A wiping device includes a wiper unit, a carriage, and a fixing member. The wiper unit includes a wiper that wipes a liquid discharge surface of a liquid discharge head from which liquid is to be discharged. The carriage moves along the liquid discharge surface in a first direction and a second direction, both of which are opposite to each other. The fixing member fixes the wiper unit to the carriage. When the carriage is disposed on a side in the first direction with respect to a middle point in a moving range of the carriage, the fixing member is removable in the first direction.

A printing apparatus includes a line head, a wiper unit, and a guide. The line head is configured to eject ink from an ejection surface extending in an A direction. The wiper unit includes a wiping portion configured to wipe the ink and a liquid container configured to hold the wiped ink. The wiper unit is configured to move in a Y direction and clean the ejection surface with the wiping portion. The guide extends in the Y direction and guides the wiper unit. The wiper unit includes a guided portion configured to be guided by the guide. The ink container and the guided portion form an overlap in the A direction when viewed in the Y direction.

A printer, which is an example of a liquid ejecting apparatus, includes a movable body including a head for ejecting a liquid or a cap performing maintenance of the head. Further, the printer includes a pair of rack and pinion mechanisms including a rack and a drive gear to move the movable body in a first direction in which the rack extends; and a switching mechanism provided for each of the rack and pinion mechanisms and switching presence and absence of meshing between the rack and the drive gear when the movable body is at an exchange position.

An inkjet recording apparatus includes a recording head having a plurality of nozzles for ejecting ink, an endless conveying belt conveying a recording medium and having a plurality of openings through which ink is passed when the recording head performs flushing, a reading sensor for reading, in a first reading mode, information on openings in the conveying belt and, in a second reading mode, information on the recording medium on the conveying belt, an ejection control portion for controlling ejection of the ink from the recording head based on at least one of the information on the openings and the information on the recording medium, and a reading mode switching control portion for switching the reading mode of the reading sensor between the first and second reading modes.

A control unit in an inkjet recording device controls a drive roller to stop a conveyance belt such that, after completion of a print job, a reference specifying portion of the conveyance belt is stopped at a position on an upstream side in a conveyance direction of the conveyance belt from a detecting position of a reference detection sensor by a particular distance or longer. The particular distance is a distance, for which the conveyance belt moves until the conveyance belt reaches a specific conveyance speed after the conveyance belt in a stopped state starts moving by driving of the drive roller.

A controller of an inkjet recording apparatus determines whether waste is adhered around the periphery of the openings of the conveyor belt based on the detection result of the surface state detection sensor before and after the recording head executes flushing. Then, and based on the presence or absence of waste and a previously set placement pattern of the recording medium to be supplied onto the conveyor belt, in the cycle following the cycle in which the flushing was executed, the controller causes the supply of the recording medium onto the conveyor belt by the recording medium supply mechanism to execute or stop in the following cycle.

An inkjet recording apparatus includes a recording head, a housing, a cap unit, a protrusion and a guide part. The recording head has an ink ejecting port on a lower face. The housing supports the recording head. The cap unit includes a cap. The cap unit is inserted into a space below the recording head in a predetermined direction to be attached to the housing and to cover the lower face of the recording head with the cap. The protrusion is protruded from a lower portion of the housing on a rear side in the predetermined direction more downward than the lower face of the recording head. The guide part is formed in an upper portion of the cap unit on the rear side in the predetermined direction and comes into contact with the protrusion so as to guide insertion and removal of the cap unit.

The controller of an inkjet recording apparatus supplies a recording medium onto the conveyor belt with a pair of registration rollers based on a detection result of the trailing edge of the recording medium by a first detection sensor and a detection result of an opening by a second detection sensor. The controller determines whether the recording medium is being placed on the conveyor belt coinciding with the opening that is moved due to the traveling of the conveyor belt, and based on the determination result, the controller controls the recording head to execute flushing and the pair of registration rollers to supply a subsequent recording medium onto the conveyor belt.

A wiper that extends toward an inkjet head and wipes a nozzle surface of the inkjet head includes: a base section extending in an extension direction of the wiper, an inclined surface continuous with the base section and having, in a direction in which the wiper travels during wiping, a thickness that gradually decreases toward the extension direction; and a leading-end projecting section thinner than the base section and provided at a leading end of the wiper in such a manner as to be continuous with the inclined surface and project in the extension direction.

The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.
