The operator panel displays the message 80 Scheduled Maintenance at each 300K page count interval. It is necessary to replace the fuser assembly, transfer roller, charge roll, and pick tires at this interval to maintain the print quality and reliability of the printer. After replacing the kit, the maintenance count must be reset to zero to clear the “80 Scheduled Maintenance” message.Compatible Printers: Lexmark Optra T 654 N, Lexmark Optra T 652 DN, Lexmark T 656, Lexmark T 654, Lexmark Optra T 654 DTN, Lexmark Optra T 656, Lexmark Optra T 650 N, Lexmark Optra T 652 DTN, Lexmark Optra T 654 DN, Lexmark Optra T 650 DTN, Lexmark T 650, Lexmark Optra T 652 N, Lexmark T 652, Lexmark T 652 DN, Lexmark T 650 DN, Lexmark T 654 DTN, Lexmark T 652 DTN, Lexmark Optra T 650 DN, Lexmark Optra T 656 DNE, Lexmark T 650 N, Lexmark T 650 DTN, Lexmark T 656 DNE, Lexmark T 652 N, Lexmark T 654…
