Operator Panel Test

This test activates each LED in sequence and cycles all pels of the 
LCD display. It also allows the servicer to test each button.

1.  Press Setup.

2.  Press 2104 to activate the Service Functions menu.

3.  Press the right arrow to move the pointer to Testing, then press 

OK.

4.  Select PNL.

5.  Press any button (except Stop) to start the button test. Follow the 

instructions on the display to press and test each button.

6.  Press Stop at any time to end the test. Press Stop several times 

to exit the menus.

Reset Button

This recessed button on the operator panel is covered with a shield 
and must be pressed with a small tool or straightened paper clip.

The Reset button does a hardware reset of the fax board and opera-
tor panel. Pressing Reset does not erase stored faxes or the con-
tents of the phone book. The Reset button does not reset the printer 
board; unplugging the machine resets the printer board.

Print Engine Test

Use the Print Engine test for testing the printer board and inkjet 
printer engine independent of the other machine subsystems. This 
test can be run with the fax, LCU, or operator panel boards discon-
nected or defective. 

1.  Unplug the machine. 

2.  Remove the right cover and locate printer board header J7. 

3.  Short all four pins together with a screwdriver and plug the 

machine in.

The test print will run continuously until the machine is unplugged. 
The pins do not need to stay shorted after the test starts.
