Chapter 2: Troubleshooting Problems
Overview
The NCR 7169 Multifunction Printer is a simple and generally trouble–free printer. The
multi–colored LED lights provide users with visual feedback for error correction. For
some problems, the printer communicates the information to the host computer and
relies on the application to indicate the problem.
This section describes some problems that you may encounter with the printer. You
may be able to fix some of the conditions or problems without calling for the assistance
of a service representative. However, if a problem persists, contact a service
representative. For more information, refer to Contacting a Service Representative on
page75.
