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 liquid ejecting device includes a head, a cap, a moving mechanism and a controller. The moving mechanism is configured to move the head and the cap relative to each other to switch the cap between a capping state in which the cap is in contact with the head and covers the plurality of nozzles and a non-capping state in which the cap is separated from the head and uncovers the same. The controller is configured to perform setting a non-ejection drive time based on an uncapped time duration which is a length of time from a timing at which the cap is switched to the non-capping state until a timing at which the cap is switched back to the capping state. The controller is configured to perform vibrating meniscus of liquid in the plurality of nozzles during the non-ejection drive time.

Disclosed herein is a spittoon assembly for a printing device, a printing device comprising a spittoon assembly, and a method of cleaning a print head using a spittoon assembly. The spittoon assembly comprises a waste receptacle and a spit plate with a receiving surface. The receiving surface is inclined relative to a horizontal direction by an inclination angle when the spittoon assembly is mounted in the printing device. A fluid path extends from the receiving surface to the waste receptacle.

A head cap configured to maintain a head configured to discharge a liquid from nozzles formed in a nozzle surface, the head cap includes a cap configured to cap the nozzle surface of the head, and a holder holding the cap, the holder being detachably attachable to one of a carriage mounting the head and a guide configured to guide the carriage.

A recording apparatus includes a recovery unit including a first cap configured to cap the first ejection port array and a second cap configured to cap the second ejection port array, a first tank configured to contain the first liquid to be supplied to the first ejection port array, a second tank that is arranged farther from the recovery unit than the first tank is to the recovery unit and that is configured to contain the second liquid to be supplied to the second ejection port array, a first atmosphere communication valve, a second atmosphere communication valve, and a control unit configured to, in a case where an instruction to transport the recording apparatus is input, perform control of opening the first atmosphere communication valve, and perform control of closing the second atmosphere communication valve.

An integrated inkjet module includes: a chassis having an elongate base plate and a rear wall extending upwards therefrom; an elongate printhead liftably mounted on the chassis; a lift mechanism operatively connected to the printhead for lifting and lowering the printhead relative to the base plate; a capping assembly slidably mounted on the base plate, the capping assembly having a capper extending parallel with the rear wall and the printhead; a capper movement mechanism operatively connected to the capping assembly for linearly slidably moving the capping assembly towards and away from the rear wall; and a cap cover pivotally mounted to the rear wall. During use, engagement of part of the capping assembly with the cap cover pivots the cap cover away from the capper to allow sliding movement of the capper towards the rear wall and into a covered position.

An ink-jet printer includes: a tank including an ink storage chamber and an inlet; a cap which is detachably attachable to the inlet; a cover configured to move between a first position and a second position farther from the inlet than the first position; and an arm configured to locate the cap at an inlet closing position and an inlet opening position. Under a condition that the cap is in the inlet opening position and the cover is in the second position, the arm holds the cap in a state that the cap does not contact with the cover. Under a condition that the cap is in the inlet opening position, a part of at least one of the cap and the arm is in the moving locus of the cover between the first position and the second position.

The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.

A capping device configured to form a space surrounding an opening of a nozzle by coming into contact with a liquid ejecting head having the nozzle for ejecting a liquid, includes a unit cap, which is an example of a cap, including a recess that forms the space, a humidifying chamber that has an inlet through which a humidifying fluid for humidifying the space flows in and an outlet through which the humidifying fluid flows out, and a first moisture permeable membrane, which is an example of a partition wall, having gas permeability, that partitions the recess and the humidifying chamber. The recess has a discharge hole, which is an example of a hole for discharging the liquid discharged from the liquid ejecting head, which is the example of the cap.

A printing apparatus comprises: a printing unit configured to print onto a sheet by ejecting ink from a printing head; a maintenance unit configured to perform a maintenance operation capable of being performed in parallel with the printing performed by the printing unit; and a control unit configured to control the maintenance unit such that when the printing by the printing unit and the maintenance operation by the maintenance unit are performed in parallel, and the maintenance operation is not completed by the time the printing by the printing unit has ended, the maintenance operation is ended without being completed.
