Abstract: A method of generating an authentication code for a consumable in an imaging device, includes the steps of: an identification number assigned to the consumable; processing an indemnification number assigned to the consumable using a first algorithm to generate a preliminary number different from the identification number; and compressing the preliminary number using a compression algorithm that utilizes the identification number to generate the authentication code.

Abstract: An image forming device including an electronic filing cabinet is provided. The electronic filing cabinet stores documents output from the image forming device or read into the image forming device. The electronic filing cabinet may include an optical character recognition unit, an indexing engine and a storage device. The optical character recognition unit scans or otherwise inspects the documents and generates timestamps for the documents. The scanned information is provided to the indexing engine. The indexing engine classifies and indexes the documents according to a first predefined set of rules. Thereafter, the indexed documents are stored in the storage device. A human machine interface is provided for updating the first predefined set of rules. Previously stored documents may also be retrieved through the human machine interface.
