Abstract: A positioning device to control the position of a print agent applicator comprises a mount to support a print agent applicator at a load point on the mount; an actuator coupled to the mount to apply a driving force at an actuation point on the mount; and a guide mechanism to guide the mount and supported print agent applicator, under the driving force, to translate along a predetermined path towards a printing drum to form an engaging contact between the print agent applicator and the printing drum.

Abstract: An image formation device includes at least one frame portion supporting at least one emitter to emit airborne charges, at least one radiation element to emit radiation, and a fluid ejection device to deposit droplets of ink particles within a non-aqueous fluid carrier onto a substrate. Upon relative movement between the at least one frame portion and the substrate, the emitted airborne charges are to electrostatically fix, and the at least one radiation element is to emit radiation to cause at least further fixation of, the deposited particles relative to the substrate.

Abstract: In an example, object model data representing at least a portion of an object defining an initial object geometry is received, wherein the object is to be generated by an additive manufacturing apparatus by fusing build material using a radiant heater. Based on a non-uniform radiant heating distribution of the additive manufacturing apparatus, a modified object geometry may be determined, wherein a local modification of the object geometry is determined based on a local radiant heating parameter determined from the non-uniform radiant heating distribution.

Abstract: Generating personalized user interfaces includes receiving an indication of a user device in a proximity of an image forming device. Based on the user device, a system can determine a prediction of intent to use the image forming device by a user account associated with the user device and in response to determining the prediction is greater than a threshold, instructing the image forming device to provide an indicator corresponding to the user account.

Abstract: An example display device includes a panel and a controller to define a boundary between a first region of an input layer of the panel and a second region of the input layer of the panel. The example controller disables digital ink input for the first region when the first region is designated for video output and the controller enables digital ink input for the second region when the second region is designated for receiving digital ink input.

Abstract: A system includes a machine readable storage medium storing instructions and a processor. The processor is to execute instructions to receive contone agent maps of a three-dimensional (3D) part and sensed thermal maps from the 3D printing of the 3D part on a 3D printer. The processor is to execute instructions to generate layer sequences including the contone agent maps and the sensed thermal map for each layer of the 3D part. The processor is to execute instructions to select training samples from the layer sequences having temperature intensity variations within each layer or between neighboring layers. The processor is to execute instructions to train a neural network using the training samples to generate a model to predict thermal behavior in the 3D printer.

Abstract: In an example in accordance with the present disclosure, a method is described. According to the method, boundary values for a setting for a signal between a compute device and a peripheral device are determined. A target value for the setting is determined. The target value is a value between determined boundary values. The setting for the signal is adjusted to match the target value.
