3. IF YOU REPLACE THE LOW VOLTAGE POWER SUPPLY PCB ASSY
3.1 Reset of Irregular Power Supply Detection Counter
The irregular power supply detection counter is counted up when the printer detects irregular
power supply. If the counter reaches to the limit, the printer shows the service error to
replace the low voltage power supply PCB because it might be damaged by recursive
irregular power supply.
In this case, if the same power supply is used, the same error may occur even when the low
voltage power supply PCB ASSY is replaced. Ask the user to review the installation
environment.
(1) Open the front cover, and turn the power supply of the printer on while pressing down
the [Go] button. Make sure that the Toner/Drum/Error LED light up.
(2) Release the [Go] button, and then make sure that all LEDs light off.
(3) Press the [Go] button for over 2 seconds, and the Error LED light up. And then the
printer goes into the PIT3 mode.
(4) Connect the printer to PC with USB cable.
(5) Double-click the "FILEDG32.EXE" on PC to start. The following screen appears.
Select the "Brother Maintenance USB Printer".
(6) Drag the SQWAVE.PJL and drop it onto the Brother Maintenance USB Printer icon.
