Supply Life Counter Behavior - Xerox 3450B - Phaser B/W Laser Printer Service Manual

Supply Life Counter Behavior

An internal counter tracks copy count information and stores the values in NVRAM.
The Main Board monitors this counter in order to display the near end-of-life and
end-of-use messages.
Consumable (toner/print cartridge) usage is tracked by the CRUM and monitored by
the Main Board in order to display the near end-of-life and end-of-life messages. The
value currently stored (in print cartridge cycles) can be viewed using the Read OPC
Cycle Service Diagnostic. The trigger values are as follows:
■
10K Cartridge: 78,000 = Toner Low, 92,000 = Replace Cartridge
■
5K Cartridge: 39,000 = Toner Low, 46,000 = Replace Cartridge
Life ratings are based on 5% coverage and an average 4 page job length.
