• Draws outside air into the inside of the machine to prevent the tempera-
ture of the DC power supply, PH section, and other parts from rising.
• Draws outside air into the inside of the machine to prevent the tempera-
ture of the toner cartridge from rising.
• A white belt may occur on the image because of the lower sensitivity of
the PC drum due to ozone accumulated around the PC drum charge
corona. In order to avoid this trouble, ozone filter removes the ozone
inside the PC drum charge corona to keep the sensitivity of the PC drum.
• Ozone accumulated around PC drum charge corona will be absorbed by
ozone filter and be removed.
• When the paper with toner heated at fusing part exit while still at high
temperature, toner may be transferred to other paper on the exit tray.
In order to avoid this, air is applied to cool the toner and paper.
• When the paper with toner heated at fusing part exit while still at high
temperature, toner may be transferred to other paper on the exit tray.
In order to avoid this, air is applied to cool the toner and paper.
• Draws air from the drum unit and developing unit area to prevent the tem-
perature of the process section and image transfer cleaner section from
rising.
• Blows outside air against the MFP board to prevent the temperature of
the board from rising.
• Blows outside air against the CPU to cool it down, thereby preventing the
temperature of the CPU from rising.
