Problems Scanning Bar Code Labels
If you cannot scan bar code labels or you are having problems with the scanner, check
these possible problems.
Problem Solution
The terminal is turned off. Make sure the terminal is turned on. Press to turn on the terminal.
You cannot see a red beam of light from the
scanner when you press the scan button and
aim the scanner at a bar code label.
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.” Try changing the
scanning angle.
Warning
Do not look directly into the window area or at a reflection of
the laser beam while the laser is scanning. Long-term exposure
to the laser beam can damage your vision.
Avertissement
Ne regardez pas directement la réflexion d’un rayon laser ou
dans la fenêtre du laser lorsque celui-ci est en opération. Si
vous regardez trop longtemps un rayon laser, cela peut
endommager votre vue.
You have an input device attached to the
terminal and it cannot read any bar code
labels.
You may not be using an input device that is supported by the 243X.
Make sure you are using one of the supported input devices listed in
Appendix A, “Specifications.”
Your 243X may not be configured for the input device connected to it.
You must configure the Scanner Selection command and select the
input device that is connected to the terminal. For help, see “Scanner
Selection” in Chapter 6, “Configuration Command Reference,” in the
2400 Family system manual.
You try to scan a bar code label with an input
device and the integrated scanner on the
terminal turns on.
Your 243X may not be configured for the input device connected to it.
You must configure the Scanner Selection command and select the
input device that is connected to the terminal. If this command is not
defined for the appropriate input device, the scanner trigger on the
input device may activate the integrated scanner on the terminal. For
help, see “Scanner Selection” in Chapter 6, “Configuration Command
Reference,” in the 2400 Family system manual.
The input device connected to the terminal
does not appear to work well or read bar code
labels very quickly.
Make sure that the Scanner Selection command is set to the specific
tethered scanner you have attached. For help, see “Scanner Selection”
in Chapter 6, “Configuration Command Reference,” in the 2400 Family
system manual.
Check the bar code symbologies you have enabled on the terminal.
Enable only the symbologies that you are using.
