Note: When using the external QC3800VE linear imager, it does not report ISO/
IEC reflectance parameters; therefore no calibration is necessary or
possible.
Scanning Properly Using the QC3800VE Linear Imager:
1. The best reading position for the QC3800VE linear imager is 6 inches
(150mm) from the surface of the barcode to the face of the scanner, with an
angle of incidence of 15 degrees from perpendicular. At this orientation, the
system performance approximates an average circular aperture size of .006
to .008 inches (.152 to .203 mm). Extreme variations from this orientation
may negatively affect the accuracy of some parameter results.
2. Scanning is initiated by squeezing the trigger on the linear imager. Hold the
trigger down until the beam shuts off.
3. Listen for an audible tone. When the unit scans and decodes a barcode, it
emits a single beep.
• If the unit cannot decode a barcode after a trigger pull, it will not beep and
no results are displayed.
• After a successful decode, with a result that passes the minimum
acceptable grade, the unit emits another beep of the same tone.
• A decode that fails to receive a grade above the minimum requirement
causes the unit to emit a beep of a different tone.
Note: The QC3800VE reading width (includes quiet zones) is 6 inches.
The QC3800VE is the only device that can be used as a non-contact input
device with a QC890 Verifier unit.
The QC3800VE should not be used with any decoders, terminals, or other
brand of verifiers.
