An image forming apparatus includes a recording head, a cap, a tank, a pump, a third communication pipe and a controller. The cap forms a sealed space including an ejection port of the recording head. The tank is connected to the sealed space through a first communication pipe and generates a humidified air. The pump feeds the humidified air to the sealed space through the first communication pipe. The third communication pipe connects the pump and the sealed space. The controller is performable a capping operation to feed the humidified air to the sealed space and a long-period leaving operation to feed the humidifying liquid in the tank to the sealed space through the third communication pipe and to stop a driving of the pump after a predetermined amount of the humidifying liquid is fed in the sealed space.

An electronic apparatus includes a mobile object, a moving mechanism, and a functional mechanism. The mobile object has a first contact member and performs a moving operation within a drawing area and a set drawing operation on a drawing medium. The moving mechanism moves the mobile object. The functional mechanism has a portion located within the drawing area and takes a standby state and a function exercised state in which a set function is exercised. The functional mechanism includes a movable portion having a second contact member. In an abutting state where the first contact member and the second contact member come into contact with each other outside the drawing area, the mobile object moves along a movable direction of the movable portion so that the movable portion moves to bring the functional mechanism into the function exercised state.

According to the present invention, provided is a system comprising: an acquisition unit configured to acquire log information of a job executed on a device; and a learning unit configured to perform learning for generating, by using the log information of the device acquired by the acquisition unit as learning data, a learned model to be used by the device to estimate necessity of executing a maintenance operation.

A printer includes a line head, a transport unit, a head moving unit, a maintenance unit, a lid unit, and a rotation mechanism portion. The head moving unit moves the line head to a retreat position and a recording position along a B direction. The maintenance unit includes a cap portion configured to cover the nozzles, is formed with an opening, and is movable in a transport direction of a medium. A lid unit is rotatable about a rotation axis, and closes the opening in a closed posture. When the head moving unit moves the line head from the recording position to the retreat position, the rotation mechanism portion rotates the lid unit so that a posture of the lid unit becomes the closed posture.

A print head cap comprising a base element extending along a longitudinal direction and a first wall element extending along the longitudinal direction and connected to the base element. The base element comprises a cleaning element of a cleaning material on an inner side of the base element facing the first wall element. The first wall element comprises a first attachment element to removably attach the print head cap to a print head. The first attachment element allows removing the print head cap from the print head while the cleaning element remains in contact with the printing area of the print head by sliding the print head cap along the longitudinal direction, wherein the longitudinal direction is perpendicular to an ink depositing direction of the print head.

A liquid ejection apparatus includes a plurality of liquid ejection units ejecting different types of liquids. Each liquid ejection unit includes an ejection orifice which ejects a liquid, first and second liquid tanks which store the liquid, and a liquid flow path which connects the first liquid tank and the second liquid tank to each other across the ejection orifice. The liquid ejection apparatus further includes a cap member which covers of the ejection orifices of the plurality of liquid ejection units and forms a space sealed between the ejection orifices of the plurality of liquid ejection units and the cap member, and a pressure control mechanism which simultaneously pressurizes the first and second liquid tanks.

An inkjet device includes a stage, a first suction member, a second suction member, a spray member, and a substrate. The first suction member is at a first side surface of the stage. The second suction member is at a second side surface of the stage. The spray member is configured to store ink and to move above top surfaces of the stage, the first suction member, and the second suction member, the spray member including a body and a nozzle at a side of the body to discharge the ink. The substrate is on the stage in which the ink discharged from the spray member is printed on the substrate.

A liquid ejection apparatus includes a liquid ejection head configured to eject liquid from a plurality of nozzles to a medium and a plurality of caps configured to cover a plurality of nozzle groups. The plurality of caps includes a first cap group covering a first nozzle group positioned near the center of the liquid ejection head among the plurality of nozzle groups and a second cap group and a third cap group provided at positions sandwiching the first cap group in the width direction. The liquid ejection head is configured to execute a first idle ejection for ejecting liquid from the plurality of nozzles constituting the plurality of nozzle groups to the plurality of caps and a second idle ejection for ejecting the liquid from the plurality of nozzles constituting the second nozzle group and the third nozzle group to the second cap group and the third cap group.

There is provided a liquid discharge apparatus. A print head includes a nozzle that discharges a liquid. A recovery unit includes a cap that caps the nozzle and a pump that suctions a liquid from the nozzle via the cap, and discharges to a waste liquid tank that accommodates a waste liquid of suctioned liquid. A control unit causes the recovery unit to execute at least one of a first recovery operation, in which the suction pump is driven at a first driving amount, or a second recovery operation, in which the pump is driven at a second driving amount smaller than the first driving amount, based on an amount of waste liquid discharged to the waste liquid tank.

A liquid discharging apparatus, having a head with a nozzle surface, a reservoir section having a liquid reservoir chamber and a first atmosphere communication path, a liquid flow path connecting the head with the liquid reservoir chamber, a first switching assembly to switch states of the first atmosphere communication path between a connecting state and a disconnecting state, a cap having a body and a second atmosphere communication path, a movable assembly to move the cap between a covering position and a separated position, and a controller, is provided. The controller is configured to control the head to discharge the liquid, and after discharging the liquid from the head, control the movable assembly to move the cap from the separated position to the covering position. With the cap being located at the covering position, the first atmosphere communication path is placed in the connecting state.
