Abstract
A method stores serial numbers within memories of customer replaceable units that are used within printing devices. When one or more of the customer replaceable units are replaced, the method causes the printing devices to output to a computer the serial numbers of the customer replaceable units that are replaced. The method then analyzes the serial numbers using the computer to determine which specific customer replaceable unit was used within a specific printing device.
