Abstract: An apparatus adapted for presenting a sheet of media to an image transfer structure. The apparatus includes a registration baffle positioned in an offset relationship relative to the image transfer structure and a pre-transfer baffle assembly including a first baffle oppositely disposed to a second baffle, the pre-transfer assembly generally forms an “S” shape and is adapted for guiding the sheet of media from the registration baffle to the image transfer structure. The pre-transfer baffle assembly is arranged in a first position adapted for guiding the sheet of media toward the image transfer structure at an angle of less than ninety degrees, and the pre-transfer baffle automatically begins rotation to a second position as the sheet of media reaches a pre-determined position within a paper path.

Abstract: An apparatus including a control cylinder rotatably supported for thermal conduction to a sheet. The sheet conveys ink deposited on a first side. The sheet is held against a peripheral arch of the control cylinder as it rotates with the first side of the sheet directly engaging and wrapping around the control cylinder along the peripheral arch. The apparatus also includes a thermal control element for heating and/or cooling the control cylinder. The apparatus also includes a pressure roll for spreading the ink. The pressure roll with the control cylinder forms a spreader nip, which is selectively changeable between a closed and open position. In the closed position the pressure roll is biased toward the control cylinder for applying pressure to the ink on the sheet. The pressure roll is spaced further away from the control cylinder in the open position relative to the closed position.

Abstract: A three-dimensional object printer generates image data of an object being formed in the printer with an optical sensor and identifies the heights of object features above a substrate on which the object is being formed. A controller operates one or more actuators to move the optical sensor at a plurality of distances above the object to generate image data of the object at a plurality of heights above the object. The controller identifies the distances of the features of the object with reference to the image data generated by the optical sensor and the focal length of the optical sensor.
