Customer Replaceable Unit Monitor

And Wireless communication systems to provide improved document services


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 and associated enabled services, including:
  • Elimination of warranty returns for counterfeit materials
  • Early warning of the need to change the part
  • Remaining life indication
  • Batch information
  • Warranty protection
  • Wireless solutions for document devices, and document services

Examples of Mobile Services Across Wireless Networks

With early priority dates from 1998, this segment of the CRUM portfolio provides improvements to devices and services operable using wireless networks, including:
  • A method for determining the proximity of mobile devices in a wireless network. This method provides solutions for the stability and orientation problems associated with WiFi triangulation by use of inexpensive sensors in the mobile device (e.g., for motion detection and signal calibration). Also, a proximity sensing method is provided that allows two or more devices to determine proximity in a peer-to-peer fashion, across a wireless network, by exchanging network characteristics observed in real time. U.S. 7042391
  • An e-mail method that allows users to selectively send emails with attachments to a primary recipient while concurrently directing a copy (“CC”), without attachments, to additional recipients, thus decreasing the amount of storage space that an e-mail consumes on an e-mail server while increasing the speed and efficiency of an e-mail provider. U.S. 6628306
  • A system for performing document services using mobile computing devices whereby devices of the system receive document references transmitted over integrated wireless and wire-based communication services. Each mobile computing device holds a user's personal collection of document references that can be received, transmitted, and stored. A user interface at the mobile computing devices provide a user with fast and easy access to proximate document services. U.S. 6421716
  • A method for wirelessly updating document devices, such as printers and copiers, which allows the devices’ option features and capabilities to be altered. Options include: device/machine speed, machine stand alone mode, or network connected mode, scanning enabled; scan to email; scan to Internet Fax; immediate job overwrite, etc. System option updates and reconfiguration are provided without the need for a field service call. U.S. 7197633; U.S. 7321966; U.S. 7334261
  • An apparatus for wireless data communication with multiple memory devices within a document device that reduces the need for separate sets of hardware to communicate with each of the memory devices, and can enable communication between different modules of a document device. An interface antenna may be provided for increasing the distance over which a tag (e.g., RFID tag) can communicate with a reader (e.g., RFID reader) without increasing the size of the antenna on the tag. U.S. 7307531; U.S. 7504951
