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.

Abstract: A printer uses closed loop control to keep material drops ejected by a printhead within a predetermined range. The printer forms at least two objects on a support member and then operates a specular sensor array to obtain image data of the two objects on the support member. The two objects have different predetermined heights to enable a controller in the printer to identify the mass or volume of the material drops forming the objects to adjust operational parameters of the printer to maintain the mass or volume of the material drops in the predetermined range.

Abstract: A printer compensates for printing errors occurring during production of the layers for the formation of an object in a three-dimensional printer. The printer includes an optical sensor that generates data corresponding to edges of each layer of the object after each layer is printed. Differences between the raster data used to eject the material to form a layer and the data received from the optical sensor are used to modify the raster data that operates a printhead to form a next layer in the object.

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.
