Chapter 4: Troubleshooting Tips
The PowerLook IIIscanner was designed to provide a hassle-free installation and
operation. However, should you encounter problems with your scanner, correct
them by way of the troubleshooting tips given in this chapter.
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.
1.
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.
2.
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 on-line
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 and IBM 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.
3.
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.
