An ejection apparatus includes an ejection head having an ejection port, a droplet detection unit, an acquisition unit, a control unit, and a decision unit. The droplet detection unit detects that a droplet ejected from the ejection port has reached a predetermined position. The acquisition unit acquires information regarding a velocity of movement of the detected droplet. The control unit controls the ejection head to eject the droplet from the ejection port. The decision unit decides a number of consecutive ejections of a plurality of droplets from the ejection head based on the acquired information regarding the velocities of each of the plurality of droplets ejected consecutively and detected by the droplet detection unit. If the acquisition unit acquires the information regarding velocities of detected droplets, the control unit controls the ejection head to consecutively eject the droplets from the ejection head based on the decided number of consecutive ejections.

An irradiation device includes: an irradiation unit that is disposed downstream of an ejection unit that ejects droplets, in a movement direction of a medium that is moved relative to the ejection unit so as to form a gap between the irradiation unit and the medium, and that irradiates, with light, droplets that have been ejected from the ejection unit and landed on the medium; and a transparent member that is shaped like a belt, transmits light, and is moved through the gap relative to the irradiation unit.

A printer includes: a platen having an ink-collection slot extending across its width; a wick bar received in the ink-collection slot, wherein an upstream gap and a downstream gap are defined at either side of the wick bar relative to a media feed direction; a printhead positioned over the wick bar; and a vacuum chamber in fluid communication with the ink-collection slot. The wick bar is mounted on a rotatable shaft and the vacuum chamber comprises a scraper positioned for scraping the wick bar as it rotates past the scraper.

A printer housing with an upper portion and a lower portion with a cavity there between and wherein the upper portion and lower portion are connected by one or more hinges such that the housing opens about the hinged connection between the upper portion and the lower portion to expose the cavity there between. The hinged connection allows the upper portion to be lifted up with respect to the lower portion to expose one or more printer components for access through the cavity. One or more hinges secure the upper portion to the lower portion and wherein the one or more hinges are positioned on a same perimeter side of the housing such that the housing opens about one side.

An inkjet recording apparatus configured to perform recording operation by ejecting ink at least from a first recording head, includes an ink tank configured to contain the ink to be supplied to the first recording head, a tube configured to connect the first recording head and the ink tank, and a carriage including a first mounting portion on which the first recording head is mounted, a second mounting portion on which a second recording head is detachably mounted, and a contact portion electrically connected to the second recording head, and configured to reciprocate. A protection member protecting the contact portion can be detachably mounted on the second mounting portion.

In one example, a wedge shaped carriage to carry a printhead back and forth over a print substrate during printing.

An ink set where a droplet of ink is ejected in an amount of not less than 100 pL and not more than 5,000 pL. The ink set includes at least two inks including an ink A and an ink B and the ink set satisfies conditions 1 to 3 as measured, on a surface of a solid image with a 100% print duty which is printed on a polyester film using the ink A and the ink B, respectively, with respect to coordinates (L*.sub.A, a*.sub.A, b*.sub.A) of the ink A and coordinates (L*.sub.B, a*.sub.B, b*.sub.B) of the ink B in CIE L*a*b* color space.

A printing apparatus according to the present invention includes a plurality of ejection heads for ejecting liquid and a plurality of mist collection units configured to collect mist generated by the ejection heads that are disposed along a medium conveyance direction. The plurality of mist collection units include a first mist collection unit. The first mist collection unit is provided to be inclined to the upstream side of a medium conveyance direction with regard to a perpendicular line perpendicular to a floor. The first mist collection unit has a liquid retention part disposed at the upstream side than an ink mist suction hole.

An ink-jet printer includes: a base material transport mechanism for transporting a base material along a transport path in a transport direction; an ink ejection head having a lower surface opposed to the transport path, and an ink ejection port for ejecting ink toward the transport path; and a base plate having a lower surface opposed to the transport path over the transport path, and a mounting hole open in the lower surface, the ink ejection head being mounted in the mounting hole. The base plate includes an air flow hole that is a though hole penetrating through the base plate. The air flow hole has an air outlet open in a location downstream of the ink ejection port in the lower surface. Air passing through the air flow hole is ejected from the air outlet toward the transport path.

An inkjet recording apparatus includes a sheet feed section, an image forming section, a partition unit, an air inflow portion, a first sheet conveyance section, a second sheet conveyance section, and an air sucking and discharging section. The partition unit partitions an interior of an apparatus casing into a first space in which the image forming section is disposed and a second space in which the sheet feed section, the first sheet conveyance section, and the second sheet conveyance section are disposed. Air outside the apparatus casing is taken into the first space through the air inflow portion. The second sheet conveyance section includes a conveyance guide disposed downstream of the image forming section in a conveyance direction of a recording sheet. The air sucking and discharging section sucks air around the conveyance guide and discharges the air into the second space or out of the apparatus casing.
