  • Patent number: 9616689
    Abstract: A transport mechanism and method are provided for transporting sheets of a print medium in a printing system. The transport mechanism includes a first conveyor device having a first conveyor body configured to hold a plurality of sheets of print medium and to convey the sheets along the transport path, and a transfer system including a second conveyor device having a second conveyor body configured to hold the sheets and to convey the sheets further along the transport path. The transfer system is configured to transfer the sheets from the first conveyor body to the second conveyor body in a transfer region. The second conveyor body is adjacent the first conveyor body in the transfer region, and the transfer system includes a suction device configured to provide an under-pressure at the second conveyor body for contactless transfer of the sheets from the first conveyor body to the second conveyor body.

  • Patent number: 9440466
    Abstract: A transport mechanism is provided for transporting sheets of a print medium in a printing system. The transport mechanism include a first conveyor device having a first conveyor body which is configured to support a plurality of sheets of print medium, the first conveyor body being movable to convey the sheets along the transport path in the printing system; and a transfer system including a second conveyor device having a movable second conveyor body for supporting the sheets of print medium and conveying the sheets further along the transport path, the transfer system being configured to transfer the sheets of print medium from the first conveyor body to the second conveyor body in a transfer region. The second conveyor body is arranged adjacent or proximate to the first conveyor body in the transfer region, and the transfer system includes spacer means which is configured to maintain a predefined spacing between the first conveyor body and the second conveyor body in the transfer region.

  • Patent number: 6478405
    Abstract: The present invention relates to a printer comprising a printhead fixed on a scanning carriage, movement structure to move the scanning carriage and a receiving material with respect to one another in a main scanning direction and a sub-scanning direction, substantially perpendicularly to the main scanning direction, and a guide structure to guide the scanning carriage in the main scanning direction. The printer also comprises a displacement structure to displace the scanning carriage automatically with respect to the guide structure during the movement of the scanning carriage in the main scanning direction.

  • Patent number: 5715100
    Abstract: An optical adjustment arrangement for a scanning system comprises a main part having defined thereon a triangle with a center point and first and second base points. An optical part is positioned onto the main part so that the center point is aligned with the optical axis of the optical part. The right and left sides of the optical part are adjusted separately and independently by first and second adjustment devices. The position of the adjustment devices coincides with the base points of the triangle. When one of the first and second adjustment devices is moved in a direction perpendicular to the plane defining the triangle, the main part with the optical part is rotated around the line connecting the other of the first and second base points with the center point. Stabilizing parts acting as flexible hinges are preferably provided around the main part.
