4039-1XX
Scheduled Mechanical Maintenance
The operator panel will display the message “80 Scheduled
Maintenance” at each 200K (100K for 12C) page count interval. It is
necessary to replace the fuser assembly, transfer roller, d-roll, and
lower redrive shaft assembly at this interval to maintain the print
quality and reliability of the printer. These items are available as
individual FRUs. They are also available as a maintenance Kit
through the dealer options ordering channel.
After replacing the kit the maintenance count must be reset to zero
to clear the “80 Scheduled Maintenance” message.
