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.

3.2.1 Step Ladder Mode

Code motion

moving at LS speed

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
