Diagnosing a Problem
Troubleshooting scanner problems is best handled in two easy
steps: first diagnose the problem, then apply likely solutions
until the problem is fixed. The information that you need to
diagnose the most common problems is provided by the
scanner's indicators. In addition, you can determine whether a
problem lies with the scanner itself or with the computer by
testing the operation of the scanner.
In "Problems and Solutions" later in this chapter you can
find the causes and solutions to specific scanner problems. Use
the information presented in this chapter to pinpoint the source
of your problem, then apply the recommended solutions until
the problem is solved.
Error indicators
You can identify many common scanner problems with the
indicator lights on the front of the scanner. If your scanner
stops working and the lights are on or flashing, use the
following table of light patterns to diagnose the problem,
then follow the recommended corrective measures.
