Chapter 5: Troubleshooting Tips
The PowerLook 1120 scanner was designed to provide trouble-free installation and operation.
However, should you encounter problems with your scanner, try the following troubleshooting tips.
For persistent problems with your computer, consult your dealer or approved service personnel.
General Approach
In most cases, a problem does not call for the service of a qualified technician. The solution may be
very simple, such as correcting cabling connections and the like. The solution of a problem normally
lies at the source of the problem. Therefore, it is important that you ascertain the cause of the failure or
malfunction. Below is a general troubleshooting approach.

Check the connections and installation. Ensure that there are no loose connections. Ensure that
the settings on the scanner and/or the interface card are correct.
Check the error messages appearing on the screen. Does the message point to a hardware problem
or software problem?
If the problem is software-related, refer to the software reference manuals or online help. Most
software manuals include a troubleshooting chapter.
If the problem is hardware-related, verify that the cause is from your computer or scanner or in
some cases, your network. If it is due to your computer malfunctioning, then consult your
computer’s reference manuals or a computer service technician.
Note:
Macintosh computers and compatibles display error messages that normally tell you the cause
of the problem and in some cases tell you what to check or do to solve the problem.
If the error message points to a problem with your scanner system, run the scanner self-test.
Turn the power of your scanner on. At power-on, your scanner automatically runs the scanner
self-test which can detect most of the problems with your scanner. Observe the behavior of the
LED indicators. Record all your observations.
If the above does not help, please contact our Technical Support Group at
or call (214) 739-1915 (M-F 9AM to 5PM Central Time).
To facilitate servicing, supply your dealer with the following information:
•
Scanner model
•
Operating System (Windows version or Mac OS number)
•
A detailed description of the error
•
If you are on a Mac system, the version numbers for the FireWire extensions.
•
The text from any Error codes or messages seen.
•
Description of what you were doing at the time the malfunction or failure occurred.
•
Description of what you did to attempt to solve the problem.
•
Other observations that may aid the technician in identifying the problem and the solution.
