• “Scanner Status LED, Sounds, and Vibrations” on page 2-17 details how to interpret whether or not a

barcode has been successfully scanned.

• Barcode Parameters: Appendix C: “Scanner Settings”.

• Imager Settings: Appendix B: “Imager & Camera Settings”.

• “Troubleshooting” on page 2-17 provides some helpful suggestions should the scan fail.

Scanner types include:

• Long Range: reads large 1D barcodes (55 mil) at long distances (up to 3m).

• Standard Range/High Performance: reads damaged or low contrast regular 1D barcodes (5 - 55mil) at

medium distances (up to 1m).

• Extended Range: reads regular 1D barcodes (5 - 55mil) at short to medium distances (1m), as well as

large 1D barcodes (e.g. 55 mil) at long distances.

• 1D Imager: reads regular 1D and PDF417 barcodes at short to medium distances.

• EA11 2D imager: reads 1D and 2D barcodes including damaged and low contrast regular 1D barcodes;

smallest barcode at 5 mil with a minimum read distance to 2.8 in. / maximum read distance of 5.1 in.;

largest barcode at 40 mil with a minimum read distance of 3.1 in. / maximum distance of 32.4 in.

• EA20X 2D imager: reads 1D and 2D barcodes including damaged and low contrast regular 1D barcodes;

shortest barcode at 6 mil with a minimum read distance of 6.1 inches / maximum read distance of 9.1

inches; longest barcode at 40 mil with a minimum read distance of 5.1 inches / maximum read distance of

49.2 inches.

• SE4600LR imager: captures digital images for transmission to a decoder to decode a barcode of any

format supported by the decoding software. Uses laser aiming, LED illumination, and CMOS sensors to

capture barcode images over an extended range and under a wide variety of lighting conditions.

Basic Scanner Operations

• Turn the hand-held on. Wait until the unit has booted up completely.

• Aim at the barcode and press the scan key or the trigger. A scan beam and a warning indicator appear until

a successful decode is achieved or six seconds have elapsed.

Scanning Techniques

• Hold the scanner at an angle. Do not hold it perpendicular to the barcode.

• Do not hold the scanner directly over the barcode. In this position, light can reflect back into the scanner

exit window and prevent a successful decode.

• Scan the entire barcode. If you are using a 1D or PDF laser scanner, make certain that the scan beam

crosses every bar and space on the barcode, including the margins on either end of the symbol.

• If you are using a 2D imaging scanner, make certain the red, oval shaped framing mark is centered within

the barcode you want to scan.

• When using imaging scanners, do not move the scanner while decoding the barcode. Movement blurs the

image.

• Hold the scanner farther away for larger barcodes.

• Hold the scanner closer for barcodes with bars that are close together.
