A liquid discharge apparatus includes: a head unit that has nozzles that discharge a column-shaped liquid; a liquid droplet generating unit that applies cyclically changing energy to positions of the column-shaped liquids discharged from the nozzles, which are separated from the nozzles, and that generates liquid droplets; and a direction changing unit that changes a flying direction of at least some liquid droplets of the generated liquid droplets.

A printer includes a printing unit including a printing head configured to eject ink onto a sheet and a sheet ejecting portion configured to eject the sheet after the printing head performs a printing operation, a scanner unit located above the printing unit and configured to read an image on a document, and a tank unit located on a lateral side of the printing unit. The tank unit includes a tank storing the ink to be supplied to the printing head and a housing covering the tank. The housing provides at least a front surface, a lateral surface, a rear surface, and an upper surface of the tank unit. A front surface of the printing unit is flush with the front surface of the tank unit when the printing unit has a front surface on a side of the sheet ejecting portion.

A liquid discharge apparatus includes: a head unit that has a plurality of nozzles that discharge a column-shaped liquid; a liquid droplet generating unit that applies cyclically changing energy to positions of the column-shaped liquids discharged from the plurality of nozzles, respectively, which are separated from the plurality of nozzles, respectively, and that generates liquid droplets; and a direction changing unit that changes a flying direction of at least some liquid droplets of the generated liquid droplets.

The invention relates to a print head of a binary continuous jet printer comprising: means for producing a plurality of ink jets in a cavity, delimited by lateral walls, and by an upper wall and a lower wall, means for separating drops or sections of one or more of said jets intended for printing from drops or sections that do not serve for printing, a slot, which passes through the lower wall, enabling the exit of ink drops intended for printing, a gutter for recovering drops or sections not intended for printing, means for injecting gas into the cavity, and for making this gas circulate, in the cavity, to the means for producing a plurality of ink jets in said cavity, then to the gutter.

A system includes a print head including multiple nozzles formed in a bottom surface of the print head. The nozzles are configured to eject a liquid onto a substrate. The system includes a gas flow module configured to provide a flow of gas through a gap between the bottom surface of the print head and the substrate. The gas flow module can include one or more gas nozzles configured to inject gas into the gap. The gas flow module can be configured to apply a suction to the gap.

A continuous printhead drop deflector system includes a gas flow duct including a wall, the wall including a porous member having pores through which liquid can flow and a liquid flow channel, the flow channel being separated from the air flow duct by the porous member, the flow channel includes; a first port for extracting liquid from a first portion of the liquid flow channel; a second port for supplying liquid to a second portion of the liquid flow channel; one or more paths in the liquid channel permitting fluid to flow from the second portion to the first portion; wherein liquid, supplied through the second port to the second portion of the liquid channel and through the one or more paths to the first portion of the liquid channel, contacts and wicks into the porous member before being extracted through the first port.
