Abstract: An image forming device includes: an image carrier that carries an image; a development unit that develops, with toners, a latent image written on the image carrier; an intermediate transfer member to which the toner images formed on the image carrier by the development unit are primarily transferred; and a fixing unit that fixes, to paper, the toner images secondarily transferred from the intermediate transfer member. The image carrier and the intermediate transfer member are unitized to configure an image forming unit, and the image forming unit is disposed in a space sandwiched between the development unit and the fixing unit. The image forming unit further includes a loading/unloading allowing unit that allows the loading/unloading of the image forming unit.

Abstract: Text, images, and/or graphics of electronic documents should be organized and laid out in a two-dimensional format for presentation to the viewer. The best such layout depends upon the content present, the creator's intent, the output device, and the viewer's interests. To analyze the qualitative nature of the layout in quantifiable terms, the electronic document is measure using various quantifiable factors; such as, balance, uniformity, white space management, alignment, consistency, legibility, etc.; that impact a qualitative nature of a document. Such quantifiable factors are then used to quantize the aesthetics, ease of use, eye-catching ability, interest, communicability, comfort, and convenience of the document.

Abstract: A method for encoding and decoding frames by generating a key bitstream such that the key bitstream never has to be stored is disclosed. The method consists of a key generation algorithm using a threshold matrix to generate a key that is very similar to original bitmap data. The key generation algorithm searches the bitmap for equivalent image sets that produce the same bitmaps. These equivalent image sets consist of runlength of constant image values and the actual runlength. Additionally, the image values for the runlengths are never explicitly encoded. During compression a preprocess algorithm XORs the MINIMAL number of hints required to find a equivalent image value for the runlength. The postprocess algorithm is capable of distinguishing if a single bit represents an image value adjustment hint or if it represents the end of a runlength.

Abstract: Sheet registration with improved sheet deskewing of print media sheets may be provided with an intermediately transversely pivotal baffle member overlying and engaging at least part of a buckled sheet being edge registered so that the effective buckle chamber size and sheet path length on one side of the sheet is automatically different from the other side of the sheet with said pivoting of said pivotal baffle member, to assist in the deskewing of the sheet as it is being partially buckled by the sheet registration system. The direction and amount of baffle pivoting may be self-pivoted by the extent of transverse buckle difference, or positively driven in response to a detected sheet skew.

Abstract: A system and method of evaluating the required operating capacities for each production function for each consolidation configuration of distributed print shops in an enterprise so that the most appropriate print shop consolidation options can be selected. Operating capacities of each production function for processing print jobs at each shop is initially determined on the basis that the print jobs can originate and be processed at the same print shop. The operating capacities are modified to take into account scenarios in which the print jobs can originate at each print shop and can be transported to each other print shop for processing. The determined maximum operating capacities at each shop can be mapped out for each possible configuration of consolidating a selected number of print shops into a selected number of consolidated shops.
