Abstract: According to aspects of the embodiments, there is provided a method of measuring the amount of fountain solution using a hot wire anemometer. Fountain solution thickness is measured using the flow rate of vaporized fountain solution and comparing to baseline air only flow rate. The vaporized measurement is correlated with the baseline utilizing specific heat, density and enthalpy values and keeping velocity of fluid constant. Changes in the measurement will then be related to the specific heat, density and enthalpy. Density can be back calculated to yield volume and knowing the area of the image being printed give a real time thickness value.

Abstract: Examples of the preferred embodiments use an ink quantity metric (e.g., lightness L*, darkness, image density, line width) of printed content to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor (e.g., spectrometer) may measure the ink quantity metric of the current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.

Abstract: A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes tracking a machine state of the MFD, predicting a potential defect based on a determination that the machine state is associated with a defect class of a plurality of different defect classes, determining a maintenance routine associated with the defect class, and executing the maintenance routine to prevent the potential defect.

Abstract: An MFD is disclosed. For example, the MFD includes a color printhead to dispense color printing fluid, an enhancement printhead to dispense a three-dimensional (3D) print material, a processor and a non-transitory computer-readable medium storing a plurality of instructions. The instructions when executed by the processor cause the processor to perform operations that include printing a two-dimensional (2D) image on a substrate and printing a 3D object on the 2D image printed on the substrate such that colors of the 2D image provide a desired color for a desired portion of the 3D object.

Abstract: A system dynamically balances a rotating body. The system includes a support that holds the body as it rotates. At least one sensor generates signals indicative of a balance of the body as it rotates and a controller identifies a position on the body where material can be placed to balance the body. The controller operates at least one actuator to move a plurality of ejectors opposite the identified position where the controller operates at least one ejector in the plurality of ejectors to eject material onto the identified position. The system can operate iteratively until the body is balanced within a predetermined range.

Abstract: The present disclosure discloses methods and systems for removing dross from a liquid metal chamber, such as would be used in magnetohydrodynamic (MHD) or metal 3D printing. The method and systems comprise inserting a dross removal tool into a liquid metal chamber. A seal is compromised, fluidically connecting an evacuated volume and the liquid metal chamber. Pressure equalizes between the fluidically coupled volumes through an inflow of gas, liquid, and solid components from the liquid metal chamber into the dross removal tool. The dross removal tool is removed from the liquid metal chamber.
