A liquid ejecting apparatus includes an ejecting head that ejects a liquid containing a humectant and water from a nozzle, a cap configured to form a closed space to which the nozzle opens, and a controller that controls the ejecting head, wherein the controller includes a calculation unit and a discharge controller, wherein the calculation unit calculates an available water amount of the liquid in the cap, and when the available water amount is smaller than a preset initial available water amount, the discharge controller discharges an amount of the liquid, where the amount includes, as the available water amount, an amount obtained by multiplying a difference between the available water amount and the initial available water amount by a predetermined coefficient larger than one.

A transportation portion includes an apparatus body, a cover, first and second path formation portions, and a movement portion. The apparatus body has a transportation path including a downward path and an upward path having portions located at the same level in the Z direction. The cover covers and uncovers the transportation path. The first path formation portion is movable to a first position and to a second position. The second path formation portion defines the upward path and defines the downward path with the first path formation portion. The movement portion moves the first path formation portion in response to opening or closing of the cover. The first path formation portion is positioned in a movement area during a closed state. The movement portion moves the first path formation portion to the second position when the cover is opened and to the first position when the cover is closed.

A recording apparatus includes a recording head having discharge ports for discharging a liquid, a cap configured to cap the discharge ports, a switching unit configured to switch between a communication state where an inside of the cap communicates with the atmosphere and a non-communication state where the inside of the cap does not communicate with the atmosphere, and a depressurization unit configured to depressurize the inside of the cap. After driving of the depressurization unit is started while the cap is at a capping position for capping the discharge ports and is in the non-communication state, the switching unit switches the cap to the communication state and then the driving of the depressurization unit is stopped. Idle suction is performed by driving the depressurization unit while the cap is at the capping position and is in the communication state.

An ink absorber includes: a plurality of ink absorbent bodies that are elongated and absorb waste liquid of an ink ejected from a liquid ejecting head; and an accommodating container that accommodates the plurality of ink absorbent bodies, in which the plurality of ink absorbent bodies are arranged such that a longitudinal direction thereof extends vertically. Occupancy of the plurality of ink absorbent bodies in a region in which the ink absorbent bodies are arranged in the accommodating container is desirably 50% or more and 99% or less when the ink absorbent bodies are dry.

A linear motion extensible device (21) includes: rod-shaped members (31); and a rotating plate (42) rotating in a wind-up direction to wind up the rod-shaped members (30) while rotating them around a coupling rotational shaft (32) and rotating in a wind-off direction to push out the rod-shaped members (31) so as to arrange them in a line, wherein the rod-shaped member (31) has: an intermediate shaft (33) and an angle regulating part (34) which regulates widening an angle between the adjacent rod-shaped members (31), the rotating plate (42) has engagement grooves (44) engaged with the coupling rotational shaft (32) and the intermediate shaft (33), and when the rotating plate (42) is rotated in the wind-off direction, the coupling rotational shaft (32) and the intermediate shaft (33) come into contact with an inner surface (45) of the engagement groove (44), are pushed out, and leave the engagement grooves (44).

The printer includes a transport unit having a support surface for supporting a medium, a line head recording on the medium by ejecting ink from a nozzle provided on an ejecting surface thereof, a head moving portion for moving the line head along a moving direction with respect to the transport unit, and a first maintenance unit movably provided in a first direction for covering the ejecting surface. The moving direction intersects a horizontal plane at an angle of 45 degrees or less, the first direction intersects the horizontal plane at an angle of 45 degrees or more and less than 90 degrees, and a movement amount of the first maintenance unit in the first direction is equal to or larger than a movement amount of the line head in the moving direction when the printer is installed on a horizontal plane.

A digital printing device, comprising a nozzle plates' cleaning bar (9) equipped with a plurality of cleaning heads (22) supported in a floating manner by a bar body (23), so as to adapt their own height to the one of an overlying printing module comprising a specific nozzle plate corresponding to the cleaning head (22).

A liquid discharge head according to an embodiment includes a head body having a first surface configured to discharge a liquid and a second surface facing the first surface, a drive IC configured to drive the head body, and a head cover configured to cover at least the second surface of the head body while housing the drive IC. The head cover includes a top plate facing the second surface of the head body and a first side plate that is connected to the top plate and that is in contact with the drive IC, and in the head cover, a thickness of the first side plate is thinner than a thickness of the top plate.

In a method for controlling a liquid ejection apparatus including a liquid ejection head that ejects a plurality of types of liquids through a plurality of nozzles, a cap configured to form a closed space in which the nozzles open, and a cleaning unit configured to perform cleaning that causes liquid to be discharged from the nozzles to the cap and causes liquid to be discharged outside from the cap, cleaning is performed based on a result of correcting a relationship between a change in water evaporation rate and a change in viscosity of each type of liquid by using the amount of water contained in each type of liquid before water evaporation, a humectant substance amount in each type of liquid, an amount of water contained in a mixed liquid, which is a mixture of the types of liquids, before water evaporation, and a humectant substance amount in the mixed liquid.

An object of the present invention is to bring a print head into a liquid ejectable state while reducing waste ink. The present invention is a printing apparatus including: a tank in which liquid is stored; a print head that comprises an ejection port surface on which an ejection port is formed, the ejection port ejecting the liquid which is supplied from the tank; a cap mechanism that caps the ejection port surface of the print head; a timer that counts a time during which the ejection port surface is capped; and a circulation unit configured to circulate the liquid in a circulation path including the tank and the print head, and in a case where the timer counts a predetermined time, the circulation unit circulates the liquid.
