Scanning PDF417 (2-D) Bar Codes with the EP1

The EP1 is capable of scanning 2-dimensional bar codes. To scan a 2-dimensional PDF417 bar code:

1.) Aim the scanner at the PDF bar code and press the trigger.

2.) Hold the trigger down and keep the scan line parallel to the rows of the symbol

3.) Manually raster the scan line by slowly moving the scanner up and down so it scans the entire barcode at a

rate of one inch per second.

The PDF decode feedback should be enabled upon arrival. With this feature, a clicking noise lets you know the

bar code is being decoded. If you do not hear the clicking noise when you’re scanning the bar code, it’s not

being scanned properly.

To improve PDF decoding:

• Check that PDF417 scanning is enabled.

• Make sure the scan line extends at least ½” past the left and right edges of the bar code.

• Hold the scanner closer for denser symbols, farther away for larger symbols.

• Make sure you scan the top and bottom rows of the symbols.

• Be patient – it may take a few swipes to decode the symbol.

The bar code has been completely decoded when you hear a tone, followed by a short high tone beep. The

green LED stays lit for two seconds or until the next trigger pull.
