Wiping assembly for liquid ejection head and ink jet printer
A wiping assembly for a liquid ejection head includes a wiper including a first wiper surface facing in a first direction and a second wiper surface facing in a second direction, a wiper cleaner, a mover, and a controller. A protruding portion of the wiper cleaner includes a first cleaning surface facing in the second direction and a second cleaning surface facing in the first direction. The controller controls the mover to move at least one of the wiper and the wiper cleaner in at least one of the first and second directions from a state in which the wiper is located farther in the second direction than the protruding portion to bring the first wiper surface into contact with the first cleaning surface, and to move the at least one of the wiper and the wiper cleaner in at least one of the first and second directions from a state in which the wiper is located farther in the first direction than the protruding portion to bring the second wiper surface into contact with the second cleaning surface.
1. A wiping assembly for a liquid ejection head, the wiper assembly comprising:
a wiper including a first wiper surface facing in a first direction and a second wiper surface facing in a second direction that is an opposite direction of the first direction to wipe the liquid ejection head;
a wiper cleaner;
a mover to move at least one of the wiper and the wiper cleaner in at least one of the first direction and the second direction; and
a controller configured or programmed to control the mover; wherein
the wiper cleaner includes a protruding portion that protrudes in a moving path of the wiper and includes a first cleaning surface facing in the second direction and a second cleaning surface facing in the first direction;
the controller is configured or programmed to control the mover to move the at least one of the wiper and the wiper cleaner so that one of the at least one of the wiper and the wiper cleaner moves in the first direction relative to the other of the at least one of the wiper and the wiper cleaner from a state in which the wiper is located at a position farther in the second direction than the protruding portion and to bring the first wiper surface into contact with the first cleaning surface, and to move the at least one of the wiper and the wiper cleaner so that one of the at least one of the wiper and the wiper cleaner moves in the second direction relative to the other of the at least one of the wiper and the wiper cleaner from a state in which the wiper is located at a position farther in the first direction than the protruding portion and to bring the second wiper surface into contact with the second cleaning surface;
the first wiper surface and the second wiper surface extend in a width direction perpendicular or substantially perpendicular to the first direction;
the first cleaning surface and the second cleaning surface extend in the width direction;
the protruding portion protrudes in a direction perpendicular or substantially perpendicular to the first direction and the width direction;
the first cleaning surface includes a first fixed inclination in the first direction toward a protruding direction of the protruding portion; and
the second cleaning surface includes a second fixed inclination in the second direction toward the protruding direction of the protruding portion.
2. The wiping assembly according to claim 1 , wherein the protruding portion is made of a material that absorbs a liquid.
3. The wiping assembly according to claim 1 , further comprising:
a position adjuster able to move the at least one of the wiper and the wiper cleaner in a protruding direction of the protruding portion and an opposite direction to the protruding direction.
4. An ink jet printer comprising:
the wiping assembly according to claim 1 ; and
a liquid ejection head to eject an ink.
