Problems Reading Bar Codes

Solution
Make sure that:
•
the User Name and Password parameters on the CN4
must match the user name and password on
authentication server. You may need to reenter the
password on both the CN4, authentication server.
•
on your authentication server, the user and group are
allowed and the group policy is allowed to log into the
server. For help, see the documentation that shipped
with your authentication server software.
•
the IP address and secret key for access point must
match the IP address and secret key on the
authentication server. You may need to reenter the IP
address and secret key on both your access point and
authentication server.
•
the authentication server software is running on the
server PC.
Date and time are not saved when you perform a clean
boot. Reenter the date and time, and then save your
changes.
Solution
•
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 reading the bar code label "straight on."
Change the reading angle and try again.
•
The imager hardware trigger might be disabled in
Intermec Settings. To check the setting go to Start >
Settings > System Tab > Data Collection > Scanner
Settings. Hardware trigger should be checked.
Set the Scanner Model command to the specific attached
input device. Check enabled bar code symbologies and
enable only the symbologies being used.
