VALIDATOR
Number of Codes
This menu tells the printer how many codes to expect on a form. It is required
in conditions where the host sends bitmapped graphics to the printer to
produce bar codes. Therefore, the printer does not know how many codes to
expect and cannot tell when a code is skipped. With this figure set to a
specific number, the printer can check after a form has printed and passed the
validator, whether or not it has received enough analysis reports. If it does not
have at least as many reports as it expects, it can assume a gross bar code
failure. When Auto is selected, the printer will only expect as many bar code
analysis reports as bar codes printed using printer bar code commands.
The options are Auto (the factory default) and 1-99.
Validator Action
This menu defines the action the printer will take in the event of an error. See
the Validator User's Manual for details.
The options are Retry Form (the factory default), Stop, and Overstrike.
Symbol Contrast
This item selects whether or not symbol contrast is included as part of the
pass/fail criteria. The precise percentage to be sent to the validator is
determined by the type of printing selected. See the table below.
The options are Enable (the factory default) and Disable.
Disable
Thermal Transfer
Direct Thermal
Quiet Zones
This item enables or disables all checking of the quiet zones.
The options are Enable (the factory default) and Disable.
Min. Code Height
This menu tells the printer the closest vertical gap between bar codes that
needs to be resolved. Refer to the Print/Slew Speed Limits for background
information. The printer's ability to resolve which form contains the bad bar
code is a function of print speed and the closeness of bar codes on separate
forms. The default setting can resolve very small forms, but limits print speed.
If you know that the bar codes are far enough apart and far enough from the
bottom of a form, you can increase this value to allow for faster printing.
The range is 0.13 to 1.00 inches adjusted in .01 inch increments.
The factory default is 0.25 inches.
