Abstract: A capability is provided to reduce misregistration effects, and/or color-to-color registration errors, in output multi-color images based on velocity and position deviations and/or disturbances in transfer subsystems in image forming devices. A capability is provided to automatically compensate for torque disturbances caused by a photoreceptor belt seam crossing a mechanical device in a photoreceptor belt-based transfer subsystem in an image forming device. A learning algorithm, based on a mathematical model of transfer subsystem mechanical operational dynamics by which a series of performance curves could be generated, is employed to facilitate prediction of a torque disturbance profile in a mechanical motor driven transfer subsystem in an image forming device in order to produce a response profile which automatically predictively attempts to nullify the effects of the mechanical torque disturbance.
Abstract: A burden caused by handling a large number of unique identifying information pieces such as authentication keys is to be lightened from both the user side and the protector side such as application creators. A proof data verification device sends authentication data to a proof data generation device. Signature data generation means and presignature data generation means in the proof data generation device cooperate with each other to generate proof data (a signature based on a discrete logarithm problem) from the received authentication data as well as held user unique identifying information and an access ticket, and send the proof data back to the proof data verification device. Verification means in the proof data verification device verify the signature, and if the verification is successful, the execution of program is allowed.
Abstract: Efficient and optimum printing is enabled using multiple, different models of printers. When a scanner receives a multiple simultaneous output instruction from the operator, the instruction of multiple simultaneous output, printing instruction information specified by the operator (such as the number of prints, duplex printing and stapling) and multiple pieces of image data produced according to multiple models of printers are transmitted to a printing management server. When the printing management server receives the multiple simultaneous output instruction, the printing instruction information and the multiple pieces of image data, the server stores and manages the printing instruction information and the multiple pieces of image data in association with each other. Image data corresponding to a desired printer is transmitted based on the stored and managed data.

A latch is used to hold the finisher module to the copier in a closed position.
Abstract: A method is provided for rendering a color image with a plurality of separations with a multi-level successive-filling halftoning process using a single screen for a plurality of separations. For a separation to be processed, first, from the possible multiple levels for the separation, the set of levels that would be used and the number of dots corresponding to the different levels are decided. These decisions are based on the input level for the separation and input levels for the prior process separations. The location of the dots to be printed for the different levels for the separation is then decided by using the halftone screen, while simultaneously taking into account the placement of printed dots for the prior separations. The selection is done so as to best disperse dots and minimize overlap.

Abstract: A drive assembly for a printer includes an endless loop drive path and guide structure that allows a printhead to operate in either reciprocal or endless loop modes in which the printed traverse both a liner and an arcuate portion of the drive path. This provides a printer architecture in which a printhead may be endlessly driven at a constant speed in one direction to provide multiple print swaths separated spatially. This eliminates the need for deceleration/acceleration changes required in reciprocal printer architectures and is capable of increased throughput by defining arcuate turnaround zones that can be traversed by the printhead faster than the time it takes to slow, stop and reverse a conventional reciprocal printhead assembly. This robust printer architecture also allows flexibility in use of multiple printheads with simultaneous printing, simultaneous both side printing, and duplex capabilities.
Abstract: The present invention provides an element organization support apparatus, an element organization support method and a storage medium for facilitating the addition, deletion or modification of executive elements. This is an element organization support apparatus in which, upon receiving the input of a project to be accomplished including plural tasks from an input unit, a modeling processor searches an activity database for activity data with processible tasks as keys, selects and displays on a display unit real activity candidates, and reads out of a hard disk and displays information on past evaluation of the selected combination of real activities.
Abstract: Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. The rendered composite image may be subjected to a varying field of illumination, generated, for example, by a switched sequence of individually activated, differing illuminants. This sequenced array of illuminants causes a corresponding sequence of source images to be recovered in rapid succession, thus imparting a sense of change, such as motion, between or within the recovered source images.
