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.
