■ Safety
For user and service technician's safety, the printer has a function to interrupt 24V power supply to the fixing unit and the high-
voltage power supply unit.
The door switch is turned off and 24V stops under the following condition:
• If the cartridge door is opened (SW301 is turned off)
The printer has the power switch on the DC line so the AC power flows even the power switch is turned off. Be sure to unplug
the power cord before disassembling the printer.
■ Low-voltage power supply unit failure detection
The DC controller determines a low-voltage power supply unit failure, stops +24V1 output and notifies E808 to the Main controller
when it encounters the following condition:
• +24V is higher than a specified voltage
