An important key to reliable operation of your Star LaserPrinter 4111 is
knowing how to respond when trouble occurs. Some problem conditions can
be handled on the spot by the printer operator. Others require servicing by
trained personnel. This chapter will explain when to do what. It will also help
you deal with the paper jamming and other operational problems.
8.1 ERROR MESSAGES DISPLAYED ON THE
SCREEN
The control panel screen may display a variety of messages during the course
of operation of the Star LaserPrinter 4111. You are already familiar with the
display sequence during power-up, and when programming the printer.
Some messages provide information about the paper supply in the cassette
or the condition of the EP-L cartridge. Others have to do with fonts or
emulations.
Another way of considering errors is that some of them result from failures
in hardware or software. Other errors are functional, meaning that either the
printer operator or the host computer has commanded the controller to
perform an operation that is beyond its designed capabilities.
If the printer malfunctions for some reason, warning messages will appear
on the screen, recommending what action you should take. The most serious
are messages that tell you to call for repair service. Some messages concern
less serious conditions that can be handled by the printer operator. Informa-
tion messages relate a communication problem with the host computer, but
do not affect the printer’s operation. These messages are summarized here.
