  • Patent number: 11192376
    Abstract: A wiping assembly includes a wiper that wipes a liquid ejection head, a wiper cleaner, and a mover that moves the wiper relative to the wiper cleaner. The wiper cleaner includes a first member, a second member, an absorbent, and a presser. An opening is located in the first member. The second member includes a projecting portion opposed to the opening. The absorbent has a plate shape and is disposed between the first member and the second member. The presser presses the second member toward the first member. The projecting portion presses the absorbent toward the opening. A portion of the absorbent is deformed to form a protruding portion that protrudes in a projection direction of the projecting portion from the opening by pressing by the projecting portion. The mover moves the wiper such that the wiper contacts the protruding portion of the absorbent.
