3.5 Examples and instructions on use
Do not set the toner density to the lowest contrast value. It is recommended that you
set it to a density of 3 or higher. The setting can be made using the control panel or
the PRESCRIBE sequence
!R! FRPO D4,3;EXIT;
The Toner Save mode should not be used when printing barcodes.
Where possible use white paper as this can enhance the contrast.
Carefully test your application. Have you selected the best settings for your printer
and in your programming and optimised them for the read devices being used? A
barcode application should always be viewed only as a whole in which all constituent
parts should be attuned to one another.
One frequent cause of read errors is selecting quiet zones that are too small. They
cannot be generated automatically by PCL Barcode Flash, but can only be done
manually by careful programming and/or positioning.
If the read device used allows and different symbols don't have to be read alternately
using the same device, you should permanently set the device to the symbology
being read. Particularly when reading matrix codes, automatic recognition of
barcodes and/or matrix codes should not be set as read speed will suffer as a result.
