XEROGRAPHIC COPY CARTRIDGE LIFE OPTIMIZATION(Cont'd)

Many electrophotographic printing and copying machines function with operator replaceable cartridges for toner and or developer materials. These supplies are also known as customer replaceable units (CRUs).

A control system mechanism is proposed to provide printing and copying machines with CRUs that additionally possess a customer prompt mechanism that allows a user/operator to determine approximately how many copies may be produced before marking supplies are exhausted and require replacement. The mechanism counts copies already prepared from a cartridge in use and may show, for example, via a panel display, the number of additional copies that may be prepared from remaining on-board developer and toner materials. A mechanical copy sheet counter is connected to a user interface to alert a user about the status of a CRU that is in use. A microprocessor conveys status information to the user interface.

A customer prompt mechanism optimizes useful run time available for users and notifies the operator of anticipated material demands for continued successful mach...
