Problems While Scanning Bar Codes

Problem
You cannot see a red beam of light
from the scanner when you press
the Scan button or one of the
Side Scan buttons and aim the
scanner at a bar code label.
When you release the Scan but-
ton or Side Scan button, the
Good Read light does not turn
off.

Solution
You may have gone out of range of an access point.
Try moving closer to an access point or to a different location to re-establish
communications. Once you are in range again, the network connection icon
appears again. Any data you collected while out of range is transmitted over the
network.
The no network connection icon appears in three situations:
• The CN2B Computer may not have an IP address. You must configure an IP
address for the CN2B Computer or make sure that DHCP assigned an
address. Use Intermec Settings and select the radio tab to make sure an IP
address is assigned.
• The CN2B Computer may not be connected to the access point. Try these
possible solutions in order:
• Make sure the access point is turned on and operating.
• Make sure you are not using the CN2B Computer out of range of an
access point. Try moving closer to an access point to re-establish commu-
nications.
• Make sure the CN2B Computer is configured correctly for your network.
The radio parameters on the CN2B Computer must match the values set
for all access points the CN2B Computer may communicate with.
• If you have an 802.11b/g radio, the radio initialization process may have
failed. Try resetting the CN2B Computer.
• If you have tried these possible solutions and the no network connection icon
still appears, you may have a defective radio card. For help, contact your local
Intermec representative.
Solution
There are three possible problems:
• You may be too far away from the bar code label. Try moving closer to the bar
code label and scan it again.
• You may be scanning the bar code label "straight on." Change the scanning
angle and try again.
• The PSM files may not be correctly installed.
You can test the effective range of the scanner. Move within 61 cm (2 ft) of a wall
and test the scanner. You need to be within the scanning range to scan bar code
labels.
The Good Read light remains on if you configure the CN2B Computer to use
continuous/edge triggering. If you configure the CN2B Computer for level trig-
gering and the Good Read light remains on, there may be a problem. Press the
Scan button or one of the Side Scan buttons again without scanning a bar code
label. If the light is still on, contact your local Intermec service representative.
