Scanning with the 2D Area Imager
The CN30 Computer has the 2D area imager, which provides the ability to
scan 2D bar code symbologies and supports omni-directional (360°) scan-
ning where you can position the CN30 Computer in any orientation to
scan a bar code label. Using the 2D area imager is very similar to taking a
picture with a digital camera.
1 Press (I) to turn on the CN30 Computer.
2 Point the scanner window at the bar code label and hold the CN30
Computer steady a few inches from the label.
3 Press the Scan button on the keypad or pull the trigger on a handle and
center the red aiming beam over the bar code label. The aiming beam is
smaller when the imager is closer to the bar code and larger when it is
further away.
When the CN30 Computer successfully reads a bar code label, you hear
a high beep and the green Good Read light turns on briefly.
4 Release the Scan button.
If you have problems scanning a bar code with the 2D imager, try following
some of these tips to improve the performance of your imager:
• Set Lighting mode to Illum LED Priority.
• Keep your hand as steady as possible while scanning a label.
• Make sure that Aimer LED Duration is set to zero.
• Position the imager as close to the bar code as possible while still being
able to capture the entire bar code.
• Enable only the bar codes that you need to use every day.
Use Intermec Settings to configure these imager commands. For help using
Intermec Settings, see “Configuring the CN30 Computer With Intermec
Settings” on page 46. For more information on the commands and their
parameters, see the Intermec Computer Command Reference Manual (P/N
073529) via the Intermec web site. See “Before You Begin” for information
