How To Scan a Bar Code

Note: The function to use an imager like a camera (or for OCR decoding) is not supported. Using a Continuous Scan option, if
available, to scan programming bar codes is not supported.
The linear bar codes in this guide were created using Code 128 symbology. Your Marathon has been set up to automatically
read / decode Code 128 bar codes.
Using the bar codes contained in this guide, you can change bar code reader system parameters or reset all parameters to their
factory default values.
All bar code reader parameters are programmed into and stored by the bar code reader engine.
Note: If this guide is not in print form, locate the page in this electronic guide that contains the bar code you wish to use. Print
the page on white paper using a 600dpi laser printer (or equivalent).
Note: Print the page containing the Reset and Cancel bar codes as well as the page containing the A – F and 0 – 9 number bar
codes.
Select the parameter you want to scan. If this guide is in print form, lay it flat on a table or propped up at an angle.

Scan a Linear Bar Code

Holding the beam aperture approximately 3 – 12 inches away from the bar code, aim the scan aperture toward the selected
bar code. Refer to the imager engine type in Decode Zones later in this guide for recommended decode ranges.
Press the Scan button. Align the scan beam so that the bar code is centered within the beam. The beam must cross the
entire bar code. Move the bar code reader towards or away from the bar code so that the bar code takes up approximately
two-thirds the width of the beam.
Refer to the recommended decode zones for the installed bar code reader engine if you are having difficulty with this pro-
cess.
Note: Do not position the scan aperture exactly perpendicular to the bar code being read. In this position, light can bounce back
into the scan aperture, and possibly prevent a successful decode.

Scan a 2D Bar Code

To scan a bar code with the imager, point the beam aperture at a bar code and press the Scan button. You will see a brack-
eted cross-hair strike the bar code.
Holding the beam aperture approximately 3 – 12 inches away from the bar code, aim the imager aperture toward the
selected bar code. Press the Scan button and you will see a bracketed cross-hair strike the bar code.
Align the brackets so that the center (or one of the four corners of the bar code's center box) of the bar code is covered by
the cross-hair. Refer to bar code decoder engine Decode Zones later in this guide for recommended scan ranges for your
device.
