Using the QC200
Before you turn the unit on and select a mode of operation, you should review
the following to learn how to properly scan a bar code with it.
To scan a bar code:
1. Hold the QC200 as you would a pen or pencil. The raised “finger grip
ridges” on each side of the case near the optics/scanning tip are guides for
finger placement.
2. Press the optics tip lightly against the surface to be scanned in the clear
area (quiet zone) on either side of the bar code symbol. To maintain a
proper scanning angle, be sure both the optics tip and the “reflectance
guide” are flat on the surface to be scanned.
3. At about the same speed with which you would quickly underline one of the
sentences in this text, and without interruption, move the QC200 evenly
across the center (or approximate center) of the bar code.
4. Listen for a long beep tone quickly followed by a short beep tone signifying a
good read. Note that a long beep followed by three short beeps indicates an
error condition exists in the symbol scanned.
NOTE: Practice your scanning technique until you can successfully scan each of
the supplied test symbols on each attempt. Some of the supplied test symbols
have “intentional errors” in them to show the user how error conditions are
reported.
Power ON/OFF
The Quick Check
®
200 Series is turned on by pressing the POWER button, to
which it responds by emitting four quick beeps and first displays:
[QC2xx aa/lll]
where “xx” identifies the model number, “aa” is the aperture size designation in
“mils” (one thousandths of an inch) and “lll” is the spectral response or
wavelength of illumination in nanometers. If there are stored print records (and
the unit is connected to a Quick Check
®
AC Charger or Printer interface cable),
the display then changes to:
[BUF xx% Ful>]
or it may read “LOW BATTERY!” or “RECALIBRATE!” if charging or reflectance
calibration is needed.
