DS2200

3 READING FEATURES

The number of scans performed on the code by the DS2200 and therefore the

decoding capability 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 16 - "Step Ladder" scanning mode

If scanning is perpendicular to the code motion direction (Figure 16), 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
