Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.

Abstract: A device for inverting a sheet along a path in an electric photographic printing machine. A gateless sheet inverter is provided in which a curved portion of a sheet path branch intersects a second portion of the sheet path to form a curved inverter throat. As the sheet is driven from the curved branch portion of the path into the throat portion the beam strength of the sheet causes the trail edge of the sheet to flip foward a second nip leading to the second sheet path. A pair of reversing rolls captures the lead edge of the sheet to be inverted and then reverses to drive the sheets out of the second nip formed by a tri-roll arrangement. A sheet having a radius of curvature equal to or greater than the radius of curvature of the throat will be guided along the throat baffle and fed through the second nip. To further assist in assuring the tra il edge flips to the second sheet path an air knife can be added at the intersection of the path branches to assist in moving the trail edge into th e second path branch. A fixed deflector can also be added and configured so that the trail edge of the sheet is guided into the second branch of the sheet path to increase the lattitude of sheet curvature that can be handled by the device, the deflector further having a curved radius on the portion of the deflector contacting the sheet so that coated sheets are not damaged.

Abstract: A method evaluates printhead position in a staggered full width array (SFWA) printhead assembly (230). The method includes selecting a first printhead configuration (232,234,236,238) for printing a first test pattern on an image receiving member, generating positional correction data for roll and stitch displacements obtained from captured image data of the first test pattern, comparing the positional correction data to at least one threshold in a displacement range, and operating at least one printhead actuator (220) in accordance with the positional correction data in response to the positional correction data exceeding at least one predetermined threshold in the displacement range.

Abstract: PROBLEM TO BE SOLVED: To correct the stitch and roll errors in an image forming device.
SOLUTION: This image forming device with a sandwich arrangement type full width array print-head assembly includes: the step of selecting a first print-head setting for printing a first test pattern on an image receiving member; the step of producing positional correction data against the displacements of the roll and stitch obtianed from the image data taken in from the first test pattern; the step of comparing the positional correction data with at least one threshold value in a displacement range; and the step of operating at least one print-head actuator in accordance with the positional correction data in response to the positional correction data, which exceeds at least one predetermined threshold value in the displacement range.

Abstract: PROBLEM TO BE SOLVED: To reduce cost and to enhance the reliability of a device by eliminating a large number of moving parts in a sheet reverser or feeder.
SOLUTION: The sheet reverser 20 includes a curved sheet passage 26. A sheet driver 24 is disposed to receive a sheet along the sheet passage, leads in the sheet and reverses the moving direction of the sheet. An outlet passage 18 is disposed to receive the sheet from the sheet driver. A reverser passage 18 is disposed to receive the sheet from the sheet driver. A first immobile part 23 for leading the sheet toward the outlet passage is disposed at the starting point of the outlet passage, and a second immobile part 25 for leading the sheet toward the reverser passage is disposed at the starting point of the reverser passage. The sheet is fed to the outlet passage or the reverser passage depending on how far the sheet is led in by the sheet driver.

Abstract: PROBLEM TO BE SOLVED: To efficiently shorten a medium processing passage to enhance the reliability of the processing passage and to reduce the size of the whole machine in a parallel printing system. SOLUTION: The printing system 10 is provided with a plurality of marking engines 12, 14, a paper feeding device and a medium outlet conveying part; a highway passage 24 for conveying documents at a first speed through the system; and a reverser 92 disposed between the highway passage 24 and at least one marking engine 12. The reverser 92 is constituted to selectively reverse and convey the documents at a second speed (slower than the first speed for image formation) through at least one marking engine 12 and to buffer the difference between the first speed and second speed (to prevent influence caused by the speed difference between the first speed and second speed).
