Fusing Pressure Roller • Applies pressure to the toner to fuse it into the media
• Toner is fused by the Fusing Pressure Roller and Fus-
ing Belt
[8]
Fusing Pressure Roller Thermostat
(TS2) • Detects an abnormally high temperature of the Fusing
Pressure Roller
• Non-contact type
[9]
Fusing Entrance Guide Plate • Guides the media between the Heating Roller and
Fusing Pressure Roller
[10]
Fusing Motor (M4) • Drives the Fusing Pressure Roller and Paper Exit
Roller
[11]
Heating Roller • Heated to a required temperature by the heater lamp
provided inside this roller
• Supplies the Fusing Belt with heat
[12]
Heating Roller Heater Lamp (H1) • Heats the Heating Roller
• Heater lamp: 700 W
[13]
Heating Roller Thermistor (TH1) • Controls the temperature of the Heating Roller
• Type in contact with the roller
[14]
Heating Roller Thermostat (TS1) • Detects an abnormally high temperature of the Heat-
ing Roller
• Type in contact with the roller
[15]
Fusing Belt • Applies heat to the toner to fuse it into the media
• Toner is fused by the Fusing Pressure Roller and Fus-
ing Belt
[16]
Fusing Pad • Presses the Fusing Belt against the Fusing Pressure
Roller
[17]
Paper Size Sensor (PC23) • Detects the size of the media conveyed from the Fus-
ing Pressure Roller and Fusing Belt
[18]
Paper Exit Roller • Feeds the media conveyed from the Fusing Pressure
Roller and Fusing Belt out into the Exit Tray
[19]
Paper Holding Plate • Guides the media fed out of the machine into the Exit
Tray
• Prevents the trailing edge of the media from failing to
clear the Exit Roller
• It also serves as the actuator of the Paper Full Sensor
(magicolor 5450 only)
[20]
Paper Full Sensor (PC20) • Detects load capacity full of the media fed to the print
tray (magicolor 5450 only)
