5.9.2 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 5.10
for further details on the reading features.
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.
