A control portion sets, as a control period, a period after arrival, at a position opposite a recording head, of a first recording medium until passage, at the position opposite the recording head, of a last recording medium. The control portion sets nozzles that do not face the recording medium during the control period as first nozzles, and nozzles that face the recording medium during the control period as second nozzles, to make the total amount of ink ejected by each of the first nozzles in flashing processing during the control period smaller than the total amount of ink ejected by each of the second nozzles.

A control portion makes a recording head perform flushing processing every time a flushing area that does not overlap a recording medium faces the recording head but makes the recording head perform no flushing processing when a flushing area that at least in a part of it overlaps a recording medium faces the recording head. The longer a non-flashing period between the previous and present sessions of flushing processing, the larger the control portion makes the amount of ink ejected by each of nozzles in the present session of flushing processing.

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 suction unit causes the conveyance belt to suck the sheet. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. 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 ratio of the recessed portions per unit area in a facing region of the conveyance plate facing the head end portion is smaller than a ratio of the recessed portions per unit area in a region other than the facing region.

A liquid ejection device includes a liquid ejection unit configured to perform printing by ejecting a liquid from a nozzle onto a medium, a maintenance unit configured to perform maintenance of the liquid ejection unit, a determination unit configured to determine whether printing data for the printing is ruled-line data including a vertical ruled line or non-ruled-line data not including the vertical ruled line, a storage unit configured to store a determination result obtained by the determination unit, and a control unit. The control unit changes intensity of the maintenance in accordance with a frequency of the ruled-line data included in the determination result stored in the storage unit.

A liquid discharging apparatus, having a head with nozzles, a scanning assembly, a conveyer, and a controller, is provided. The controller is configured to determine whether the nozzles are to be flushed in a moving action which accompanies a discharging action, if the controller determines the nozzles are not to be flushed in the moving action, conduct the moving action to move the head at a first acceleration rate; if the controller determines the nozzles are to be flushed in the moving action, determine whether a distance between a flushing range and a discharging range is greater than or equal to a predetermined distance; and if the controller determines the distance is greater than or equal to the predetermined distance, conduct the moving action to move the head at a second acceleration rate and control the head to discharge liquid for flushing the nozzles.

Provided is an inkjet recording apparatus that performs inkjet recording on a recording medium in a recording region. The inkjet recording apparatus includes a recording head that includes an ejection port surface where an ejection port for ejecting ink is provided, is the recording head being movable within a range including the recording region and a non-recording region where the recording is not performed, a cap capable of letting the ejection port in a capping state in the non-recording region, a blade that is placed between the recording region and the cap in a moving direction of the recording head, the blade being capable of wiping the ejection port of the recording head as the recording head moves from the non-recording region to the recording region, a blade moving unit capable of moving the blade up and down, and a control unit that controls the blade moving unit.

A wiping unit includes a wiping member with a long shape configured to wipe a liquid ejecting head configured to discharge liquid, a first roller around which to wind the wiping member, a second roller configured to wind up the wiping member fed out from the first roller, a driving force transmission mechanism configured to transmit a driving force of a driving source to the second roller, a conveyance roller configured to make contact with the wiping member and rotate along with a movement of the wiping member, a first detection unit configured to detect a rotation amount of the first roller, and a second detection unit configured to detect a rotation amount of the conveyance roller.

There is provided a liquid ejecting apparatus including: a head having a nozzle; a carriage; a receiver; and a controller. The controller is configured to execute: a first flushing processing; a second flushing processing including at least one of a discharge flushing driving and a non-discharge flushing driving of driving; and a printing processing. The first flushing processing is executed in a case that a first count value is not less than a first threshold value, the first count value being an elapsed time since a completion of the first flushing processing. The second flushing processing is executed in a case that a second count value is not less than a second threshold value, the second count value being an elapsed time since a completion of the printing processing.

A printing apparatus includes: a recording head, discharging ink to a recording medium; a roller, having an outer circumferential surface provided for ink idly discharged from the recording head to be attached; a motor, rotating the roller in a predetermined direction; and a scraper, provided to scrape off the ink attached to the outer circumferential surface of the roller in a state in which the roller rotates in the predetermined direction. The scraper has: a recessed surface making surface contact with the outer circumferential surface of the roller; and a notch part formed at an end of the recessed surface, making line contact with the outer circumferential surface of the roller, and recessed in a substantially shape along a rotation direction of the roller and from the end of the recessed surface toward another end.

There is provided a liquid ejection apparatus, including: a head; a signal output circuit; a discharge mechanism; a controller; and a memory in which association information is stored. The controller is configured to: diagnose a degree of defectiveness of the head based on a signal from the signal output circuit; and receive, from a user, an input of discharge amount information. In response to the input of the discharge amount information, the controller is configured to: control the discharge mechanism to discharge a liquid by a discharge amount corresponding to the discharge amount information; and change the association in the association information based on the discharge amount corresponding to the discharge amount information and a discharge amount that corresponds to the degree of the defectiveness of the head.
