| 20120069375 | PRINTING DEVICE, PRINTING CONTROL METHOD AND RECORDING MEDIUM - A LAN control unit receives print data from a client device or the like. An input job storage unit registered on a hard disk a series of PDL commands included in the print data received. An input job queue management unit registers print job specifying information specifying a print job represented by the print data received to the end of an input job queue. A PDL interpretation/execution unit successively executes from the head of the series of PDL commands stored on the hard disk device. When it is determined that the PDL command that has been executed is a re-execution unnecessary command, the PDL interpretation/execution unit overwrites the PDL command stored on the hard disk with a NOP command. | 03-22-2012 |
| 20120069374 | PRINTING DEVICE, PRINTING SYSTEM, PRINTING CONTROL METHOD AND RECORDING MEDIUM - A conversion unit converts a command part of an image inclusion command into an internal command. A first memory unit stores an image non-inclusion command and the internal command converted by the conversion unit. A second memory unit stores an image data part of the image inclusion command. A restart page number memory unit stores restart page number information when a print process being executed is interrupted in order to execute an interruption print process. When restarting the interrupted print process, a control unit executes control to read out the internal command and the image non-inclusion command stored in the first memory unit up to the page indicated by the restart page number information, and from the page indicated by the restart page number, further executes control to read out from the second memory unit the image data part following the internal command read out from the first memory unit. | 03-22-2012 |
| 20120020707 | ACHROMATIC APPARATUS FOR ACHROMATIZING ACHROMATIC TONER IMAGE FORMED ON RECORDING MEDIUM - An achromatic apparatus achromatizing an achromatic toner image on paper by an achromatic toner containing a near-infrared ray absorbing colorant that is a cyanine-based colorant, and an organic boron-based compound includes heater units each of which are a ceramic heater arranged across an achromatic convey path of an achromatic unit, and light source units each of which include an LED array chip having a center wavelength shifted to the long-wavelength side from the peak of the first absorption band of the near-infrared ray absorbing colorant and within a predetermined wavelength range. While the paper formed with the achromatic toner image is being conveyed through the achromatic convey path at a liner speed of equal to or faster than 15 mm/sec, the achromatic toner image is heated to a predetermined temperature, and is irradiated with achromatic light from the LED, and thus achromatized efficiently at a low energy consumption. | 01-26-2012 |
| 20110299860 | IMAGE FORMING APPARATUS AND TONER REFILLING METHOD THEREFOR - In a new printer, a toner cartridge is mounted in the state where there is no toner in a reserve tank, and toner of the amount of filling toner D therein is supplied with the amount of full accommodation toner E for filling up the reserve tank by a toner supply mechanism. The toner of the amount of remaining surplus toner F remains in the toner cartridge. The amount of toner consumption G is measured by a dot counter during a printing execution. In the case where a toner density sensor detects a toner decreasing, the toner is supplied to a developing unit from the reserve tank. When it becomes G>F, it display-informs a user of “toner cartridge exchange is allowed”. Hereby, it enables to exchange the toner cartridge without stopping operation of the main body of the image forming apparatus using a two-component developer. | 12-08-2011 |
| 20110292418 | COLOR PRINTER WITH POWER SAVING RECORDING HEAD - The present invention relates to a color printer and particularly to a color printer reducing power consumption and complying with international criteria ensuring sustained earth environment. In a color printer having multiple optical writing heads for individual recording colors, the activated periods of individual color recording heads are set to different periods and one writing period of individual recording heads is divided into multiple periods, video data for recording one dot line are divided into multiple blocks in the main scan direction, and the divided video data are used for emission at different times in the sub-scan direction, whereby a smaller number of optical writing elements are simultaneously driven for emission and the peak power consumption of the entire apparatus is reduced. | 12-01-2011 |
| 20110286773 | IMAGE FORMING APPARATUS - Provided is an image forming apparatus whose primary transfer roller is structured in a way as to move from a transfer position along a locus of a rotational motion of a radius r about a rotational center of a photosensitive drum as a rotational axis so that the transfer position is set to a position shifted downstream in a belt moving direction from a position of contact between the photosensitive drum and an intermediate transfer belt by a shift amount f. Accordingly, even when there is an error the upward/downward movement of the primary transfer roller to shift the position of contact, the distance of the primary transfer roller from the circumferential surface of the photosensitive drum is constant, so that the shift amount f which is the tangent of the circumferential surface of the photosensitive drum and the circumferential surface of the primary transfer roller is always set constant. | 11-24-2011 |
| 20110138215 | CLOCK SIGNAL GENERATING DEVICE AND ELECTRONIC DEVICE - To provide a clock signal generating device that changes the frequency of a predetermined clock signal in a short time and prevents or mitigates instability in the operation of the supply destinations of the clock signal when the frequency of the clock signal is changing. | 06-09-2011 |
| 20110026056 | IMAGE FORMING DEVICE AND POWER CONSUMPTION CONTROL METHOD IN AN IMAGE FORMING DEVICE - The present invention provides an image forming device that reduces power consumption by setting the color image recording units to low power consumption mode during monochrome image recording, and a power consumption control method in an image forming device. Furthermore, this image forming device has a monochrome image recording unit and color image recording units, and is an image forming device capable of setting the monochrome image recording unit and color image recording units to low power consumption mode, and has a switching unit for switching between monochrome image recording and color image recording, and a control unit that sets the color image recording units to low power consumption mode during monochrome image recording and continues to set the color image recording units to low power consumption mode while this monochrome image recording continues. | 02-03-2011 |
| 20110013952 | INTERMEDIATE TRANSFER BELT AND ELECTRO-PHOTOGRAPHIC IMAGE FORMING APPARATUS WITH INTERMEDIATE TRANSFER BELT - An intermediate transfer belt is built in an electro-photographic image forming apparatus. A toner image formed on a photosensitive element is primary transferred on the intermediate transfer belt. The intermediate transfer belt secondary transfers the primary transferred toner image on a recording medium being conveyed at a secondary transfer unit. The intermediate transfer belt has streaks formed by surface roughening on the surface thereof and directed so as to have an angle relative to the driving direction of the intermediate transfer belt within a range from 40 to 140 degree. This angle setting enables stable transfer of an image without causing any character missing. | 01-20-2011 |
