Question No.2 Why is an ozone filter present in SCX-8128 Series (Mono), and not in CLX-9301 Series (Color)?
Answer Corona charging method is non-contact type which emits ions generated by
Corona-discharging in air to OPC surface. In this process, ozone (ions) is generated in developer unit
area. After charging process, ozone filter collects ozone from developer unit. On the other hand, contact
charging type like roller-charging has no need to implement ozone filter, because there is no ozone produced
in developer unit.
