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
