20100245462 | LIQUID EJECTING APPARATUS AND MAINTENANCE METHOD FOR A LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a liquid ejecting head having a nozzle formation surface with a nozzle that discharges a liquid. A cleaning member wipes the nozzle formation surface to remove liquid that has adhered thereto. An absorption member of a porous material deforms under pressure and includes an absorption surface that contacts the cleaning member to absorb liquid that has adhered thereto. A pressure member moves between a pressure position, in which the pressure member applies pressure to the absorption surface of the absorption member, and a non-pressure position, in which the pressure member does not apply pressure to the absorption surface. A movement mechanism moves the pressure member from the non-pressure position to the pressure position to cause the absorption member to deform, thereby dispersing the liquid absorbed by the absorption member from the cleaning member via the absorption surface into the interior of the absorption member. | 09-30-2010 |

20090179972 | LIQUID SUPPLYING METHOD, LIQUID SUPPLYING SYSTEM, AND LIQUID EJECTING APPARATUS - In a case where the depressurizer is driven so as to enable removal of any of the liquid containers for replacement in a state where the pressurized fluid is supplied through the pressurized-fluid passage to the individual liquid containers, the control section controls the individual open or closed states of the pressurization passage valve corresponding to a to-be-replaced liquid container that is to be removed for replacement and the pressurization passage valve corresponding to a remaining liquid container that continues to be used to become opposite to each other. | 07-16-2009 |
20090201336 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus including a liquid ejecting head which ejects liquid through nozzles, a liquid container with a sloped bottom surface which receives the liquid ejected from the nozzles, an absorber disposed in the liquid container which absorbs and stores the liquid ejected from the nozzles, and a suction unit which sucks the liquid held by the absorber and discharges the liquid from the liquid container. The liquid container includes a restriction portion which restricts the flow of the liquid in the absorber due to gravity, forming collection portions in the absorber where the liquid may be collected at a plurality of positions with different elevations when the liquid container is rotated so that the bottom surface is sloped away from the horizontal plane. | 08-13-2009 |
20090303282 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a nozzle for ejecting liquid and a sealing unit that seals the nozzle. The sealing unit moves between a sealing position for sealing the nozzle in a direction of movement and an off position. A slider guides the sealing unit to the sealing position by moving rectilinearly in one of two opposite directions. The slider guides the sealing unit to the off position by moving in the other of the two directions. A drive mechanism performs first and second movements for moving the slider in the one and the other directions, respectively by a drive force from a motor. A drive force transmitting unit transmits the drive force to the drive mechanism by rotating while engaging the drive mechanism. The drive force transmitting unit rotates in the same direction while transmitting the drive force as the drive mechanism performs the first and second movements. | 12-10-2009 |
