A particle-containment shield is provided. The particles-containment shield includes a containment structure that defines an air inlet to receive air heated by a projection lamp from the outlet of the projection-lamp module and defines an air outlet to vent air heated by the projection lamp away from the projection lamp. The containment structure is sealed intermediate the air inlet and the air outlet such that air heated by the projection lamp that enters through the air inlet exits the containment structure through the air outlet. The containment structure defines a length, a width, and a height of the particle-containment shield. The particle-containment shield includes one or more deflection members is arranged in the containment structure to collectively block all straight line paths from the air inlet to the air outlet so as to inhibit projection lamp particles from exiting the air outlet upon projection lamp rupture.

Document processing devices and account manager systems are presented which verify validity of pairings of installed consumables and document processing devices for permissive enablement of document processing functionality based on validity of the pairings.

Methods and system for consumable validity verification in prepaid document processing devices

According to aspects of the embodiments, there is provided systems, computer readable media, and methods to authenticate a customer replaceable unit (CRU) in a printer system by comparing a validation code in the CRU with a printer generated validation code. The Validation Code is a string of numbers and/or characters that can be referred to as a value. The validation code will be comprised of a value string including programmed characters representing a combination of all or portions of a market program designator or code, consumable identification (ID) information and a randomly generated value, which may be hidden from view. The code is independently established by the printing system or device using the same algorithm and information and validates the resulting Code when they match. The printing system or device must confirm the Validation Code and ID applicability of the consumable to deem it appropriate for use.

Multiple market consumable ID differentiation and validation system

According to aspects of the embodiments, there is provided methods and systems for authenticating an imaging device consumer replaceable unit (CRU) used in products such as a printing system with appropriate programming such that they are able to positively recognize and accommodate authorized consumables. A microcontroller or processing chip is integrated with the CRU and capable of generating a Validation Code. A code key will be comprised of a value string including programmed characters representing a combination of all or portions of a market program designator or code, consumable identification (ID) information and a randomly generated value, which may be hidden from view. The resulting string key is a basis for an algorithm created Validation Code. This code is generated by the consumable processor and readable by a printing system or device the CRU is inserted into. The code is independently established by the printing system or device using the same algorithm and information and validates the resulting Code when they match. The printing system or device must confirm the Validation Code and ID applicability of the consumable to deem it appropriate for use.
