Scan Report
IMPROTANT To print a Scan Report, Telemetry Data must be set to
Full Report.
This executable menu item prints a diagnostic printout of bar code analysis parameters
calculated by the validator. It allows you to determine which parameter may be the
cause of bar code verification failures. The report printed is based on the last Full Report
received from the validator. This allows you to send a bar code print job to the printer,
have the bar code scanned by the validator, and view a report of the parameters as
seen by the validator.
For forms with multiple bar codes, only information from the last scanned bar code will
be included in the report. To view validator parameters for all bar codes on a form, use
the Online Data Validator Data Manager software.
NOTE:
The printed report is generated from validator reports received by the printer during
printing. The report does not include information about bar codes that are placed in the
validator scanning beam while the printer is idle or from print jobs that generate an
"Unscannable: xx Missing Codes" error message.
The number of Total Scans and Good Scans can help you determine if the print speed is
set too high and causing borderline failures by not allowing for enough scans to be done
by the validator. The Scan Report is based on the last Full Report received by the
validator. So if the last bar code printed is positioned close to the last inch of the form,
and on-demand printing occurs to force the last bar code to be fed past the laser beam,
the Total Scans and Good Scans reported will not be the same as those reported by the
validator when printing at the set Print Speed (in the QUICK SETUP and MEDIA
CONTROL menus). This is because the on-demand printing portion is done at a fixed
print speed which may be higher or lower than the set Print Speed. For example, a bar
code printed at 7 ips may yield eight Total Scans, but if printed in an on-demand printing
mode it may yield 18 Total Scans.
