  • Publication number: 20180295257
    Abstract: In one example in accordance with the present disclosure a printer cartridge and memory device containing a representation of a compressed multi-dimensional color table is described. The color table includes at least one low dimensional portion of the multi-dimensional color table storing color transformation information at a first resolution and a number of remaining portions of the multi-dimensional color table storing color transformation information at a second resolution. In the color table, the first resolution is greater than the second resolution and the at least one compressed multi-dimensional color table is to generate a high resolution uncompressed multi-dimensional color table the high resolution being at least as great as the first resolution.

  • Publication number: 20180295719
    Abstract: In one implementation, a printed circuit board (PCB) includes a plurality of pads that form a pad pattern on the PCB. In that implementation, the plurality of pads include a group of load pads, a dummy pad, and a false pad. The group of load pads act as contact points to establish an electrical path between a first circuitry and a second circuitry. The dummy pad is coupled to a via that floats electrically and the false pad is coupled to a third circuitry.

  • Publication number: 20180295251
    Abstract: In one example in accordance with the present disclosure system for cleaning a scanning module is described. The system includes a cleaning device to remove debris from a scanning surface of the scanning module and a moving device. The moving device moves the scanning module into a position away from a substrate support surface and extends a cleaning device into a scan path between the scanning surface and the substrate support surface, and rotates to oscillate the cleaning device.

  • Publication number: 20180290465
    Abstract: In an example implementation, a device for sensing media and a media tray includes a sensor to transmit light toward a media tray port, and to generate current from light received at the sensor. The device also includes a circuit to convert the current into a voltage signal to be compared with a threshold for determining one of a media present condition, a media empty condition, and a media tray absent condition.
