Provided is a technique which, if external supply of electric power to a printing apparatus that can be driven with electric power stored therein stops, can reduce the effect of the stoppage on printing at the next activation. The printing apparatus includes: a connection unit configured to connect to an external power source; an electric power storage unit configured to store electric power supplied from the external power source through the connection unit; a printing unit configured to perform printing by ejecting an ink onto a print medium conveyed by a conveyance unit; a recovery unit configured to perform a recovery operation of maintaining or restoring an ink ejection characteristic of the printing unit; and a control unit configured to execute the recovery operation according to an amount of electric power stored in the electric power storage unit after the supply of electric power from the external power source stops.

An ink jet recording apparatus includes a head unit, a cap unit, a wipe unit, a cover, an engagement member, a first cam, a second cam, a lifting mechanism, and a sliding mechanism. In the first state, the first cam moves the engagement member downward to the predetermined height or below and the second cam brings the cover into contact with the wipe unit, in the second state, the first cam moves the engagement member downward to the predetermined height or below and the second cam moves the cover upward to a height higher than the first state, and in the third state, the first cam moves the engagement member upward to the predetermined height or above and the second cam moves the cover upward to a height higher than the first state.

A liquid ejection device includes a liquid ejection head, a standby portion, a hold portion, and an operation portion. The liquid ejection head includes a nozzle surface. The standby portion supports a wiping cartridge. The hold portion holds the wiping cartridge. The operation portion moves the hold portion relatively to the standby portion and the liquid ejection head from a position at which the hold portion holds the wiping cartridge that is not held by the hold portion and that is supported by the standby portion to a position at which the wiping cartridge held by the hold portion comes into contact with the nozzle surface.

An inkjet recording apparatus includes an ink collection tray and a cleaning liquid feeding mechanism. When recovery operation for a recording head that ejects ink onto a recording medium is performed, the ink collection tray is disposed opposite the recording head to collect ink pushed out onto the ink ejection surface of the recording head. The cleaning liquid feeding mechanism feeds a cleaning liquid for flushing off the ink onto the ink collection tray. The ink collection tray has a waste ink catching portion disposed opposite the ink ejection surface and a waste ink discharge portion disposed adjacent to the waste ink catching portion, and has a downward slope from the waste ink catching portion toward the waste ink discharge portion. The waste ink catching portion has formed in it a plurality of grooves with a V-shaped cross section extending along the downward slope.

A liquid ejection apparatus includes: a liquid ejection head including an ejection port configured to eject a liquid and a pressure chamber communicating with the ejection port; a circulation unit configured to circulate the liquid in the liquid ejection head so as to pass through the; a recovery unit configured to perform a recovery operation of the liquid ejection head at a circulation flow velocity slower than a circulation flow velocity of the circulation unit in a case where the liquid ejection head prints an image on a printing medium; and a control unit configured to control preliminary ejection to eject the liquid that is not used for the printing from the ejection port in parallel with the recovery operation by the recovery unit.

A print apparatus is disclosed. The print apparatus comprises a print fluid application unit having a plurality of nozzles through which print fluid is to be deposited onto a printable medium during a printing operation. The print apparatus also comprises a nozzle cleaning surface to engage nozzles during a nozzle cleaning operation. The print apparatus also comprises a scanning unit and a controller. The controller is to control the print fluid application unit to deposit print fluid from nozzles of the plurality of nozzles according to an intended pattern onto the nozzle cleaning surface; control the scanning unit to scan the pattern formed on the nozzle cleaning surface; and responsive to determining, based on the scan, that print fluid from a nozzle of the plurality of nozzles has not been deposited according to the intended pattern, generate an instruction signal regarding maintenance of the print fluid application unit. A method and a machine-readable medium are also disclosed.

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.

A printing device includes a print unit configured to, in a printing operation, apply a predetermined pattern of fluid onto a recording medium, the print unit including a plurality of nozzles. The printing device includes a purge tray, the purge tray being configured to, in a purging operation, collect fluid purged from the print unit, and a recording medium transport unit configured to transport the recording medium in a transport direction. The print unit has a length extending in a printing range direction, the printing range direction being perpendicular to the transport direction. The purge tray has a length extending in the printing range direction, the length of the purge tray being smaller than the length of the print unit. The purge tray is configured to, in the purging operation, move underneath the print unit in the printing range direction.

A printing apparatus includes a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets; a recovery unit that recovers an ejecting condition of nozzles of the printing head; and a control unit that determines whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controls a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.
