Base Sensor Test

This test determines whether or not the sensors located inside the
printer are working correctly.
Once this screen is displayed, you can open the doors and manually
actuate each of the sensors. When the sensor is closed, CL is dis-
played. When the sensor is open, OP is displayed. If the wrong mes-
sage is displayed, then the sensor is malfunctioning. See "Switches
and Sensors" on page 4-7.
The following sensors can be checked:
Timing Roll sensor
Fuser sensor
Exit sensor
Transparency Detect sensor
Fuser Detect sensor
Waste Toner Bottle Detect sensor
T/C Rack Detect Sensor
Coating Roll Detect sensor
Intermediate Transfer Belt sensor.
As the sensor test runs, the panel displays whether the sensor is
open (OP) or closed (CL). You may toggle each sensor by hand to
determine that the sensor is reliably switching between open and
close.
To exit the sensor test, press Return or Stop.
