    Abstract: An approach is provided for managing the processing of print data at a printing device based upon available consumable resources. A printing device includes a print process configured to determine consumable resources that are currently available at the printing device. The print process is further configured to determine which print data is to be processed based upon the consumable resources currently available at the printing device and the consumable resources required to completely process each of the print data. Print data that can be completely processed using the currently available consumable resources are selected for processing. The print process may also be configured to cause a notification to be provided to a client device to indicate the consumable resources currently available at a printing device and/or that insufficient consumable resources were available to process particular print data and to recommend other consumable resources to process the particular print data.

    Abstract: According to one embodiment, a sheet type determination apparatus includes a tray, light source, detection unit, database, and operation unit. The tray is configured to hold a sheet bundle formed by stacked sheets. The light source emits illumination light to a first region. The detection unit detects a light intensity distribution of transmitted light emerging from a second region. The transmitted light is generated as the illumination light passes through the sheet bundle, and the second region is different from the first region. The database stores a table describing a relation between reference attenuation rates and types. The operation unit is configured to calculate an attenuation rate of the transmitted light based on the light intensity distribution, and determine a type of the sheets by comparing the attenuation rate with the reference attenuation rates.

  • Patent number: 7957687
    Abstract: Preventing a paper jam as much as possible when actual paper size differs from designated paper size with increasing throughput by starting conveyance of a second sheet before detecting the length of a first sheet. Unless a register sensor has detected the rear edge (step S303), start of feeding the next sheet is checked (step S304). If started, a prescribed value 1 is applied (step S305). If not started, a prescribed value 2 is applied (step S306). Unless the rear edge is detected before a timer measures “estimated time+prescribed value” (step S307), a paper jam decision is made (step S308). If the rear edge is detected before the timer measures the “estimated time+prescribed value” (step S303), the processing is completed without making a paper jam decision. Making the prescribed value 1 less than the prescribed value 2 enables reducing the paper jam caused by incorrect setting.

    Abstract: There is provided a recording medium imaging device capable of properly selecting pixels used for determining the kind of the recording medium from the captured surface image to remove pixels from which the surface property of the recording medium cannot be properly determined because the pixels extremely high in light quantity are affected by some sort of dirt or scratches in determining the kind of a recording medium. This allows the determination of kind of the recording medium based on the normally captured surface image to reduce the decrease in accuracy in determining the kind of the recording medium.

  • Patent number: 7848696
    Abstract: The invention provides an image forming apparatus wherein, when forming an image on transfer sheet, the transfer sheet is shifted across the width immediately before transfer of the image onto transfer sheet based on the position of a toner image formed on an intermediate transfer member as an image carrier, and the misalignment across the width is adjusted, thereby ensuring high-speed and high-precision adjustment of the position of the image formed on a single side or both sides.

  • Patent number: 7835685
    Abstract: An image forming apparatus capable of reducing a part of a sheet exposed outside the apparatus on standby after finishing printing a first side in both-sided printing. A transfer material P having an image formed on its first side is fed until a part thereof gets exposed outside a full-color printer 1 and is fed to a refeeding path in the full-color printer 1. The transfer material P inverted by a flapper 44 is fed to a standby position to form an image on a second side thereof and is stopped there. In the case where a preparation for forming the image on the second side is not completed, the standby position for having the transfer material P stopped is changed corresponding to length of the inverted transfer material P in a feeding direction.

    Abstract: In an image forming apparatus, a type of paper conveyed through a conveying path is determined based on combination of sensing signals obtained from a plurality of sensing units. Each of the sensing units is movable between an actuating position and a retracting position as a paper is conveyed through a conveying path. Based on the type of paper determined based on combination of sensing signals obtained from the plurality of sensing units, a control unit of the image forming apparatus controls an image forming unit forming an image on the conveyed paper.

  • Publication number: 20100239343
    Abstract: An image forming device makes a sheet pass between first rotating member and separator in a pressed position, causes second rotating member pair to transport a sheet, transports the sheet from second rotating member pair with the sheet held between third rotating member and image carrier in a transfer position, transfers an image formed on image carrier onto the sheet, and suspends rotation of first rotating member when a portion of the sheet, which is distance L away from the sheet's rear end, passes the pressed position. Provided that length 1?(M+L) and length 2<(M+L) where M is a distance from the pressed position to the transfer position, when the sheet has length 2 in a transport direction, the device delays image formation start and/or advances sheet transport start, by a predetermined time period as compared to when the sheet has length 1 in the transport direction.

  • Patent number: 7783211
    Abstract: An image forming apparatus of the invention conveys paper fed by a paper feeding mechanism piece by piece to a paper discharging unit through a paper conveying path. An image forming unit is arranged in a midway portion of this paper conveying path and executes an image forming process for printing an image based on image data on paper being conveyed. A sensor that detects a type of the paper conveyed is arranged on an upstream side with respect to the image forming unit on the paper conveying path. Image forming process conditions for the image forming unit are set in accordance with a detection result of the sensor. When the paper fed to the paper conveying path is paper not detected by the sensor, the image forming process is started awaiting a detection result by the sensor. On the other hand, when the paper is detected by the sensor, the image forming process is started without awaiting paper type detection.

  • Patent number: 7731181
    Abstract: A paper feeding apparatus with a paper size determining means includes a paper tray, paper guide, a belt, a roller set, a sensing mechanism and a control unit. The paper tray has a front surface for supporting paper and a rear surface. The paper guide is movably disposed on the paper tray and for abutting against an edge of the paper in the paper tray. The roller set is rotatably disposed on the rear surface. The belt, connected to the paper guide and wound around the roller set, synchronously moves the paper guide and rotates the roller set. The sensing mechanism disposed on the rear surface senses a to-be-sensed component disposed on the belt or the roller set and thus outputs a sensing signal. The control unit receives the sensing signal and thus determines size of the paper.
