Angle
Scanning angle is important for promoting quick decodes. When laser beams reflect directly back into the
scanner from the bar code, this specular reflection can "blind" the scanner.
The MC9500-K scans at a 15° angle which improves scanning ergonomics.
To avoid this, scan the bar code so that the beam does not bounce directly back. But don't scan at too sharp
an angle; the scanner needs to collect scattered reflections from the scan to make a successful decode.
Practice quickly shows what tolerances to work within.
•
Hold the MC9500-K farther away for larger symbols.
•
Move the MC9500-K closer for symbols with bars that are close together.
NOTE Scanning procedures depend on the application and MC9500-K configuration. An application may use
different scanning procedures from the one listed above.
Linear Scanning
Ensure that a scan enabled application is loaded on the MC9500-K.
1.
Aim the exit window at the bar code.
2.
Press the scan button. Ensure the red scan beam covers the entire bar code. The Decode LED lights red to
3.
indicate that scanning is in process, then lights green and a beep sounds, by default, to indicate the bar code
was decoded successfully.

Imaging
MC9500-K with an integrated imager have the following features:
•
Omnidirectional (360°) reading of a variety of bar code symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
•
The ability to capture and download images to a host for a variety of imaging applications.
•
Advanced intuitive laser aiming for easy point-and-shoot operation.
The imager uses digital camera technology to take a digital picture of a bar code, stores the resulting image in its
memory, and executes state-of-the-art software decoding algorithms to extract the data from the image.

Operational Modes

MC9500-K with an integrated imager support three modes of operation, listed below. Activate each mode pressing
the Scan button.
•
Decode Mode: In this mode, the MC9500-K attempts to locate and decode enabled bar codes within its field
of view. The imager remains in this mode as long as you hold the scan button, or until it decodes a bar code.
