Scheduled Maintenance (2420/2450/2455/3455)
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
99A0503 - 220V/750W 2420/2450/2455
99A0823 - 115V/750W 3455
99A0824 - 220V/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 .
