Abstract: A method of filling a print head includes drawing a vapor into an empty print head to displace any air in the print head and filling the print head with ink. A method of filling a print head includes connecting a print head to a vacuum pump using a first valve, to a liquid supply using a second valve, and to an ink supply using a third valve, opening the first and second valves, applying vacuum to the print head and liquid supply using the vacuum pump, causing the liquid to generate a vapor that moves into the print head, closing the first valve and the second valve, and opening the third valve to move ink into the print head.

Abstract: An imaging device includes at least one printhead including an aperture plate defining a plurality of apertures, an ink plate and a controller. The at least one printhead is configured to eject liquid ink through the plurality of apertures of the aperture plate. The ink plate is positioned with reference to the aperture plate to enable an ink layer to form between the ink plate and the aperture plate by ink ejected by the printhead. The controller operatively connected to the printhead and configured to operate the printhead to eject the liquid ink to the ink plate to form the link layer.

Abstract: An inkjet printhead including an inkjet configured to eject drops of ink in response to receiving an electrical signal, a memory configured to store image data, and a processor operatively coupled to the inkjet and the memory. The processor receives the image data and determines a period of latency of the inkjet printhead. When the period of latency is within a predetermined timeframe, the processor increases a voltage of the electrical signal to a second voltage for an initial number of drops to eject the drops of ink in a pattern of printed ink drops with reference to at least a portion of the image data and reduce the voltage of the electrical signal after the initial number of drops to eject drops of ink in a pattern of printed ink drops with reference to a remaining portion of the image data, and generates the electrical signal.

Abstract: A media feeder including a tray arranged to hold media, a motor arranged to move the tray in a first direction and a second direction opposite the first direction, a sensor arranged to detect at least one position of the tray, a processor arranged to execute a set of steps, and a memory element arranged to store the set of steps. The set of steps includes: receiving a first input from a user selecting a first loading preference; moving the tray with the motor in the first direction a first distance from the first position to a second position; loading a first quantity of media into the tray; and, moving the tray in the second direction until a first sheet of the first quantity of media is in a feeding position.

Abstract: A direct-to-object printer includes an object rotating subsystem. The object rotating subsystem includes an actuator with an output shaft, a holder mounted to the output shaft, the holder being configured to grip a portion of the object, and a controller operatively connected to the actuator. The controller is configured to operate the actuator to rotate the holder and the object gripped by the holder to enable at least one of the printheads in a printer to print a portion of a circumference of the object that is longer than a width of the at least one printhead.
