Chapter 4: Troubleshooting
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 (labeled On Line—remote models only) and one red light (labeled Paper
Feed—all models) may either flash or glow continuously. See “Level 2 Diagnostics” in the
“Diagnostics” chapter for definitions of the operator panel lights.
