of the firmware at the time of delivery is written on the RADF control PC board and finisher

the other firmware version used and then update with a corresponding suitable version.
• The firmware (master data) is not installed on the hard disk provided as a service part. When
the hard disk is replaced with a new one, check the other firmware version used and then
write a corresponding suitable version.
