DX8210 Barcode Scanner
Minimum Code Height for Advanced Code Reconstruction
Based on the scanner read rate of 1000 scans/sec., minimum label heights at
different conveyor speeds are given in the tables below.
Refer to the reading diagrams in
section
for further details on the reading fea-
tures. These diagrams are taken on various resolution
sample codes at a 25 C
ambient temperature depending on the conditions listed under each diagram.
•ANSI Grade B minimum
• 1000 scans/sec
The following tables describe the requirements for standard applications.
