Imager Scanning
3.
Press the scan button.
The red laser aiming pattern or aiming dot turns on to assist in aiming. Ensure the bar code is within the
area formed by the brackets in the aiming pattern or close to the aiming dot. The aiming dot is used for
increased visibility in bright lighting conditions.
The Scan/Decode LED lights red to indicate that scanning is in process, then lights green and a beep
sounds, by default, to indicate the bar code was decoded successfully. Note that when the MC55 is in Pick
List Mode, the imager does not decode the bar code until the crosshair or aiming dot touches the bar code.

NOTE
Imager decoding usually occurs instantaneously. The MC55 repeats the steps required to take a digital
picture (image) of a poor or difficult bar code as long as the scan button remains pressed.
