According to an embodiment of the present invention, a printing apparatus that satisfactorily sucks and recovers a printhead is provided. A printing apparatus that includes a transfer member, and the first and second printheads has the following arrangement. The apparatus includes the first and second suction units which suck a plurality of nozzles of the first and second printheads, a common negative-pressure generation unit which generates a negative-pressure for suction by these suction units, and a moving unit which moves these suction units from one end to the other end of each printhead. Then, the moving unit moves the first and second suction units so as to pass through concave gaps with respect to ink discharge surfaces of the first and second printheads corresponding to the first and second suction units at different timings.

A liquid droplet ejecting apparatus includes a liquid droplet ejecting head that includes a plurality of nozzles from which a liquid supplied from a liquid supply source through a liquid supply path is ejected as a liquid droplet, and ejects the liquid droplet from the nozzle to a recording medium to perform a recording process, a first detecting section that detects a vibration waveform of the pressure chamber, which is vibrated when an actuator is driven to cause the pressure chamber communicating with the nozzle to vibrate, to detect a state inside the pressure chamber, and a second detecting section that reads a pattern formed on the recording medium by ejecting the liquid droplet from the nozzle to detect an ejection state of the liquid droplet.

A liquid ejection device includes a liquid ejection unit having a first nozzle group configured to eject a first liquid to a cloth conveyed, and a second nozzle group configured to eject a second liquid to the cloth, and a wiping unit configured to wipe a nozzle surface on which the first nozzle group is disposed, wherein the first liquid is aqueous ink and the second liquid is a liquid including a softening agent, and the second nozzle group executes a softening treatment of ejecting the second liquid to the cloth, and a water repellent treatment of making the second liquid adhere to the nozzle surface.

An ink jet printhead, an ink-jet printing device and a display manufacturing device are provided for eliminating or reducing droplets on areas outside of the printing area during the ink-jet printing process, thereby improving product quality. The ink jet printhead provided in the disclosure comprises at least one nozzle and a droplet removing component disposed in at least one edge areas area around the area where the at least one nozzle is located, the droplet removing component being used for eliminating or reducing droplets at positions corresponding to the edge area where the droplet removing component is located.

A screen cleaning apparatus (2) and method, wherein: a screen cleaning head (3) is operative to contact a surface of a printing screen (PS), the screen cleaning head (3) includes a screen contact element (17) over which a cleaning sheet (7) is in use disposed, the screen contact element (17) comprises a first section (17a), which is configured to support one of a dry section or a wet section of the cleaning sheet (7) thereabove, a second, vacuum section (17b), at which a vacuum is provided to draw a vacuum therethrough, and a third section (17c), which is configured to support the other of a wet section or a dry section of the cleaning sheet thereabove; and a support (11) to which the cleaning head (3) is supported and which is movable over the surface of the printing screen (PS) to provide for cleaning of the same.
