摘要： An ink jet printer includes an ink head with a nozzle surface, a cleaner assembly including a cleaner that contacts the nozzle surface, a conveyor that moves the ink head and the cleaner assembly relative to each other, and a controller. The nozzle surface includes a first end in a first direction, and a second end in a second direction. The controller brings the cleaner into contact with a portion of the nozzle surface ahead of the first end in the second direction, and then moves the cleaner in the second direction while keeping the cleaner in contact with the nozzle surface. Thereafter, the controller moves the cleaner away from the nozzle surface. In addition, the controller brings the cleaner into contact with a portion of the nozzle surface ahead of the second end in the first direction, and then moves the cleaner in the first direction while keeping the cleaner in contact with the nozzle surface.

摘要： A processing device includes a support table to support a sheet medium, a sheet cutter to cut the medium supported on the support table, a cutter holder to move the sheet cutter in a toward-away direction in which the sheet cutter moves toward and away from the support table, and a cutter transporter to move the cutter holder in a cutting direction that is orthogonal to a transport direction of the medium. The cutter holder includes a holder movable in the toward-away direction and that holds the sheet cutter, an actuator including a rod that extends or retracts, a link connected to the rod and the holder, and a rotation shaft that rotatably supports the link so that the holder moves in the toward-away direction in response to extension or retraction of the rod.

摘要： 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.

摘要： A printer includes ink heads, an ink head conveyor, caps, a conveyor, suction pumps, opening passages, suction passages, and cap valves. The suction pumps are each provided for an associated one of the caps. The suction passages each connect an associated one of the caps to an associated one of the suction pumps. The conveyor 50 includes a base, a movable table, a guide wall, and a spring. The movable table supports the caps and includes a table wall extending upward from an end of the movable table facing in a first direction extending to a cap attaching position in a main scanning direction. The cap valves are disposed on a surface of the table wall facing in the first direction.

摘要： A printer includes ink heads, an ink head conveyor, a movable table, cap valves, lifters, a guide device, and a controller. The conveyor moves the ink heads in a main scanning direction. The movable table includes caps and is movable in the main scanning direction by the conveyor. The guide device defines a path along which the movable table is movable between a cap attaching position, a valve opening position, and a retracted position. Movement of the movable table to the valve opening position causes the lifters to abut against the cap valves to bring the cap valves to an open state and expose opening/closing passages to the atmosphere. Movement of the movable table to the cap attaching position from the valve opening position causes the lifters to move away from the cap valves to bring the cap valves to a closed state.

摘要： A printer includes an ink head including a nozzle surface on which a nozzle is provided, a wiper extending upward to wipe the nozzle surface, a wiper mover to move the wiper in a sub-scanning direction, a wiper cleaner disposed downstream of a carriage and extending downward to remove ink adhering to the wiper, and a controller configured or programmed to control the wiper mover. The controller is configured or programmed to control the wiper mover such that the nozzle surface is wiped by the wiper after bringing the wiper into contact with the wiper cleaner or to bring the wiper into contact with the wiper cleaner after wiping the nozzle surface by the wiper.

摘要： 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.
