End-of-Forms Sensor Test
This test checks the end-of-forms sensor on the system board.
Check the end-of-forms sensor by either activating the end-of-forms
flag or by placing a piece of paper in the manual feed slot. The
power light goes on and off as you move the flag past the sensor. If
the test fails, replace the system board.
To run the test:
1. Turn the machine off and move the two pin jumper on connector
J13 to the pin position shown below.
2. Turn the machine on to start the test. Turn power off or unplug
the printer to stop the test.
3. Return the jumper to its original pin position after completing the
test.
