Abstract: Printing apparatuses include (among other components) a photoreceptor (that is adapted to contact and transfer marking material to a printing side of sheets of media), a transport belt adjacent the photoreceptor, a baffle, and an air outlet. The sheets of media are moved by the photoreceptor across a gap to the transport belt in a “processing direction.” The baffle is adjacent the back side of the sheets of media (the side that is opposite to the printing side of the sheets of media). The air outlet is also positioned adjacent the back side of the sheets of media, and the air outlet is adapted to direct a stream of air along the baffle and between the baffle and the back side of the sheets of media to lift the sheets of media off the photoreceptor without damaging the sheets of media or disturbing the unfused marking material thereon.

Abstract: A cap is positioned to contact a printhead when the printhead is not ejecting liquid ink. The cap and the printhead create a sealed space adjacent printhead nozzles when contacting each other. A flexible blade is positioned to contact the printhead when the printhead is not in contact with the cap. The flexible blade is adapted to fold over to spread a liquid solution on the nozzles in a first direction, and the flexible blade is adapted to remove excess amounts of the liquid solution from the nozzles in a second direction. A humidifier is connected to the cap and adapted to supply a moisture form of the liquid solution to the sealed space. A moisture sensor is connected to the cap. The humidifier is adapted to vary supply of the moisture to the sealed space based on the amount of moisture detected by the moisture sensor.

Abstract: Devices include one or more inkjet printheads, a reusable jetting sheet that is adjacent to nozzles of the printheads, support structures (e.g., drive rollers) contacting the sheet, and a cleaning station contacting the sheet. The reusable jetting sheet includes an opening, that is at least as large as the sets of nozzles, and a jetting area spaced from the opening. The support structures are adapted to move the reusable jetting sheet relative to the sets of nozzles. The inkjet printheads are adapted to eject ink from at least some of the nozzles, through the opening, to print media when the opening is positioned adjacent to the sets of nozzles, to print on print media. The inkjet printhead is further adapted to eject ink from at least some of the nozzles to the jetting area when the jetting area is positioned adjacent to the sets of nozzles to perform maintenance jetting.

Abstract: A maintenance cart is configured so the maintenance units within the cart can be selectively moved to correspond to a scalable printhead array. The maintenance cart includes a body configured to selectively move along a path to the printhead array, the body having a recess; and a plurality of cleaning modules mounted within the recess, the plurality of cleaning modules being adjustably arranged within the recess to correspond to a plurality of printheads of the printhead array to enable each cleaning module in the plurality of cleaning modules to align with a corresponding printhead of the printhead array in response to the body being moved to the printhead array.

Abstract: A printing apparatus includes a printhead module having an ink leakage detector to detect a leaked phase change ink. The ink leakage detector includes a plurality of resistance temperature detectors or resistive thermal devices to detect the leaked phase change ink. A horizontally mounted overdriven thermistor can also be used to detect leaked ink.
