Abstract: A method for printing includes the use of a protective guide system that protects a print head nozzle plate from physical contact with objects such as a curled print medium. The print head nozzle plate includes a nozzle array including a plurality of nozzles arranged in a plurality of subarrays. The plurality of subarrays are spaced from each other by a plurality of intranozzle areas devoid of nozzles. The protective guide system includes a frame and a plurality of cross members aligned with the intranozzle areas between the subarrays. The protective guide system thus protects the print head nozzle plate without obstructing the ink during printing.

Abstract: A 3D printer configured to print a 3D part includes an ejector having a nozzle that is configured to eject drops of a build material. The 3D printer also includes a build plate positioned below the nozzle. The drops land and solidify on the build plate to form at least a portion of the 3D part. The 3D printer also includes a first heater positioned under or within the build plate. The first heater is configured to heat the build plate and the 3D part thereon. The 3D printer also includes a second heater positioned laterally-offset from the build plate. The second heater is configured to heat a volume of air between the nozzle and an upper surface of the 3D part. The 3D printer also includes an enclosure. The nozzle, the build plate, the first heater, and the second heater are positioned at least partially within the enclosure.

Abstract: A slicer in a material drop ejecting three-dimensional (3D) object printer generates machine ready instructions that operate components of a printer, such as actuators and an ejector having at least one nozzle, to form features of an object more precisely than previously known. The instructions generated by the slicer control the actuators to move the ejector and a platform on which the object is formed relative to one another at a constant velocity to form edges of the feature.

Abstract: A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.

Abstract: A media transport system includes a belt with a plurality of rows of holes, a vacuum plenum, and a shutter. The belt is positioned over the vacuum plenum carries a plurality of media over the vacuum plenum. A row of holes in the belt includes inter-copy gaps that separate media on the belt and the inter-copy gaps include no holes in the belt. The shutter includes a solid member that prevents a flow of air between the vacuum plenum and a portion of the belt positioned above the first shutter and a first aperture formed through the solid member that is aligned with the row of holes in the belt.

Abstract: A sheet transport apparatus includes a first belt having a first pattern of first vacuum holes, and a second belt having a second pattern of second vacuum holes. The first belt is positioned on and contacts the second belt. The first belt contacts sheets to be transported. When transporting the sheets on the first belt separated by spaces between the sheets, the first pulleys and second pulleys rotate together and the first belt and the second belt move together. When not transporting the sheets, a controller controls pulleys to move the first belt relative to the second belt so as to leave blocked-hole regions of the first belt where the spaces between the sheets are located. The blocked-hole regions are locations of the first belt where the first vacuum holes are unaligned with the second vacuum holes and the first vacuum holes are blocked by the second belt.

Abstract: A printer attenuates banding visual defects arising from a lack of flatness in media as ink is ejected onto the media. The printer includes a detector that generates a signal corresponding to the slope in the media and a controller that modulates a volume of the ink drops ejected by one or more printheads in the vicinity of the slope in the media.

Abstract: A print head protection device is used with an inkjet printer having a print head adapted for elevating. A roller is mounted upstream of the print heads and above the process path a predetermined distance. A cover on the roller outer surface contacts the sheet lead edge if sheet curl exceeds a set curl range. The cover will cause rotation of the roller by engaging the sheet. A rotary encoder is mounted for synchronous rotation with the roller. The rotary encoder generates a signal in response to rotation of the roller, raising the print head to preclude damage. Alternately, the sheet can be discarded.
