Scanning Configurations
One common problem is incorrect configuration setup. You may be trying
to read a bar code with the check digit enabled, but the bar code was printed
without it. The default settings for the reader are the most frequently-used
parameters. If these work, use them. That way, when someone inadvertently
changes the settings, they can be reset by entering the return to default codes.
If you must use different settings, it is advisable to make a master sheet with
the desired configuration keystrokes in the proper order. The operator can
then enter the sequential order to return to the original configuration.
Is the proper bar code symbology enabled?
Each symbology is individually enabled or disabled. It is sometimes desirable
to enable only those that will be used, thereby eliminating any errors due to
the operator scanning the wrong bar code symbol.
Does the selected symbology format options match the symbol?
The scanned data from each bar code symbology can be restricted to elimi-
nate the scanning of unwanted symbols. The restrictions are individually set
for each symbology.
Is the reader able to read bar codes?
The Omni is available in magnetic stripe-only and bar code-only versions,
as well as in a combo version that read both bar codes and magnetic stripes.
Please check the model number with your supplier to make sure the Omni is
configured to read the media you want it to read.
