Abstract: A system for manufacturing three dimensional objects can include logic to detect, for at least one vessel, a moisture content level corresponding to a build material residing in the at least one vessel. The logic can also adjust a humidity level and a temperature of a gas and a conditioning agent applied to the at least one vessel, wherein the humidity level and the temperature are based on the moisture content level and a temperature of the build material residing in the at least one vessel. Additionally, the logic can initialize manufacturing a three dimensional object with the build material from the at least one vessel in response to detecting the moisture content level of the build material residing in the at least one vessel is within a predetermined range.

Abstract: A method of three-dimensional (3D) printing is provided. Print data is received, which defines patterns of at least one agent to be applied to a layer of build material. These patterns are at least partially based on a 3D model of at least one object to be generated. The print data print data is processed to determine regions which are distant from said patterns. The print data is modified to add a further pattern of a detailing agent to be selectively applied to the layer of build material to generate fracture regions in a processed volume of build material.

Abstract: In one example, a document scanner has a fixed-position scan bar and a built-in translatable calibration target. The scan bar has a linear array of imaging elements aimed in an imaging direction. The calibration target is spaced apart from and parallel to the linear array, and has a planar surface orthogonal to the imaging direction spanning the length of the linear array. The target is translatable during a calibration in a direction in a plane of the surface.

Abstract: In an embodiment, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to determine a media advance error for each one of multiple page regions on a media page. The instructions further cause the processor to control a media advance mechanism to compensate for the media advance error in each page region.
Abstract translation: 在一个实施例中，处理器可读介质存储代表指令的代码，所述指令当由处理器执行时导致处理器确定媒体页面上的多个页面区域中的每个页面的每一个的介质提前错误。 指令还使得处理器控制介质提前机制以补偿每个页面区域中的介质提前错误。

Abstract: A printer mechanism includes a printhead to print on a print medium, and a platen located generally adjacent the printhead such that the platen and the printhead define a print zone therebetween. The platen includes a plurality of elongate ribs that project from an upper surface of the platen in a spaced relationship and positioned to contact a lower surface of the print medium such that the print medium bends downwardly between the ribs to provide an undulated section of the print medium with hills and valleys in the print zone. At least one shape control mechanism transforms each of the hills in the print zone into a corresponding valley in an output path adjacent to the print zone and transforms each of the valleys in the print zone into a corresponding hill in the output path.
