Programming the Scanner
3-28
Diagnostic Mode (Test Reading)
This operation mode is specifically designed for diagnostic purposes. When
this operation mode is selected, the light source of the scanner is forced on
without regard for other programmable parameters, such as double scan
verification, redundancy, and so forth.
Scanning Tolerance
(Printing Quality Control)
This parameter provides the user with a helpful tool to use
when the printing quality of the bar code is poor. This is a
programmable feature in IT3220 units with software revision
AXX, and 3060/80B with software revision CXX. Units using
later software revisions [IT3220 (revision BXX) and
VT3060/80B (DXX) scanners] perform this feature
automatically without any extra programming.
To reduce the error reading rate further, we also recommend
that you limit the number of enabled symbologies to only
those that you need to read, and to also limit the minimum and
maximum reading of each enabled bar code symbology.
