The operator panel displays the message “80 Scheduled Maintenance” at each 250K page count interval. It is necessary to replace the fuser assembly, transfer roller, compensator pick-rolls and charge roll at this interval to maintain the print quality and reliability of the printer. The parts are available as a maintenance kit with the following part numbers:

99A0290 - 100V/750W 2450

99A0500 - 115V/750W 2420/2450/2455

99A0823 - 115V/750W 3455

After replacing the kit, the maintenance count must be reset to zero to clear the “80 Scheduled Maintenance” message. Refer to “Maintenance Page Count (2420/2450/2455/3455)” on page 3-20 .
