Abstract: A supply item has toner for use in an imaging device. A chip has memory storing quanta indicating allowed usage of the supply item over its lifetime and a multiplier correlating the quanta to toner mass. The imaging device requires quanta to conduct imaging operations and loads the quanta and multiplier by way of a certificate stored in the memory. The imaging device retrieves quanta from the chip over time and both devices keep tally. Initialization between the supply item and imaging device includes providing encrypted and unencrypted instances of firmware versions and certificates from the supply item that the imaging device can compare for security. Alternatively, the supply item defines a fuser assembly, imaging unit, intermediate transfer member, or other component installed for use in the imaging device.

Abstract: A method and apparatus for configuring an electronics device. The method includes receiving, by the electronics device, a request for a command to perform a predetermined operation by the electronics device and sending the command in response to receiving the request. The electronics device then receives a signature based upon the command, whereupon the electronics device verifies the signature by the electronics device and, following an affirmative verification, executes the command for performing the predetermined operation. In this way, the electronics device may be reconfigured remotely without knowledge of the particular command for performing the predetermined operation by the electronics device.

Abstract: A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.

Abstract: A method for securely identifying whether an end user owns a particular device from a manufacturer and is a valid participant in a promotion with a partner of the manufacturer. The method allows an end user to verify ownership of a particular device via a computer network and securely obtain promotion related information which enables the end user to participate in a given sales promotion with a retail partner of the manufacturer of the device.

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.

Abstract: An ink tank includes a reservoir body for containing an ink supply. The reservoir body has a top opening. A top cover is attached to the reservoir body to close the top opening. The top cover has an outer surface. The top cover is formed from a molded material. An RFID tag is integrated into the top cover by one of insert molding the RFID tag in the top cover when the top cover is molded or securing the RFID tag in a recessed region of the top cover.

Abstract: A system and method for suppression of air bubble generation in the ink supply and nozzles of an ink-containing printer cartridge when ultrasonic welding is performed on the ink-containing printer cartridge. The printer cartridge has a top end and a bottom end, and the bottom end includes at least one ink outlet for the ink within the printer cartridge. The system includes a mounting fixture having a recess for receiving and holding at least the lower end of the printer cartridge, an ultrasonic welding device for welding an article to the printer cartridge, and a fluid or liquid, such as water, collected in the bottom of the recess in sufficient quantity such that the at least one ink outlet on the bottom end of the printer cartridge is immersed in the fluid or liquid. The welding device is preferably an ultrasonic welding horn that typically welds a lid to the top end of an ink-containing printer cartridge.
