  • Patent number: 9878870
    Abstract: According to an example, to eject print media from an image forming apparatus, a variable page feed velocity of a first page of print media exiting a feed zone is detected. An acceleration value and a deceleration value based on the variable page feed velocity of the first page is calculated. The calculated acceleration is applied to a media movement component in the output zone when the entire first page has cleared a media sensor in the front of the output zone, and the deceleration is applied when the tail end of the first page is in a brake zone. In some examples, a second page of print media and a variable page feed velocity of the second page exiting the feed zone is detected, and the media movement component in the output zone is accelerated to match the variable page feed velocity of the second page.

  • Patent number: 8699098
    Abstract: A scanner comprises a first gear assembly on a frame, a stationary scan surface having a first width, and a scan module having a length substantially less than the first width. The scan module includes a second gear assembly configured to move the scan module, in a first orientation generally perpendicular to the first width, in a first scanning path relative to a first width portion of the scan surface and in a second, non-duplicative scanning path relative to a second width portion of the scan surface. The second gear assembly is releasably engageable to the first gear assembly to selectively shift the scan module, in a second orientation generally perpendicular to the first orientation, between the respective first and second scanning paths.

  • Patent number: 8693017
    Abstract: There is provided an image forming apparatus capable of realizing a trial printing function that minimizes unnecessary consumption of time and supplies. Images that are inputted are accumulated in a memory. An output mode is set and a setting is made as to whether trial printing is to be carried out in the output mode or not. A CPU provides control to read out a corresponding image from the memory according to the set output mode and form the readout image on a sheet. When it is determined that the trial printing is to be carried out during image formation according to the set output mode, the CPU provides control to set the number of trial print pages according to predetermined conditions and carry out the trial printing for the set number of trial print pages.

  • Publication number: 20140064812
    Abstract: A pair of opposing rollers comprises a first roller and a second roller contacting the first roller to form a nip between the rollers through which print media passes. Because of surface irregularities in the rollers, the nip can have one or more unintended gaps at locations where the surface of the first roller separates from the surface second roller. Further, a frame holds the first roller and the second roller. A manual or automatic axis adjuster is operatively connected to the controller and the first roller. The axis adjuster changes the angle of the axis (a first axis) of the first roller relative to the axis (a second axis) of the second roller based on the gap to position the first axis in a position other than parallel to the second axis. Changing the angle of the first axis relative to the second axis reduces or eliminates the gap.

  • Patent number: 8599451
    Abstract: A sheet conveyance device that is capable of correcting skew of a sheet like an index sheet without complicating a use setting and without increasing a cost significantly. A plurality of conveyance units are arranged in a direction intersecting a sheet conveyance direction to convey a sheet. At least three detection sensors are arranged in a direction intersecting the conveyance direction at an upstream side from the conveyance units to detect the sheet. A skew amount computation unit measures a time difference between detection timings of a front end of the sheet by two of the at least three detection sensors except the detection sensor that detects first, and computes a front-end skew amount according to the time difference. A speed change unit makes the conveyance speeds of the conveyance units be different according to the front-end skew amount so as to correct the skew of the sheet.
