Customer Replaceable Unit Monitor

Xerox's Customer Replaceable Unit Monitor technology defines a process by which the state or status of consumable subsystems can be monitored to enhance the efficiency or productivity of the machine on which it is installed. For example, consider the toner supply subsystem of a xerographic copier that monitors the amount of toner remaining. This CRUM can provide feedback to the copier as to the number of copies that can be made before a toner cartridge replacement is required – if a user selects a copy quantity in excess of what can be printed, the user can be alerted so that appropriate action may be taken. This technology is applicable to all machine subsystems which contain consumables. Our over 100 issued US patents in CRUM technology and rich knowhow cover the areas of hardware, software, and applications, including recent breakthrough of wireless communication and authentication.

There are compelling business reasons and customer value added benefits of adding CRUMs, including:

Elimination of warranty returns for counterfeit materials
Early warning of the need to change the part
Remaining life indication
Batch information
Warranty protection
