13. THV(+)
TRIGGER.
ALL HV
All high voltage output by each HV terminal and LSU and the fan is in operation. In this mode, electronic
resistance of transfer roller and high voltage is detected. If no toner cartridge in the printer, output of THV is
+199V ~ + 2100V.
14. PTL Test
Indicates the PTL LED.
15.
Fan Test
Indicates the function of the fan.
4-1-4 Self Test Button
If the Self-Test button pressed, vertical lines are printed.
Turn the power on while pressing this button, '89' shows in the DCU and the printer is warming up. After warming-up the
printer is in READY Mode, and '88' shows in the DCU. In this mode, without any detection, the printer begins
printing(trial printing and data from the PC). It is convenient to use this mode when the engine malfunction is detected in
the control board.
