Scheduled Mechanical Maintenance
On some models the operator panel will display the message “80
Scheduled Maintenance” at each 200K page count interval. It is nec-
essary 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.
