How to Scan

Quick Reference Guide 1-9

Troubleshooting

The scanner will automatically perform a set of self-tests whenever you

turn it on. If your scanner doesn’t seem to be functioning properly, fol-

low these steps to try and isolate the problem.

1. Is the power on? Does the illumination beam come on?

If no illumination beam, check that...

• all connections are fully seated and in the appropriate port(s).

• the host system power is on (if external power isn’t used).

• the trigger works.

2. Is the scanner having trouble reading your symbols?

If the scanner isn’t reading symbols well, check that the symbols...

• aren’t smeared, rough, scratched, or exhibiting voids.

• aren’t coated with frost or water droplets on the surface.

• are enabled in the scanner. See the Product Reference Guide

(PRG) for more about configuring the scanner to read symbolo-

gies).

3. Is the bar code displayed but not entered?

The bar code is displayed on the host device correctly, but you still

have to press a key to enter it (the Enter/Return or Tab key, for

example).

You need to program a suffix which enables the scanner to output

the bar code data plus the key you need (such as a carriage return

“CR”) to enter the data into your application. Refer to the PRG

for further information.

4. Does the scanner read the bar code incorrectly?

If the scanner reads a bar code, but the data is not displayed cor-

rectly on the host screen:

• The scanner may not be programmed for the appropriate termi-

nal interface. For example, you scan “12345” and the host dis-

plays “@es%.” Reprogram the scanner with the correct interface

selection bar code. See

Programming in this manual and/or the

PRG.
