Abstract: Examples of a paper-clearance apparatus for removing jammed paper from a printer are described herein. The paper-clearance apparatus includes an outer shaft mounted transversely above a printing medium path of a printer; an inner shaft movably disposed inside the outer shaft; a roller assembly including a sliding bush mounted over the outer shaft; and a handle connected inside the inner shaft from outside a printer housing. The handle is being rotatable so that the roller connected with the inner shaft touches the jammed paper and rotates along with the jammed paper to grip the jammed paper. Further, the handle is being pullable away from the printer housing so as to pull out the jammed paper beneath the printer housing.

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.
