4 Check the function of the sensors and switches by manually actuating with your finger or a screw
driver. If the sensor or switch is functioning correctly, the number at the position on the bottom
line of the LCD increments by one each time you actuate the sensor or switch. If the number
does not increment, the sensor or switch may be faulty.
5 If you wish to exit this test and enter another test, press the ITEM UP (2) key until the LCD
displays SENSOR INPUT TEST, then press the MENU UP (1) or MENU DOWN (5) key.
6 To exit this test and return to normal operation, switch OFF the printer power then switch it ON.
WARNING! Never run the SENSOR INPUT TEST with the Front Cover open because the laser
light is emitted if you press on the interlock switch and LD switch simultaneously by
actuating or cheating. Disconnect connector P/J 118 on the CRU Sensor PWB or
connector P/J 12 on the Print Engine Controller PWB before executing SENSOR
INPUT TEST when you must perform the input test with the Front Cover open.
