Ver. Erase Zone
This menu defines the area above and below the bars that will be erased, regardless of picket fence or
ladder orientation. It is used when the barcode has extraneous data beyond the bars that need to be
deleted as it is being replaced.
The height of the area can be defined between 0 and 0.99 inches in 0.01 inch increments. The default is
0 inches (no empty space). This feature can be used to remove special attributes remainders of the
original barcode such as a guard bar or line that borders the top and bottom of the bars. It can also be
used to erase the original PDF if the user wants to force all PDFs to be replaced (see Update PDF on
page 200). The PDF occupies more than 1/6 of an inch.
Quiet Zone Fault
This menu defines whether a fault must be reported on the front panel LCD if the BCDOPT feature cannot
print the replacement barcode without violating the quiet zone as defined in the "Hor. Quiet Zone" menu,
where the width of the replacement barcode plus quiet zones is too large to fit the available white space
on the page.
•
Enable (factory default). If this fault occurs, reduce the quiet zone to see if the barcode fits.
•
Disable. Quiet zone violations are not reported, but adjacent page elements could be drawn too close
to replacement barcodes and possibly overlap.
Update PDF
There are two distinct cases with barcode PDFs. In the first case, the PDF is partially embedded in the
barcode such that erasing the bars also erases the PDF. In the second case, the PDF is printed entirely
above or below the barcode and is not disturbed by the barcode replacement.
Whenever the PDF is embedded in the barcode such that erasing the bars also erases the PDF, the
embedded PDF will be automatically detected and replaced. An area surrounding the barcode will be
erased to remove the portions of the former PDF that extended beyond the bounds of the original
barcode. The erase area is shown in the figure below. Since embedded PDFs are automatically replaced,
the Update PDF menu option has no effect on this type of PDF.
