Abstract: Ein 3D-Objektdrucker stößt Tropfen eines Werkstoffs aus einer Vielzahl von Düsen in einem ersten Druckkopf aus, um ein Objekt auf einem ersten Bereich eines Elements zu bilden, und stößt Tropfen eines Stützmaterials aus einer Vielzahl von Düsen in einem zweiten Druckkopf aus, um das Objekt auf dem ersten Bereich des Elements zu stützen. Der zweite Druckkopf stößt Tropfen des Stützmaterials auf einen zweiten Bereich des Elements aus, der vom ersten Bereich getrennt ist, um eine Substratschicht zu bilden. Der erste Druckkopf stößt Tropfen des Werkstoffs auf die Substratschicht aus, um ein gedrucktes Testmuster zu bilden. Ein Bildsensor generiert Bilddaten des gedruckten Testmusters, um eine defekte Düse im ersten Druckkopf zu erkennen.

Abstract: A method for preserving image squareness and image on image registration in a system having a plurality of imaging stations, each imaging station having a raster output scanner (ROS (13)). The method includes adjusting the target skew of a reference ROS within one of the plurality of imaging stations by the angular difference (40) between the actual reference ROS position (38) and the target position (42) for the reference ROS and adjusting the target skew of the reference ROS by the skew of the reference ROS relative to the desired skew for image (37) squareness.

Abstract: The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of a n image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error, determining margin shifts to compensate for the residual magnification error, and applying the margin shifts. Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image mov es away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.

Abstract: A method and system for repositioning a mark (105,110) on a belt (100) after an image on paper registration process, which includes printing a test pattern, measuring at least one test pattern parameter, detecting a mark on the belt and detecting at least one imaging error associated therewith, using the at least one test pattern parameter and the at least one imaging error to determine the lateral distance required to shift a particular image to a desired location (115,120) on the belt, and shifting the image to the desired location.

Abstract: The relationship between first and second side images is evaluated to determine how the position of the paper and/or the size and arrangement of an image can be manipulated to compensate for paper shrinkage caused by fusing. Show through is reduced by performing setup (S2000) to adjust a pixel clock frequency and/or a photoreceptor speed, determining a residual magnification error (S3000), determining margin shifts (S4000) to compensate for the residual magnification error, and applying the margin shifts (S5000). Paper shrink effects on registration can be compensated for using determinations made during a typical printer setup. Show through errors can be reduced without using a paper conditioner to pre-shrink or re-wet the paper. In simplex and duplex printing, the show through errors worsen as the image moves away from the registration edge. Using information obtained during setup, a margin shift is determined that results in a significant reduction in the maximum show through for each image.
