Using the QC890 Verifier
The QC890 Verifier offers a choice of Automatic, 3, 5, 6, and 10 mil aperture
settings. External devices (i.e., mouse wands, pen wands, and linear imagers)
are available with apertures designed to match the most common X dimensions.
Wands are available with apertures of 3 (Mouse Wand only), 5, 6, 10, and 20
(Mouse Wand only) mil. These aperture sizes correspond to those specified in
ISO/IEC 15416 Barcode Print Quality Test Specification - Linear Symbols. The
proper aperture should be selected based on the X dimension range shown in
the table in the Pen/Mouse Wand Aperture Selection (page A-1) section.
Choosing an inappropriate scanning aperture results in inaccurate quality
measures. Too small an aperture may detect reflectance non-uniformities (spots
and voids) that would not affect scanning with a "normal" aperture size. Too large
an aperture will not be able to resolve individual elements of the symbol.
Scan Button
The scan button on top of the unit wakes the unit from power down. A first press
of the button turns on illumination and a second press activates reading
capabilities.
Scan Button LEDs
• Red LED - error conditions
• Green LED - good symbols and configuration changes
