A recording apparatus includes a recording unit, a scanning unit configured to perform relative scanning by moving the recording unit and a recording medium relative to each other at least once with respect to a unit region on the recording medium, a recovery unit configured to perform a recovery operation for maintaining or recovering a recording performance of the recording unit for application of a recording material, and a control unit configured to control the recovery unit, wherein the control unit acquires recording mode information about recording of an image to be performed on a recording medium for (n+1)-th page (n being a natural number) and determines, based on the acquired recording mode information, whether to perform an inter-page recovery operation at timing after recording of an image on a recording medium for n-th page ends and before recording of an image on a recording medium for (n+1)-th page starts.

Recording apparatus, control method, and storage medium

An object is to provide a technique of calculating an ejection amount of an ink in accordance with a printing head. A printing apparatus includes: a printing head including an ejection port array in which multiple ejection ports to eject an ink are arrayed; a conveyer unit configured to convey a printing medium in a conveyance direction; and a controller unit configured to control the printing head. The controller unit executes processing to obtain the printing dot number based on printing data and processing to calculate an amount of the ink used in a case of performing printing based on the printing data by using different calculation methods between a case where a first printing mode is set and a case where a second printing mode is set based on the printing dot number and an ejection amount conversion factor corresponding to a temperature of the printing head.

Printing apparatus and method of controlling printing apparatus

An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Inkjet printing apparatus and inkjet printing method

The object of the present disclosure is to optimize the time necessary for filling and the ink consumption. One embodiment of the present disclosure is a printing apparatus having: a storage unit; a print head having an ejection port from which ink supplied from the storage unit is ejected; an ink supply path that connects the storage unit and the print head; a suction unit configured to perform suction at the ejection port; and a supply control unit configured to supply ink stored in the storage unit to the ink supply path and the print head by performing suction at the ejection port by the suction unit, and the printing apparatus has an acquisition unit configured to acquire information relating to ink discharge from the ink supply path and the supply control unit determines the number of times of suction by the suction unit based on the information.

Printing apparatus, control method thereof and storage medium

To provide a liquid storage container equipped with a plug member that can prevent leakage of a liquid from the liquid storage container and can be opened without causing scatter of the liquid, and a liquid ejection apparatus equipped with the liquid storage container. For the purpose, at least one of a connection part of the convex part with the cover part and an apical part of the convex part most apart from the connection part is provided offset from the centroid of the cover part, seen from a direction orthogonal to an opening surface of a supply port in a state that the plug member is mounted on a supply port of the liquid storage container.

Liquid storage container and liquid ejection apparatus

An ejection apparatus includes a platen for supporting a recording medium, an absorber provided in the platen for absorbing liquid, an ejection unit for ejecting a plurality of types of ink including a first liquid containing a component to be deposited when the first liquid is ejected onto the absorber, and a second liquid different from the first liquid for suppressing deposition of the first liquid, a detection unit for detecting a state of a predetermined region of the absorber, and a control unit for controlling the detection unit to detect the state, and controlling the ejection unit to eject the second liquid to the predetermined region based on a result of the detection. When the first liquid is ejected to the predetermined region, the second liquid is ejected to the predetermined region after the ejection of the first liquid is finished, without using the result of the detection.

Ejection apparatus and deposition suppression method

A recording apparatus discharges an ink in a first color to a position at which an accumulated state on an ink absorber is to be detected. After that, a light is emitted onto the position from a light emitting unit, and reflected light is received by a light receiving unit.

Recording apparatus and method in recording apparatus

According to an embodiment of this invention, an apparatus comprises: a detachable inktank containing ink; a subtank containing the ink supplied from the inktank; a printhead configured to discharge the ink supplied from the subtank; an ink supply path connecting the subtank to the printhead; a valve arranged on the ink supply path; a supply unit configured to supply the ink from the inktank to the subtank by repeatedly opening and closing the valve; a suction unit configured to suck the ink from the printhead; and a control unit configured to control, when the inktank is attached, the supply unit to operate for a predetermined number of times to supply the ink from the inktank to the subtank, and to subsequently control the suction unit to operate to supply the ink from the subtank to the printhead.

Inkjet printing apparatus and ink filling method

An ink jet recording apparatus of a line-recording-head type includes one or more recording heads using the same ink and performs recording of an image by conveying a recording medium using multiple passes through a recording region of the recording head while the recording medium is repeatedly conveyed backward and forward to speed up recording and improve image quality. A recording head is controlled to provide that an amount of ink applied to a recording medium in a case where the recording medium is conveyed at a first speed is smaller than an amount of ink applied to the recording medium in a case where the recording medium is conveyed at a second speed higher than the first speed in both of a case where the recording medium is accelerated and a case where the recording medium is decelerated.

Ink jet recording apparatus

A liquid container unit includes: a liquid container including: a plurality of liquid storage portions; and a plurality of injection ports which are provided to the respective plurality of liquid storage portions, and are configured to enable injection of liquid into the plurality of liquid storage portions; and an injection port cover which is provided to the liquid container so as to be rotatable and is configured to cover the plurality of injection ports so as to be openable and closable, the injection port cover including a plurality of stopper members configured to close the plurality of injection ports when the injection port cover is closed.

Liquid container unit and recording apparatus

An inkjet recording apparatus according to the present disclosure executes a first wiping operation in a case where the count value counted by the count unit is higher than a first threshold value while the recording operation is being performed and execute a second wiping operation when the recording operation completes in a case where the count value counted by the count unit is higher than a second threshold value. The inkjet recording apparatus also executes the second wiping operation when the first wiping operation has been performed while the recording operation is being performed.
