Function code F65 options may also be used if there is a decline in bar
code readability (read rate) during normal document processing. If this
occurs, the following steps will assist you in diagnosing the problem:
1. Perform test option 3=Read Rate.
This test determines whether or not the reduction in readability is
caused by a deficiency in the equipment.
− If the resulting read rate is significantly lower than the
benchmark given, contact Service.
− If the resulting read rate is equal to or greater than the
benchmark given, proceed to Step 2.
2. Perform test option 1=EVALUATE.
This test evaluates the bar codes being used in terms of
dimensional and print clarity. Deficiencies in any one or more of
these criteria could result in a reduction in the overall read rate.
