Solving Problems
The 7193 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 printhead may overheat for some reason.
Lights on the operator panel will signal that something may not be operating
properly: one green light and one red light may either flash or glow continuously
as described in the following table and on the following pages.
