Abstract: An image reading apparatus has a scan quality parameter extraction part, a scan quality evaluation part and a notification part. The scan quality parameter extraction part extracts scan quality parameters representing the quality of a scanned image from image data based on a scan error detection algorithm. The scan quality evaluation part determines whether a scan error occurs, based on the scan error detection algorithm and the scan quality parameters. Also, the notification part notifies a result determined by the scan quality evaluation part to a user.

Abstract: A system for controlling access to devices using direct connect protocols includes a network of computers, printers, personal digital assistants and servers. Client devices are programmed to embed one or more access codes in job streams (e.g., a word-processing file to be printed) when requesting services from other devices. A method includes a device (e.g., network printer) parsing a job stream received from a client device (e.g., computer) to find one or more embedded access codes, identifying each embedded access code that matches a stored access code, and authorizing one or more device features associated with each identified matching access code.

Abstract: Method for acoustic dampening of photoreceptor and ionographic drums using an acoustic dampening applied to and cured on the interior of a drum. Embodiments provide excellent acoustic dampening of the resonance modes, and thus, substantially eliminates the problematic sounds that are often emitted from the xerographic printing machines.
Abstract: The present disclosure provides a printing device comprising a sheet buffer including a paper path having a plurality of nip pairs for selectively receiving and releasing a plurality of printer sheets. The plurality of nip pairs include a fixed load nip pair, a fixed unload nip pair, and at least another intermediate fixed nip pair therebetween. In a first operation each subsequent sheet of the plurality of sheets is shingled over a previous sheet wherein the plurality of sheets can be stopped in the intermediate nip pair or pairs. Individual sheets of the plurality of sheets can be advanced to the unload nip pair sequentially in a second operation whereupon the individual sheets are successively unloaded as needed in a first in first out order.
Abstract: A method and system receives test requirements and test settings in order to design a test. An identifier is assigned to the test that was designed and the test is stored in a database using the identifier to identify the test. In addition, the test is printed on at least one sheet or form and a wireless read/write device is programmed with the identifier assigned to the test. The wireless read/write device is attached to the sheet on which the test was printed. Thus, the sheet and the wireless read/write device can be provided to a test operator to allow the test operator to wirelessly read the identifier from the wireless read/write device. Then, the test operator can access the test from the database based on the identifier read from the wireless read/write device. The test instructions (comprising the test requirements and test settings) are provided from the database to the operator to perform the test and potentially produce a physical test output.

Abstract: A device processing history storage system in which a device and a terminal are connected through a network, in which the terminal includes: a request portion which transmits to the device a request for device processing or a request for storage of a history of the device processing; a history request portion which requests the device for the history; and a history display portion which displays the history received from the device, and the device includes: a device processing portion which performs the device processing; a history generation portion which generates a history of the device processing performed by the device processing portion; a history storage portion which stores the history generated by the history generation portion; and a history transmission portion which transmits to the terminal the history which is stored in the history storage portion.
Abstract: A system and method processes object oriented image data by initially parsing the object oriented image data into non-neutral image data and neutral image data. A second parser circuit parses the neutral image data into black image data, grey image data, and white image data. A neutral processing circuit processes the black image data, grey image data, and the white image data. The system also classifies object oriented image data to be rendered by an object oriented rendering system. To perform the classification, the object oriented image data to be rendered is received and classified and assigned as one of a plurality of possible first level object types. The process further classifies and assigns, to the object oriented image data to be rendered, one of a plurality of possible second level object types related to the first level object type assigned to the object to be rendered.
