Abstract
A method for using a security system for replaceable components of a electrostatographic reproducing machine which includes the steps of (1) providing the replaceable component with a memory source having a plurality of addressed floating memory locations; (2) randomly selecting one of the floating memory locations as a security location; and (3) writing a security code in the security location. The security code and the address of the security location in the machine memory device is stored in the machine's memory. Periodically, the code in the floating memory location at the address stored in the machine memory device is compared with the security code in the machine memory device. If the two codes are not the same, then an alert code is written into each of the addressed memory locations. If the two codes are the same, then the machine is placed in a stand by mode ready to make prints.
