9.2 OPERATION
9.2.1 Airflow
• Air is exhausted from the fusing section, paper exit section, and power supply section of the main body, and inside of the machine. The
clean unit takes the exhausted air into the clean unit via each duct.
• The UFP filter collects the air UFP (Ultrafine Particle) that is exhausted from the main body.
• Air passing through the UFP filter is exhausted out of the machine through the exhaust fans 1/2/3 in the clean unit.
NOTE
▪ The UFP filter does not require a periodic replacement.
