Abstract: A fuser includes a pressure roller to rotate and a heating belt to form a fixing nip with the pressure roller. The heating belt comprises at each end of the heating belt a bush to support the heating belt, a fixing flange to rotatably support the bush, and a plurality of springs to elastically connect between the bush and the fixing flange, to rotate the bush about an axis passing through a first surface of the bush and a second surface of the bush opposite to the first surface of the bush.

Abstract: An electrothermal heating device for heating a print medium includes an endless belt, a first electrode and a second electrode. The endless belt rotates in a rotational direction about a rotation axis that defines an axial direction, so as to generate heat when the endless belt rotates and is supplied with power. The endless belt includes a base portion made of a nanocomposite material having a carbon filler. The first and second electrodes are in contact with the base portion of the endless belt. The first and second electrodes extend in the axial direction of the endless belt, and are spaced apart in the rotational direction of the endless belt. A volume resistivity of the base portion of the endless belt in the rotational direction is less than a volume resistivity of the base portion in the axial direction.

Abstract: Example implementations relate to emulating 3D texture patterns in a printer system. One example implementation receives an image having a number of image pixels and selects from a plurality of digital substrates which each correspond to a physical substrate. Each digital substrate has luminance change data corresponding to heights of a 3D texture pattern at respective locations of the physical substrate. An image having emulated 3D texture is generated by adjusting the luminance of the image pixels corresponding to respective locations of the physical substrate and according to the corresponding luminance change data.

Abstract: In some examples, in a component space defined by a plurality of edges, a system defines a first point on a first edge of the plurality of edges, the first point dividing the first edge into a first portion in which a first component is to be used in producing an output by an output device, and a second portion in which the first component is not used in producing an output by the output device, where a first space inside the component space corresponding to the first portion is to use the first component in producing an output by the output device, and a second space inside the component space corresponding to the second portion is to not use the first component in producing an output by the output device. The system generates values of an internal node within the component space by interpolating between a first node on the first edge and a second node on a second edge of the plurality of edges, where the interpolating is along an interpolation axis based on a boundary between the first space and the second space.

Abstract: Executable code causes a processor to segment a first frame to determine a background portion of the first frame, and segment a second frame to determine a background portion of the second frame. The executable code causes the processor to compare the background portion of the first frame to the background portion of the second frame to determine a difference between the first frame and the second frame. The executable code also causes the processor to alter the background portion of the second frame responsive to the difference. The executable code causes the processor to display the altered second frame on a display.

Abstract: A method, according to one example, includes receiving a 360-degree image that was captured by a 360-degree camera, converting the 360-degree image into a rectangular image, and copying an edge portion from a first edge of the rectangular image and pasting the copied edge portion to a second edge of the rectangular image, thereby forming a modified rectangular image. The method further includes applying a neural network to the modified rectangular image to identify objects appearing in the modified rectangular image, wherein the modified rectangular image facilitates object identification near the second edge.
