An ink cartridge for supplying the ink in an ink reserving chamber via an ink supply port into a recording head has a differential pressure valve mechanism disposed between an ink flow port and the ink supply port in the ink reserving chamber, whereby the ink is supplied an adequate amount to the recording head by opening or closing the differential pressure valve mechanism in accordance with an ink pressure of the recording head. As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the movement of the carriage.

A wiper device of a printer has four wiper units arranged in a line to wipe the nozzle faces of an inkjet head. Each wiper unit has a first intermittent gear and a second intermittent gear which sequentially mesh with first and second drive gears and sequentially transverse axis X a wiping operation and a cleaning operation. The wipers move vertically to the nozzle faces. A wiper cleaner lever rocks between a closed position covering the wiper and an open position not touching the wiper, moves through a path not interfering with the wiper in an opening operation, and through a path wiping the wiper and removing ink and other accretions from the wiper in a closing operation.

A wiper cleaner lever-rocks between a closed position covering the wiper and an open position not touching the wiper, moves through a path not interfering with the wiper in an opening operation, and through a path wiping the wiper and removing ink and other accretions from the wiper in a closing operation.

A wiper device enables to wipe selectively the unit heads to of an inkjet head has a simple, compact construction. The wiper device of a printer has four wiper units arranged in a line. When a drive shaft turns based on rotation of a wiper motor, the four wiper units operate sequentially from one end to the other in an outbound operating sequence, and operate sequentially in the reverse order in a return operating sequence. Four head units each have a row of unit heads, and a row of unit heads. The four wiper units can move to a position enabling wiping unit heads, and a position enabling wiping unit heads.

As a result, it is possible to supply the ink at a substantially constant pressure to the recording head without regard to the variation in the amount of ink or the-movement of the carriage.

A maintenance device for a fluid ejection head has a small, compact switching mechanism that can appropriately switch drive force from a drive source and drive a suction pump and a wiper. A maintenance devicehas caps() to() and wipers() to(), a suction pumpthat suctions waste ink from the caps() to(), a cap drive transfer mechanismthat moves the caps() to() in a cap movement direction V, a wiper-pump drive transfer mechanismthat moves the wipers and drives the suction pump, and a drive switching mechanismthat switches driving by the wiper-pump drive transfer mechanismto drive the suction pumpor move the wipers according to the position of cap movement.

Maintenance device for a fluid ejection head, a fluid ejection device, and a printer

Provided is a fluid ejecting apparatus including: a linear absorbing member which is disposed so as to face two or more nozzle rows adjacent to each other in a direction intersecting an extension direction of the nozzle rows while extending from one end of the nozzle row in the extension direction and being reversed at the other end thereof and to be turned back in a manner of reciprocating at least once in the extension direction, and absorbs the fluid ejected from the nozzles; a first movement mechanism which moves the absorbing member in a direction intersecting the extension direction of the nozzle row; and a second movement mechanism which moves the absorbing member while turning back the absorbing member so as to reciprocate at least once in the extension direction of the nozzle row.

Fluid ejecting apparatus

Provided is a fluid ejecting apparatus including: a plurality of nozzle rows which is arranged in the direction intersecting the extension direction of nozzles; a linear absorbing member which is suspended while being parallel to the nozzle rows or inclined with respect to the nozzle rows at a predetermined angle; a first movement section which relatively moves at least one of the absorbing member and the nozzle rows in the direction intersecting the nozzle rows; and a control section which performs a flushing process in which a fluid is selectively ejected from the nozzles facing the absorbing member toward the absorbing member while moving the absorbing member using the first movement section.

Provided is a fluid ejecting apparatus including a fluid ejecting head that has a nozzle row made of a plurality of nozzles and ejects fluid from the nozzle row. The fluid ejecting apparatus includes a line-shaped absorbing member that is provided to extend along the nozzle row and absorbs the fluid ejected from the nozzles at a position opposite the nozzles, and a retraction unit that retracts the absorbing member from the position opposite the nozzles by abutting on the absorbing member. The absorbing member is positioned at the position opposite the nozzles when the retraction unit does not abut on the absorbing member.

In the state in which a position of a movable member relative to the unit base portion is in a first displacement position, a first regulation portion provided in a seal member comes into contact with a unit base portion by the elastic force of a elastic member, whereby the posture of the seal member is regulated so that a sealing surface becomes parallel to a head surface of a liquid ejecting head, and wherein, in the state in which the position of the movable member relative to the unit base portion is in a second displacement position, a second regulation portion provided in the seal member comes into contact with the movable member, whereby the posture of the seal member is regulated so that the sealing surface is tilted with respect to the head surface.

Head repairing apparatus and fluid ejecting apparatus

A fluid ejecting apparatus, having a fluid ejecting head having a nozzle that ejects a fluid containing a solvent toward a target, includes a solvent holding member, disposed in a position that is opposite to a nozzle formation surface in which the nozzle of the fluid ejecting head is formed between the nozzle formation surface and the target but that is not opposite to the nozzle, that holds the solvent contained in the fluid.

Fluid ejecting apparatus with humidification member for moisturing ink

A fluid ejecting apparatus including: a fluid ejection head configured to eject fluid from a plurality of nozzles; a medium supporting member configured to support a medium at a position opposing the fluid ejection head, a thread-type fluid absorbing member configured to absorb the fluid ejected from the nozzles; and a moving mechanism configured to cause the fluid absorbing member to move between a first position opposing the nozzles between the fluid ejection head and the medium supporting member and a second position farther from a nozzle surface of the fluid ejection head than a transporting area of the medium, wherein the fluid is ejected from the nozzles to the fluid absorbing member at the first position.
