• You scan a bar code label to enter data at the DOS prompt, but the reader
beeps and displays an error message such as, "Bad command or filename."
Make sure the application that is expecting the data is running. If
necessary, start the application and scan the bar code again.
• Try using another scanner or wand.
• Scan the bar code again, but vary the scanning angle and distance.
• Clean the scanning window of
the laser scanner with a
solution of ammonia and water.
Wipe dry. Do not allow
abrasive material to touch the
window.
• Use IC.EXE to verify that the
reader is configured to read the
bar code symbology you are
scanning.
• Use IC.EXE to verify that the
correct scanner type is enabled
on the reader. For help, see the
"Scanner Devices" command in
Chapter 12.
• Verify that the command IF
EXIST D:\RDG.BAT CALL D:\RDG.BAT is executed from the
AUTOEXEC.BAT file. If the command is not executed, the reader cannot
decode bar code labels.
• The SCANNER.INI file contains configuration information for each type of
scanner device. The SCANNER.INI file must remain on drive D. If
SCANNER.INI is not on drive D, you cannot configure the Scanner Devices
(SS) parameter to any value except "All compatible scanners." Any attempt
to do so will generate an error:
When You Do This
You use IC.EXE to configure the
Scanner Devices parameter.
You scan or type a configuration
command that sets the Scanner
Devices parameter to any other
value.
You load a configuration file (such
as JANUS.INI) that sets the Scanner
Devices parameter to any other
value.
