A liquid ejecting apparatus includes a liquid ejecting head that has an ejection surface including a first nozzle row configured to eject a first ink and a second nozzle row configured to eject a second ink. The liquid ejecting head is configured to be held in a first posture in which the ejection surface is inclined with respect to a horizontal plane. A dynamic surface tension of the second ink is higher than a dynamic surface tension of the first ink. In the first posture, the first nozzle row is positioned above the second nozzle row with respect to a gravity direction.

A recording device includes a recording head configured to discharge ink onto a recording medium to perform recording, a carriage mounted with the recording head, and configured to perform scanning, a liquid receiving portion disposed so as to face the recording head, so that the recording head discards the ink into the liquid receiving portion, a distance sensor configured to measure a position of a top portion in a vertical direction of a deposit formed by the ink deposited in the liquid receiving portion, and a control unit configured to determine, based on a result of the measurement by the distance sensor, whether the deposit in the liquid receiving portion needs to be removed.

A liquid droplet discharging apparatus includes: a discharging head having: a liquid channel including a nozzle; and an energy applying part which applies, to liquid inside the liquid channel, discharge energy for discharging a liquid droplet from the nozzle; a signal outputting circuit which outputs signals depending on whether the nozzle satisfies a predetermined discharging performance; and a controller. The controller determines whether the nozzle satisfies the predetermined discharging performance, and estimates viscosity of the liquid inside the discharging head based on: viscosity estimation data in which discharge energy information and viscosity information are associated with each other, and a result of the determination performed in a case that the controller controls the energy applying part based on the discharge energy information and that the discharge energy is thereby applied to the liquid inside the liquid channel.

A liquid ejection apparatus includes a controller configured to perform: causing a voltage application circuit to apply a voltage between a liquid ejection head having a plurality of nozzles and an electrode; driving the liquid ejection head for causing a certain nozzle to eject liquid toward a cap in a state where the plurality of nozzles face the cap; receiving a signal from a signal output circuit; determining, based on the received signal, whether the certain nozzle has ejected liquid normally; determining, based on the received signal, whether a leakage current has occurred between the certain nozzle and the electrode; and specifying the certain nozzle as a leakage nozzle if the leakage current has occurred between the certain nozzle and the electrode.

Provided are an inkjet printing apparatus and a recovery method capable of suppressing ink thickening in the ejection openings in the suction process for the ejection openings. A vacuum wiper is moved being in contact with the ejection opening surface of the print head to perform a vacuum wiping process for the arrayed ejection openings sequentially. Ink is circulated in flow paths including the flow paths communicating with the ejection openings for which the vacuum wiping process has been finished.

A printing system includes a controller. The controller is configured to: receive first condition information related to an ejection failure in a printer; determine a maintenance manner applicable to the first condition information; cause the printer to perform a maintenance in the determined maintenance manner; receive second condition information related to the ejection failure in the printer after the maintenance is performed; determine whether an ejection performance in the printer has been improved based on the second condition information in response to performing the maintenance; update an evaluation index in accordance with determination of whether the ejection performance in the printer has been improved, the evaluation index corresponding to the determined maintenance manner.

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.

An inkjet printing apparatus includes a head, a platen, a platen absorbent that temporarily stores ink ejected from the head, a waste ink storage container that stores the ink discharged from the platen absorbent, and an estimation unit that, in a case where the platen is divided into a plurality of regions in a direction intersecting a conveyance direction of the printing medium, estimates an amount of ink stored in the waste ink storage container based on a position of a region to which the ink is ejected by the head and an amount of ink ejected to the region.

An ink jet recording apparatus includes a cap, a control unit, and a recording unit having nozzle arrays each including a plurality of nozzles for ejecting ink in an image recording operation. The cap receives ink preliminarily ejected from the recording unit. The control unit controls an ejection operation to eject ink in response to receiving a recording command to cause an amount of ink ejected from a first nozzle group in a first preliminary ejection executed prior to the recording operation of the image to be smaller than an amount of ink ejected from a second nozzle group different from the first nozzle group in a second preliminary ejection executed prior to the recording operation of the image in a case where the recording command includes an instruction for recording the image by using the second nozzle group without using the first nozzle group among the plurality of nozzles.
