10 PSU cooling fan
Mechanism
By installing the duct corresponding to each fan, the air flow is efficiently controlled to a cooling target.
Moreover, improvement in quietness and energy-saving efficiency is achieved by performing stepwise
operation of the fan according to the imaging temperature.
Cooling of PSU
Air taken in by the PSU cooling fan is guided near the cooling target by the duct, and is efficiently
cooled.
Cooling of Toner Supply Parts
Air taken in with the toner supply cooling fan is guided to circulate around the toner bottle, and is
discharged from the side of the delivery tray to outside the machine. It is aimed to achieve heat
insulation from the stack of paper to the toner bottle by reducing the melting point of the toner.
Cooling of PCDU parts
By discharging air taken in from the development intake fan at the front, from the ozone exhaust fan at
the rear, a uniform air flow is attained and efficient cooling is realized. Discharge of ozone and
scattering of toner are prevented by installing an ozone filter and a dust filter in front of the ozone
exhaust fan.
Cooling of Fusing Parts
Air taken in from the paper discharge cooling fan at the front is discharged from the fusing heat
discharge fan at the rear to outside the machine. By cooling the paper immediately after fusing, not only
cooling of the fusing exit sensor but also reduction of stored heat of the stacked paper and reduction of
curl are realized. This also serves to prevent condensation on the paper discharge guide sheet. As a
measure against odor, a deodorization filter is installed downstream from the fusing exhaust fan.
Cooling in Controller Box
Air is circulated by the controller box cooling fan installed in the controller box, preventing temperature
rise in the controller box.
