  • Publication number: 20090322821
    Abstract: An image-forming apparatus is capable of performing a non-margin recording operation without a margin on a recording medium and providing a waiting time between a moment of termination of a movement of a carriage in one of opposite directions and a moment of initiation of a subsequent movement of the carriage in the other direction, if the non-margin recording operation is performed during the movement of the carriage in the above-indicated one direction. The carriage is moved in the other direction (returned) at a speed lower than that of the movement in the above-indicated one direction, so that the back surface of an edge portion (e.g., leading end portion) of the recording medium is protected from contamination with an ink mist produced from the ink droplets.

  • Patent number: 7628394
    Abstract: This invention is related to a feeder for transporting a print medium from a tray along a U-shaped transporting path. The feeder includes a movement member coupled to a feeding roller. The movement member includes a first portion located at a position such that the print medium makes contact with the first portion when a transporting roller and the feeding roller simultaneously make contact with the print medium. The first portion receives a force from the print medium when the first print medium makes contact with the first portion. The movement member moves the feeding roller by utilizing the force such that a distance between the feeding roller and the support surface of the tray increases.
