Main Fan
The Main Fan removes heat from the printer to prevent overheating.
Electrically Erasable Programmable Read-Only Memory (EEPROM) Board
The EEPROM Board stores the printer unique information. Information on the
EEPROM Board is also stored on the Machine Control Unit (MCU) Board.
Humidity /Temperature Sensor
The Humidity/Temperature Sensor reads the humidity and temperature within
the printer.
Interlock Switch
The Interlock Switch is a switch that cuts the +24 VDC power supply to the
HVPS or Motor upon the opening of the Front Cover.
Low-Voltage Power Supply (LVPS)
Two types of LVPS are available: 100/120V and 230V. The LVPS supplies AC
power from the power source to the Fuser Heater; the LVPS also generates
and supplies stable low-voltage DC power used for the logic circuit. The LVPS
contains a control circuit for the heater of the Fuser, in addition to the power
circuit.
