  • Publication number: 20200370883
    Abstract: A sheet distinction device includes a measurer, a housing, a shutter, a calibration plate, and a controller. The measurer emits light to a sheet, receives light reflected from the sheet, and acquires detection information for determining physical properties of the sheet. The housing houses the measurer and is provided with an opening through which the emitted light and the reflected light pass. The shutter switches between a closed state in which the opening is closed and an open state in which the opening is open. The calibration plate is provided on a surface of the shutter which is on an inner side in the closed state. In the closed state, the measurer emits light to a calibration plate and receives reflected light to acquire acquisition information. The controller calibrates the measurer based on the acquisition information.

  • Patent number: 9207584
    Abstract: An improved image forming apparatus is described which can inhibit the quality of printed images from being degraded. A control unit performs a steering operation to shift an intermediate transfer belt toward a target belt position by controlling the inclination angle of a steering roller. Also, a memory stores the inclination angle of the steering roller in association with the operational states of rotary members facing the intermediate transfer belt. The control unit updates the values stored in the memory with an update value. When the result of detecting the belt edges indicate that the intermediate transfer belt falls in a predetermined range around the target belt position during the steering operation, the control unit determines the update value on the basis of the steering duration time and the inclination angle of the steering roller.

  • Patent number: 9031429
    Abstract: A sheet of paper is set on a paper-supplying portion of a top surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures gloss level of the top surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. Based on this comparison, it is determined whether or not the gloss processing has been performed on the top surface thereof. When determining that the gloss processing has been already performed, a warning message such that the gloss processing has been already performed on the top surface of the sheet, of paper is displayed on a screen. On the other hand, when determining that the gloss processing has not performed, the top surface gloss processing apparatus performs the gloss processing on the top surface thereof.

  • Patent number: 8783683
    Abstract: An image forming apparatus acquires sheet information indicating paper weight or the like of a transported sheet of paper. The apparatus also has a control portion and shifts a reference position which has been previously set to a direction orthogonal to a transporting direction of the sheet of paper based on the paper weight or the like of the transported sheet of paper. A deviation sensor detects a deviation of the sheet of paper with regard to the shifted reference position along the direction orthogonal to the transporting direction of the sheet of paper. A sheet shift portion shifts the sheet of paper to the shifted reference position based on the deviation detected by the deviation sensor.
