Pressure belt
The pressure belt is used to apply pressure to the media surface for fusing. Pressure is applied to the media
between the pressure belt and heat roll, pressing the melted toner against the media.
Heater lamp
The heater lamp is a quartz glass tube containing a heater coil. A terminal is mounted to the end of the heater
rod via a harness. Two heater lamps are used: the main heater lamp to heat the entire heat roll, and the sub
heater lamp to heat the central portion of the heat roll.
Thermostat
If the heat roll temperature exceeds the preset temperature, the thermostat cuts off the circuits of the main
heater lamp and sub heater lamp.
Front thermistor
The front thermistor monitors the surface temperature of the media-feed portion of the heat roll to control on/off
of the main heater lamp and sub heater lamp.
Rear thermistor
The rear thermistor monitors the surface temperature at the rear side of the heat roll to switch the heater lamp to
on.
Fuser exit sensor
The fuser exit sensor detects the arrival of media at the detection point in the exit area of the fuser, and also
detects the ejection of media from this point.
Exit
The standard media exit ejects printed media from the printer to the standard bin 1.
