Bar Code Capture With Linear Imager; Figure 79: Scanning; Figure 80: Aiming Pattern - Motorola TC55CH User Manual

• Scan 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.
• To avoid this, scan the bar code so that the beam does not bounce directly back. But do not 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 device farther away for larger symbols.
• Move the device closer for symbols with bars that are close together.
Note: Scanning procedures depend on the application and device configuration. An application may use
different scanning procedures from those described.

Bar Code Capture with Linear Imager

To capture bar code data:
Procedure:
1 Ensure that an application is open on the TC55 and a text field is in focus (text cursor in text field).
2 Point the top of the TC55 at a bar code.

3 Press and hold the Programmable button. The LED lights red to indicate that data capture is in process.
4 Place the red aiming pattern across the bar code. The LED lights green and a beep sounds, by default, to indicate
the bar code was decoded successfully.
