DS1100

3 READING FEATURES

The number of scans performed on the code by the DS1100 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

Typically, 5 scans should be allowed during the code passage to ensure a successful

read.

3.1 STEP-LADDER MODE

Figure 18 - "Step-ladder" scanning mode

If scanning is perpendicular to the code motion direction (Figure 18), 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
