Abstract: A computer-implemented system and method for processing a markup language document and its change history are provided. The method includes receiving first and second versions of the same target document into computer memory. One of the first and second versions of the target document is encapsulated within an encapsulating document. A change history corresponding to a difference between the first version and the second version of the target document is encoded. The change history is encapsulated within the encapsulating document. The encapsulated document can then be output. As each new version of the target document is created, the encapsulating document can be modified to reflect the changes, enabling prior versions of the target document which have been encapsulated to be extracted at any time.

Abstract: Methods and systems of ejecting ink drops from an inkjet printer are disclosed. The methods and systems can include a printhead with one or more stepped nozzles each with an associated entrance diameter and exit diameter. Ink can be received into the printhead and formed into ink drops in the stepped nozzles. The ink drops can each have an associated drop mass and drop speed. The stepped nozzles can be provided such that the exit diameter can independently dictate the drop mass and the entrance diameter can independently dictate the drop speed. As such, the complexity of jet design optimization is reduced.

Abstract: This is a paper web transporting component that is useful in a duplexing system that uses a paper web to be imaged. The unit has an IOWA roller (backup roll) with an image sensor above it and a cleaning web structure below it. Since excess toner or ink in duplexing systems can adhere to the transport roll, the sensor will pick up these impurities when scanning the surface of the paper web. Therefore, these impurities must be removed from the transport roll or scanning for proper image registration will be adversely affected. The movement of the paper web causes the transport roll to rotate so that the sensor can scan the entire surface of the transport roll.

Abstract: A feeding device includes a body having a sheet placement surface on which a sheet that is to be fed is placed; a cover rotatably provided at the body and supporting a back edge portion in a feeding direction of the sheet placed on the sheet placement surface when the cover is open; a moving member provided at the sheet placement surface so as to be movable in a direction parallel to the feeding direction; a linking member extending in a movement direction of the moving member from the moving member, one end portion thereof being rotatably linked to the moving member using a rotary shaft that is parallel to a rotary shaft of the cover; and a sheet back-edge regulating member provided at the linking member so as to be movable in the movement direction, and regulating a back edge in the feeding direction of the sheet.

Abstract: The present specification discloses methods and systems to enable a peripheral device, which otherwise lacks intrinsic networking capabilities, to be accessible over a network once attached to a local multi-function device, such as computers, laptops, printers, copiers, or other computing devices. An enabling application executing on the multi-function device includes a first layer that communicates with the local peripheral device using a driver specific to the peripheral device, a second layer that abstracts a subset of functions from the first layer and exposes the subset of functions to a third layer, and the third layer which communicates over the network with a client and provides the client access to the subset of functions through standardized calls.

Abstract: An ink level control system includes a first dividing wall that divides a reservoir of a printhead into a first chamber and a second chamber. The first and the second chambers are each connected to the ink passages of the inkjet stack by an ink port. The first dividing wall includes an opening that connects the first chamber and the second chamber to enable ink to pass therebetween. The opening is located a predetermined distance above the bottom surface of the reservoir. An ink diverter is associated with the inlet opening that directs ink received through the inlet opening to one of the first and the second chambers in response to the reservoir being tilted in a first direction, and directs ink to the other of the first and the second chambers in response to the reservoir being tilted in a second direction.

Abstract: A method and apparatus receive a user login and first menu selections through a graphic user interface of a multi-function printing device. The method processes one or more first sheets through a document handler of the multi-function printing device by following the first menu selections. Once finished processing the first sheet (or set of sheets) through the document handler, the method can then receive different (second) menu selections from the user. Then, the method processes one or more second sheets through the document handler by following the second menu selections. In order to provide greater ease of use, the methods herein present the user with an option to revert back to any of the previous menu selections (e.g., the first menu selections) through the graphic user interface. If the user chooses to revert to the first menu selections, the methods herein can process one or more third sheets through the document handler of the multi-function printing device by following the first menu selections.

Abstract: What is disclosed is a novel system and method for determining whether a pixel resides along a two-color edge in a halftoned bi-level bitmap. In one embodiment, a bitmap having a plurality of colored pixels is received. For each pixel in the bitmap, a window of size n×m is defined centered on the current pixel. The window is partitioned into a plurality of regions with each region having an orientation direction with each orientation direction having an associated numeric value. A number of pixels are counted for each of the first and second colors in each of the associated orientation directions. A determination is made as to the respective orientation direction having the maximum and minimum pixel counts for each of the first and second colors. Thereafter, a determination is made whether the pixel resides along a two color edge based upon the max/min counts and each associated orientation direction.
