Abstract: Apparatuses include, among other components, a conveyor belt and at least one roller supporting the conveyor belt, etc. The belt moves in a processing direction as the roller rotates. The exterior surface of the roller has roller outer sections and a center crowned portion between the roller outer sections. The belt has belt outer sections and a belt center section between the belt outer sections. The belt outer sections contact the roller outer sections, and the belt center section contacts the center crowned portion of the roller. The belt outer sections have a lower flexibility, and the belt center section has a relatively higher flexibility. The flexibility difference between the higher flexibility and the lower flexibility biases the belt outer sections toward the center crowned portion of the roller and maintains the belt center section so that the belt center section is self-aligned with the center crowned portion of the roller.

Abstract: Embodiments described herein are directed to generating physical three-dimensional color-accurate objects based on a 3D computer-based color model using printed layers of media. Embodiments can slice a 3D computer-based color model into 3D cross-sectional components, which retain the color information of the model. The 3D cross-sectional segments can be converted into 2D page images and the color information can be included in a plan image corresponding to the cross-sectional segments. Embodiments can print the page images to form cross-sectional prints which can be layered and trimmed to shape the prints into a color accurate physical object that represents the model.

Abstract: An apparatus for transferring load in a sheet-feeding system is described. The apparatus employs a rack, which is vertically movable between a loading position and a rack transfer position. The rack has a ribbed structure. Further, a movable cart in the apparatus can shift between a cart transfer position, an external position, and an unloading position. The cart, like the rack, is also a ribbed structure including a number of ribs. The rack ribs and the cart ribs are positioned to intercalate in the respective rack and cart transfer positions. In addition, the apparatus facilitate elevation of the cart from the floor once the load is transferred from the rack to the cart.

Abstract: A vacuum control assembly for use in an image production device is provided. The assembly has a plenum, a perforated plate, a plurality of valve assemblies, and a controller. Each valve assembly has a rotating valve having a vacuum passage, and a chamber body having a plurality of chambers. Each valve is rotatable between a first position that fluidly connects the vacuum passage with at least one of the chambers to complete a fluid path between the plenum and the perforated plate, and a second position at which the vacuum passage connects the plenum with none of the chambers. The controller controls the plurality of valve assemblies to provide vacuum to a first predetermined portion of the perforated plate while also providing no vacuum to a second predetermined portion of the perforated plate.
