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.
