Ozone filter life detection

• The life counter of the ozone filter controls detection of life of the transfer belt (transport
motor).
• The counter value is recorded in the service EEPROM board of the machine.
• The ozone filter is shipped with the image transfer belt unit.
Controlled item
Transfer belt (transport motor) rotation time
*1: M represents a code that denotes the motor rotation time.
A. Life determination
• If the count of the transfer belt rotation time counter reaches the threshold, the machine
determines that the ozone filter has reached a new state.
