Machine CRU Strategy
Machine LCB is designed to interface with a CRUM and Billing Counter on all configurations.
The CRUM can be used to provide a "hard stop" capability for markets requiring this feature.
The primary uses of the CRUM are to ensure that the CRU being used is correct for the market
& service/warranty agreements, store the number of copies made on the CRU, and enforce the
end-of-life point. The primary uses of the Counter are to indentify the machine's market loca
-
tion, electronically store the machine's serial number, and store the number of copies made on
the machine.
Consumable Replacement Intervals (TBD)
This specification is applied when the machine is operated under the following conditions:
– Paper: A4 LEF
– Paper Tray: Tray 1
– Copy Mode (not Print Mode)
