READING FEATURES

4.2.1 Step-Ladder Mode

If scanning is perpendicular to the code motion direction (Figure 44), the number of effective

scans performed by the reader is given by the following formula:

SN = [(LH/LS)

SS] – 2 Where: SN = number of effective scans

LH = label height (in mm)

LS = label movement speed in (mm/s)

SS = number of scans per second

Direction of code

movement at LS speed

DS2100N

Laser beam

Figure 44 - "Step-Ladder" Scanning Mode

For example, the DS2100N (500 scans/sec.) for a 25 mm high code moving at 1000 mm/s

performs:

[(25/1000)

500] - 2 = 10 effective scans.
