Basic Troubleshooting - NCR 7158 Owner's Manual

Chapter 3: Using the Printer 3-29

Basic Troubleshooting

The 7158 printer is a simple, generally trouble-free printer, but from
time to time minor problems may occur. For example, the power
supply may be disconnected or the thermal printhead may overheat.
The On Line, Paper Status, Error LED on the operator panel may signal
that something is wrong. The light on the front right side of the printer
is used only to indicate when a form is inserted properly. It does not
indicate an error.
For some problems, the printer communicates the information to the
host computer and relies on the application to indicate what the
problem is.
The information on the following pages describes some problems that
you may encounter: problems that you can easily fix, and others that
you will need to contact a service representative for.
You may be able to correct many of the conditions or problems without
calling for service. However, if a problem persists, contact a service
representative. See "Contacting a Service Representative" at the end of
this chapter.
