Function

A. Fusing fan motor
• Fusing fan motor discharges heat generated from the interior parts (including the DC
power supply, fusing unit, toner cartridges/K, and motor drives) out of the main body to
prevent the interior temperature from rising inordinately.
• Air passageway is formed on top of the DC power supply, in the duct inside the toner car-
tridge rail, and below the print head housing. No air flows through areas around the toner
cartridges. This effectively prevents toner from scattering.
B. DC power supply fan motor
• Discharges heat generated from the interior parts (including the DC power supply, inter-
mediate transfer belt section, toner cartridges/C, M, Y, and motor drives) from the main
body to prevent the interior temperature from rising inordinately.
C. Ozone fan motor
• Discharges heat generated from the print head from the main body to prevent the print
head temperature from becoming inordinately high.
• Removes ozone produced from the toner cartridges and charging section.
• Air passageway is formed on top of the DC power supply, in the duct inside the toner car-
tridge rail, and below the print head housing. No air flows through areas around the toner
cartridges. This effectively prevents toner from scattering.
