 2
These symbols signify:
SN = number of effective scans
LH = label height (in mm)
LS = label movement speed (in mm/s)
SS = number of scans per second
