Table 3-1
Problem
The omni-line scan pattern does not
display when the directions are
followed for installing the interface
cable on page 1-3.
Scan line(s) display, but bar code
cannot be read.
Bar code is decoded, but not
transmitted to the host.
Scanned data is incorrectly displayed
on the host.
NOTE If after performing these checks the symbol still does not scan, contact the distributor or call the local
Global Customer Interaction Center. See page xiv for contact information.
Possible Causes
No power to the scanner.
Interface cable is not
properly connected.
Scanner is not programmed
to read the bar code type.
Bar code is damaged.
Bar code is too far from
scanner.
The host has disabled
scanning or overridden
parameter settings.
Scanner is not programmed
for the correct host type.
Scanner is not programmed
to work with the host. Check
scanner host type
parameters or editing
options.
Possible Solutions
Ensure the host has power, and is on. If the
scanner uses a separate power supply, ensure
it's connected to a working AC outlet.
Check for loose cable connections.
Ensure scanner is programmed to read the bar
code type being scanned.
Try scanning other bar codes of the same bar
code type.
Move the bar code closer to the scanner.
See the technical person in charge of scanning.
Scan the appropriate host type bar code.
Ensure proper host is selected.
For RS-232, ensure the scanner's
communication parameters match the host's
settings.
For keyboard wedge, ensure scanner is
programmed with the correct country code and
that the CAPS LOCK key is off.
Ensure editing options (e.g., UPCE-to-UPCA
Conversion) are properly programmed.
