•
number of scans = [ (scan width - code width) x scan rate / pass-through speed ] - 2
Example: scan width = 20 cm code width = 10 cm scan rate = 450 scans / sec
conveyor speed = 1 meter / sec (100 cm / sec)
[ ( 20 - 10 ) * 450 / 100 ] - 2 = 43 so there will be 43 full scans on the code
The code width value will vary slightly according to the degree of tilt and pitch.
•
increase the scan width (adjust the reading distance) and decrease the code width and
pass-through speed to increase the number of scans
Remain within the product specifications for reading distance and barcode density
provided in Appendix A.
