11000 Scanner Installation Manual
3.2 - Reading Features
For example, the 11000 Scanner (scanning at 350 scans/s) for a 25-mm high code
moving at 500 mm/s performs:
SN = [(25/500) * 350] - 2 = 15 effective scans.

Figure 3.2 - "Picket Fence" Scanning Mode
If scanning is parallel to the code motion, (Figure 3.2 - "Picket Fence" Scanning
Mode), the number of effective scans is given by:
SN = {[(FW-LW)/LS] * SS} -2
Where: SN = number of effective scans
FW = reading field width (in mm or inches)
LW = label width (in mm or inches)
LS = label movement speed (in mm/s or inches/s)
SS = scans/s
For example, for a 50-mm wide code moving in a point where the reading field is
200 mm wide and the label is moving at 1500 mm/s, the 11000 Scanner (scanning
at 350 scans/s), performs
SN = {[(200-50)/1500] * 350} - 2 = 33 effective scans
