Abstract: A liquid ejecting apparatus includes: a head portion which ejects liquid; a plurality of liquid reception portions which receive the liquid discharged from the head portion and in which flow-out ports of the liquid are provided on the bottoms; a suction pump which is connected to each of the flow-out ports of the plurality of the liquid reception portions and sucks the flow-out ports; and closure members each of which is provided in each of the plurality of liquid reception portions, is formed so as to float in the liquid, and closes each of the flow-out ports in a state where the liquid has flown out.

Abstract: A method for maintaining a fluid ejecting apparatus including an ejecting head that has an ejecting surface in which a plurality of ejecting ports that eject fluid are formed, and a maintenance portion that performs maintenance processing to recover the ejection of fluid from the ejecting ports and that has a cap member and a wiping member. The method includes performing capping processing to put the cap member on the ejecting surface and to suck, and then wiping processing to wipe the ejecting surface with the wiping member, and performing the capping processing again and then waiting a predetermined time without performing the wiping processing.

Abstract: A liquid ejecting apparatus for ejecting a liquid by using a liquid ejecting head provided with nozzles, includes: a cap capable of being mounted on the liquid ejecting head, wherein the cap includes a seal member which comes into close contact with the liquid ejecting head when the cap is mounted on the ejecting head, and the seal member is a member which is in a state where fluid is supplied in the interior thereof at least when the cap is mounted.

Abstract: A printer includes a recording head having a nozzle through which ink is ejected onto a paper sheet and a waste tank in which the ink is retained as waste liquid after having been drained from the recording head. A deposit of the waste liquid is formed in the waste tank. The printer has a suction pump used for forcibly drawing and draining the ink from the nozzle. The suction pump functions also as a gas blasting device that blasts gas to the deposit in the waste tank for blowing off the deposit. This suppresses the amount of the ink consumed in maintenance of the printer.

Abstract: The recording medium guide member is placed along the main scanning direction scanned by the carriage mounted with a recording head, and ink-receiver holes for receiving ink discharged from the recording head are formed on the guide member in positions beyond the edges of the recording medium being conveyed. Ink absorbing materials are placed in said ink-receiver holes, and a discharged ink accumulating means that cumulatively counts the amount of ink discharged into the ink absorbing materials is provided. The amount of ink discharged into the ink-receiver holes can be controlled by the discharged ink accumulation means so that contamination of the left and right edges or the top and bottom as well as left and right edges of the recording medium, caused by excessive ink collecting in the ink-receiver holes, can be avoided.

Abstract: Flushing regions for receiving ink droplets to be ejected when flushing signal is supplied to a recording head are provided in both of non-print regions situated at both sides of print region in order to prevent throughput during the flushing operation from deteriorating. A guide member having a slant surface is disposed between the recording head and an ink absorbing member to which the ink landed on the slant surface flows in order to reduce in size of the ink absorbing member. A porous sheet member closely faced to nozzle orifices of the recording head for receiving the ink droplets ejected therefrom is provided in order to prevent undesired mist of fine ink droplets from generating. A plurality of plate members closely faced to the nozzle orifices are provided at a predetermined angle with respect to the flight direction of the ink droplets in order to prevent the undesired mist from generating. The flushing operation is performed so as to prevent solidification of the ejected ink.

Abstract: A cap holder on which a cap member is formed is mounted on a slider which constitutes a capping device. This slider is driven along vertical direction by receiving driving force executed by moving a carriage, so that an interval between the cap member and a nozzle forming surface of a recording head is adjusted. As a result, since a stopping position of the carriage is controlled in response to an adjustment amount of a platen gap, a distance between the recording head and the capping device when a flushing operation is carried out can be controlled under proper condition. Also, even when the control operation is advanced to a capping condition, the capping device can cap the nozzle forming surface under proper pressure.

Abstract: An ink-jet recording apparatus has a flushing signal generating unit that generates a flushing signal, and a recording head provided with nozzles and capable of jetting ink particles through the nozzles when driven by the flushing signal. The flushing signal causes the recording head to jet only main ink particles through the nozzles. The ink-jet recording apparatus suppresses the formation of mist of ink particles during a flushing operation.
