Control Conditions
• It exhausts the accumulated heat inside the unit in order to prevent
temperature from increasing at DC power supply part.
• The Ozone Filter traps to remove odor stagnant inside the machine.
• Heat accumulated inside the machine is discharged out to prevent
the interior temperature from rising inordinately.
• The Ozone Filter provided in the IU traps to remove ozone stagnant
in areas near the PC Drum Charge Corona.
• Heat stagnant in the Fusing Unit is discharged out of the machine.
• Heat accumulated inside the machine is discharged out to prevent
the temperature of the Fusing Unit from rising inordinately.
• The Toner Filter traps toner particles that have scattered during
developing.
