Printing apparatus and a method of controlling a printing apparatus including a control unit controlling a cleaning operation of a wiping unit wiping an ejection port surface

A printing apparatus including a printing unit configured with an ejection port surface for ejecting ink, a wiping unit configured to wipe the ejection port surface using a wiping member by relative movement with the printing unit, an application unit configured to apply a wiping liquid to the wiping member, a detection unit configured to detect the ink on the wiping member, and a control unit configured to cause the printing unit to print a predetermined pattern on a predetermined area of the wiping member and to cause the application unit to apply the wiping liquid, and, then, to cause the detection unit to detect the ink on the predetermined area.

Printing apparatus and control method

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

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

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 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.

Inkjet recording apparatus

A printing apparatus includes a printing head configured to eject a first ink and a second ink, wherein the second ink generates less deposition than the first ink, an ink absorber configured to absorb the ink ejected from the printing head, a detection unit configured to detect a state of the ink absorber through an optical method, and a control unit configured to cause the printing head to eject the second ink to the ink absorber based on a detection result of the detection unit.

Inkjet printing apparatus

An inkjet recording apparatus includes a recording unit, a first ink storage unit, a second ink storage unit, a discharge unit, a first detection unit configured to detect that an amount of the ink stored in the first ink storage unit is below a first predetermined amount, and a second detection unit configured to detect that an amount of the ink stored in the second ink storage unit is below a second predetermined amount. The inkjet recording apparatus further includes a control unit configured to control the discharge operation after the detection by the first detection unit and the detection by the second detection unit based on a detection timing of the first detection unit and a detection timing of the second detection unit.

Inkjet recording apparatus and ink discharge method

Provided is an inkjet printing apparatus capable of performing preliminary discharge without the influence of mist while suppressing degradation in throughput regardless of a preliminary discharge time. Specifically, an inkjet printing apparatus that performs a wiping operation on a nozzle arrangement surface provided with nozzles discharging an ink in a print head includes a wiping determination unit that determines whether to perform the wiping operation before preliminary discharge based on the amount of the preliminary discharge to be performed.
