Display Sensors
The Display Sensors menu item actively monitors the state of all sensors and
switches in the imagesetter. With this menu, the user activates or deactivates a sen-
sor and monitors the state of the sensor on the display (e.g., moving a jam wheel
causes the state of the sensor to display on and then off as the wheel moves
through the sensor). This utility aids in troubleshooting sensor problems in the sys-
tem. Below is a typical Engine (imagesetter) Sensor Display screen.
