Chapter 3: Solving Problems
The 7156 printer is a simple, generally trouble-free printer, but from time to time minor
problems may occur. For example, the power supply may be interrupted or the thermal
printhead may overheat.
A red LED on the operator panel signals that something may be 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.

Printer Beeps Twice at Power On
If printer beeps twice during level 0
diagnostics, it indicates that default values
have been loaded into the EEROM. No action
is necessary.
If the printer beeps twice at
every power on, the EEROM has
failed
The PC Board needs to be replaced. Contact a
service representative.

If the power supply is plugged in, but does not
come on, you will need to order a new power
supply.
