A fluid ejection device has a fluid ejection head that ejects fluid droplets onto printing paper; a carriage that carries the fluid ejection head; and a static elimination member or charged member affixed to either or both the fluid ejection head and carriage. The static elimination member is configured to contactlessly eliminate the electric charge of an object, and the charged member has a polarized charge.

A liquid discharge apparatus includes: a liquid discharge head; a conveyer that supports and conveys a medium; a blower that is disposed on the upstream side of the liquid discharge head or the downstream side of the liquid discharge head and suppresses the change of the posture of the medium by sending the air to the medium; a temperature adjuster that is disposed on the side of the blower opposite to the liquid discharge head in the medium conveying direction and adjusts the temperature of an object to a temperature higher than the ambient temperature of the liquid discharge head or a temperature lower than the ambient temperature of the liquid discharge head; and a blast controller sends an operation stop command or an air reduction command to the blower at a blast region-pass timing at which the medium passes through a blast region of the blower.

A nozzle plate includes a nozzle substrate and a liquid-repellent film. The nozzle substrate includes a nozzle to discharge liquid. The liquid-repellent film is disposed on a liquid discharge side of the nozzle substrate and including a fluororesin having a fluorine-containing heterocyclic structure with ether linkage in a polytetrafluoroethylene (PTFE) skeleton. The liquid-repellent film includes a slope region that slopes in a direction in which a film thickness of the liquid-repellent film is smaller toward an edge of the nozzle in a peripheral portion of the nozzle.

A spittoon beam system and a printer that includes a spittoon beam system. The system has a spittoon beam spanning and movably mounted to spaced spaced parallel tracks. The spittoon beam is driven along the tracks by a first motor and a second motor coupled to respective ends of the spittoon beam. A first motor driver is coupled to the first motor and a second motor driver coupled the second motor. The system is configured so that the first motor driver controls an output shaft speed of the first motor independently of the second motor driver, and the second motor driver controls an output shaft speed of the second motor independently of the first motor driver.

A liquid ejection apparatus includes a liquid ejection head including a nozzle forming face in which a plurality of nozzles through which liquid is ejected toward a droplet landing object are formed, and a protruding face protruding toward the droplet landing objet and disposed so as to surround the nozzle forming face, and a cap body including a bottom plate and a wall extending upwardly from the bottom plate and configured to seal the nozzle forming face within a sealing space formed by bringing a top portion of the wall into contact with the protruding face. Further, at minimum, a portion included in the wall and being brought into contact with the protruding portion is an elastic member including liquid repellency.

A material removal unit and a material removal method for a printhead. The unit comprising a pass-through opening provided under an ejection opening of the printhead and configured such that an ejected droplet can pass through the pass-through opening essentially without being affected; at least one conduit forming channel configured to form a conduit. Wherein the conduit is communicatively connecting an area surrounding the ejection opening with a connection point configured to remove excess material from the area surrounding the ejection opening. The conduit has at least one conduit opening close to the pass-through opening and is configured to transport the material to the connection point.

An inkjet marking apparatus 1, wherein a printing means 220 comprises a printhead 222 provided with a plurality of nozzles 224 in a direction intersecting the conveying direction of printing substrates P, the printhead 222 is supported so as to be movable in a direction in which the nozzles 224 are arranged, and a control means, at a time of nozzle change when the nozzles 224 to be used are changed, suspends the operation of a feeding means 10 to form a non-holding area on a carrier means 20 where the printing substrates P are not held in a holding part 22 and, after the printing substrates P are printed, moves the printhead 222 during a time when the non-holding area passes through a printing area A.

A liquid discharging apparatus includes multiple nozzle rows, in which a plurality of nozzles capable of discharging liquid onto a medium are arranged, that are arranged in an intersection direction intersecting with a nozzles-arranged direction where the nozzles are arranged, a shielding portion that shields an area between the nozzle rows, and a collecting portion that collects mist which is attached to the shielding portion and is generated due to discharging of the liquid from the nozzles.

A liquid ejecting head includes a head body which has a nozzle opening for ejecting a liquid and a first wiping surface to be wiped by a wiper; and a target wiping member which has a second wiping surface to be wiped by the wiper, wherein the head body and the target wiping member are lined up via a gap so as to face in the same direction as the first wiping surface and the second wiping surface, and an elastic member is elastic deformed and held in the gap to block the gap on a side of the first and second wiping surface.

A liquid discharge apparatus includes: a liquid discharge head; a conveyer that supports and conveys a medium; a blower that is disposed on the upstream side of the liquid discharge head or the downstream side of the liquid discharge head and suppresses the change of the posture of the medium by sending the air to the medium; a temperature adjuster that is disposed on the side of the blower opposite to the liquid discharge head in the medium conveying direction and adjusts the temperature of an object to a temperature higher than the ambient temperature of the liquid discharge head or a temperature lower than the ambient temperature of the liquid discharge head; and a blast controller sends an operation stop command or an air reduction command to the blower at a blast region-pass timing at which the medium passes through a blast region of the blower.
