Abstract: A liquid cartridge includes a liquid chamber with a liquid outlet configured to supply the liquid from an interior of the chamber to an exterior of the liquid chamber. A body is positioned in the chamber and is movable between a first position wherein movement of the body is restricted, and a second position wherein the body is movable along a movement path between the first and second positions. The body has a plurality of sides. A detector is positioned in the chamber and is movable in response to movement of the body between the first and second positions. The body defines a plurality openings that extend into the body through at least two sides of the body.

Abstract: A capping mechanism, which causes an ejection space opposing ejection openings of a liquid ejection head to take either one of a sealed state and a non-sealed state, includes an annular component which surrounds the ejection space in the sealed state and an opposing member which opposes the ejection openings with the ejection space interposed therebetween. A mechanism for supplying humidified air generates humidified air and includes a supply opening and a discharging opening. The supply opening and the discharging opening are positioned to form a humidifying passage such that the humidified air having flown along an inner circumferential surface of a first region of the annular component passes through a gap between the ejection openings and the opposing member and flows along an inner circumferential surface of a second region of the annular component, which opposes the first region.

Abstract: An image recording apparatus includes a liquid applying mechanism that applies a first liquid onto a recording medium, a liquid discharge head that discharges a second liquid onto the recording medium, a wiper that wipes a liquid discharge surface of the liquid discharge head, and a processor. The processor counts a number of jams of the recording medium and a number of passages of the recording medium through the liquid discharge head. The processor increments the number of jams when the number of passages is equal to or greater than a first threshold value. The image recording apparatus performs a head recovery operation when a jam of a recording medium occurs and when the number of jams is incremented.

Abstract: When a jam detector detects jamming, forced discharging from a head and wiping of an ejection surface are performed after a recording medium jammed is removed from a conveyor. When the count on a jam counter matches with any of one or more thresholds, at least the number of times the wiping is executed after the jammed recording medium is removed from the conveyor is greater than that executed when the count on the jam counter does not match with any of one or more thresholds.
