When Something Goes Wrong
The EFP9800 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 paper may jam.
For some problems, the printer communicates the information to the host
computer and relies on the application to indicate the problem.
You’ll be able to fix most problems easily. For some problems, you will need to
contact a Unisys-authorized service representative. Any time a problem persists,
contact a service representative.
Following is a list of problems you may encounter and the page on which they
