  • Patent number: 7853160
    Abstract: The goal of the present invention is, while waiting for reserved printing that is to be executed at a future time, even in a case where new printing is executed before then, to compare the remaining amount of consumable material to the amount of consumable material necessary for the designated reserved printing. The terminal apparatus that sent the printing data to execute new printing is notified about the condition of the consumable material. The present invention detects a lack of consumable material by comparing the remaining amount of consumable material to the amount of consumable material necessary for the reserved printing. Therefore, a user using the terminal apparatus can be informed about the information concerning the consumable material by having the terminal apparatus, which newly sent the printing data, notified of the information concerning the detected consumable material.

  • Patent number: 7764922
    Abstract: In a housing in which a printing unit is provided, a printed-paper storing unit that stores paper printed by the printing unit is provided to be removable to the outside. This printed-paper storing unit can be brought into a lock state in which removal to the outside of the housing is physically prevented by a fixing mechanism. When a print job sent from a user side designates internal storage of printed paper, the printed-paper storing unit is fixed in the housing by the fixing mechanism and locked. An unlock number of a number selected at random is notified to the user side to perform printing. After the printing is finished, the finish of the printing is notified to the user side and the lock state is released according to input of the unlock number to make it possible to remove printed paper to the outside.

  • Patent number: 7761046
    Abstract: Mechanism unit(s) functioning as automatic-feed cassette(s) and mechanism unit(s) functioning as manual-feed tray(s) together form a single integral module, constituting a hybrid paper supply module. A plurality of hybrid paper supply modules are stacked together to constitute a paper supply mechanism. Manual-feed tray(s) with which manual-feed mechanism unit(s) of respective hybrid paper supply module(s) is or are provided is or are maintained in stored state(s) as a result of electromagnetic attraction produced by electromagnet(s). In correspondence to image forming condition(s), electromagnetic attraction at one electromagnet is terminated, causing manual-feed tray(s) to assume deployed state(s). Furthermore, primary path(s) passing vertically through module interior(s) is or are formed so as to permit transport of recording paper toward printing unit(s) of hybrid device(s) regardless of from which hybrid paper supply module(s) it is that recording paper is taken up.

  • Patent number: 7753605
    Abstract: A tape drive for use in for example a transfer printing apparatus to drive a printer ribbon. The printer ribbon is mounted on two spools each of which is driven by a respective stepper motor. A controller controls the energization of the motor such that the ribbon is transported in at least one direction between spools mounted on the spool support. The controller is operative to energize both motors to drive the spools of ribbon in the direction of ribbon transport to achieve push-pull operations. Ribbon tension is monitored to enable accurate control of ribbon supply and ribbon take-up, the ribbon tension being monitored, for example, by monitoring power supply to the two stepper motors.

  • Patent number: 7747212
    Abstract: A sheet processing apparatus of the invention includes a post-processing unit that applies post-processing to sheets conveyed from an image forming apparatus, a vertical aligning unit that conveys the sheets to the post-processing unit and brings an edge of the sheets into contact with a movable stopper arranged in a conveying path for the sheets to align the sheets in a conveying direction, and a horizontal aligning unit that holds the sheets with a pair of movable aligning plates from both sides along the conveying direction to align the sheets in a direction orthogonal to the conveying direction. The sheet processing apparatus further includes a control unit that switches a position of the stopper according to a size of the sheets and controls the aligning plates to be located on both sides close to the center of the sheets when the sheets are brought into contact with the stopper.

  • Patent number: 7734243
    Abstract: In an image forming apparatus of the present invention, an idle roller once stops rotating when a front edge of a sheet conveyed reaches the idle roller. The idle roller restarts rotating at such a timing that a front edge of a toner image on a photoreceptor and a front edge of an image writing position on the sheet are aligned with each other. Then, even if a rear edge of the sheet is still in the idle roller, the idle roller stops rotating when the front edge of the sheet is sandwiched between a transfer roller and the photoreceptor. By carrying out such operations, it is possible to avoid by a very simple way an occurrence of a slip phenomenon that is a phenomenon of slipping of the sheet with respect to the photoreceptor while suppressing a reduction in image quality as much as possible. In addition, it is also possible to surely secure a blank space formed at a rear edge portion of the sheet.

  • Patent number: 7421241
    Abstract: Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.
