20080205818 | Image null-balance system with multisector-cell direction sensing - A light beam is detected/localized by multisector detector—quad-cell, or 5+ sectors handling plural beams. Preferences: Beams focus to diffraction limit on the detector, which reveals origin direction by null-balance—shifting spots to a central sector junction, and measuring shifts to reach there. One or more MEMS reflectors, and control system with programmed processor(s), sequence the spot toward center: following a normal to an intersector boundary; then along the boundary.

The system can respond toward that (or a related) direction. It can illuminate objects, generating beams reflectively. Optics define an FOR in which to search; other optics define an FOV (narrower), for imaging spots onto the detector.

The device body has a main body, which has a driving member that rotates the rotational body and the extension portion, a detecting unit for detecting a movement of the extension portion, and a determining unit for determining a type of the developer cartridge using either a time elapsed between a time in which the driving member begins driving the rotational body and a time in which the detecting unit detects the movement of the extension portion, or a drive amount of the drive device occurring during an elapsed time. | 2008-08-28 |
20080205912 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREOF - In an image forming apparatus, papers are taken in one by one using an auto document feeder (ADF) provided with a media sensor to determine the type of papers and successively carried to the reading position while the type of the papers are determined and displayed on the control panel. By inputting the type of image forming media corresponding to the type being displayed from the control panel, an image is formed at a desired image quality. | 2008-08-28 |
20080205913 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREFOR - An image forming apparatus that is capable of normally performing second side printing on a transfer material, even if the transfer material put on standby after completion of first side printing is pulled out by a user. A transfer material having image formed on its first side is fed until it is partly exposed to the outside of a printer, and is then fed to a refeeding path in the printer and further fed to a standby position prior to image formation on the second side of the transfer material. When it is detected that the transfer material caused to stop at the standby position is pulled out by a user, a warning to stop pulling out the transfer material is given to the user. | 2008-08-28 |
20080205914 | IMAGE FORMING APPARATUS AND JAM-REMOVAL METHOD THEREOF - An image forming apparatus including an image forming apparatus body having an aperture for the removal of a jammed printing medium, a printing engine installed in the image forming apparatus body to print an image on a printing medium supplied thereto, and a jam-removal device installed to the image forming apparatus body in an upwardly movable manner, so as to remove a jammed printing medium from the image forming apparatus body. As the jam-removal device, capable of opening or closing the aperture for the removal of the printing medium jammed in the body, can be sliding moved in an upward direction of the image forming apparatus body, the image forming apparatus can achieve a reduced installation space thereof. | 2008-08-28 |
20080205915 | Image Forming Apparatus - An image forming apparatus includes a first cabinet, a toner carrier, an image carrier, a second cabinet disposed adjacent to the first cabinet, a toner amount detector and an empty decision unit. An inside of the first cabinet is communicated to an inside of the second cabinet through a plurality of openings. A spacing between one outer edge of one opening provided in one end side and another outer edge in a direction opposite to the longitudinal direction of another opening provided in another end side has a width not less than a width of an image forming region. The empty decision unit decides that a remaining state of a suspension polymerization toner in the second cabinet is the empty state before the amount of suspension polymerization toner in the second cabinet becomes smaller than the amount of suspension polymerization toner in the first cabinet. | 2008-08-28 |
