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: Apparatuses include a conveyor moving in a processing direction, a print head positioned adjacent the conveyor, a light source positioned adjacent a first side of the conveyor, a movable mirror positioned adjacent a second side of the conveyor, that is across the conveyor from the first side of the conveyor, a fixed mirror positioned adjacent the first side of the conveyor (the fixed mirror is between the light source and the print head), and a light sensor position adjacent the second side of the conveyor. The light sensor is between the movable mirror and the print head. The light source outputs light to the movable mirror across the conveyor, the movable mirror directs the light back across the conveyor to the fixed mirror, and the fixed mirror directs the light again across the conveyor to the light sensor.
