Provided is a wiping device including: an impregnated member that is impregnated with a liquid, has a contact surface having lengths which are longer than that of a nozzle-formed surface in a longitudinal direction and in a transverse direction intersecting with the longitudinal direction of the nozzle-formed surface of an ejecting head that ejects an ejection liquid, and causes the contact surface to come into contact with the nozzle-formed surface such that the nozzle-formed surface is wetted; and a wiping member that wipes the nozzle-formed surface wetted by the impregnated member.

Wiping device and ejecting device

A liquid droplet ejection head includes: a nozzle plate that has a plurality of nozzles ejecting a liquid droplet; a flow path member that includes: pressure generating chambers that communicate with the nozzles; and liquid supply paths through which liquid is supplied to the pressure generating chambers; and a damper portion that is disposed in at least one part of a region, the region being on the nozzle plate, corresponding to the liquid supply paths, the damper portion reducing a fluctuation of an ejection amount of the liquid droplets to enable stable ejection.

Method of producing liquid droplet ejection head

A droplet ejecting device including: plural droplet ejecting heads that eject droplets; a transporting body, disposed to face nozzle surfaces of the droplet ejecting heads, that transports a recording medium; and a head holding member that holds the droplet ejecting heads movably along droplet ejecting directions respectively is provided.

An ink jet printer is disclosed which, only when ink is to be supplied, supplies ink from a main tank disposed outside a carriage and which can effect the supply of ink stably without the leakage of ink. When it is detected by an ink level sensor that the ink level in a second ink chamber of an ink tank has become lower than a predetermined position, pipes in ports are inserted respectively into slit valves provided in the second ink chamber. Then, by operating a pump, the air present in the second ink chamber is discharged by suction to increase a negative pressure in the second ink chamber, allowing ink to be supplied from a main tank into the second ink chamber. Thus, since the supply of ink is performed by a negative pressure, it is possible to prevent the leakage of ink from the portion where the pipe is inserted into the slit valve.

An airtight elastic cap of an ink-jet recording head and a storage container employing the airtight elastic cap provide high airtightness between a nozzle face and the airtight cap and minimizes ink leak from the recording head even when the head is mounted or dismounted, or when a storage environment changes suddenly. The airtight elastic cap includes a body and an inside wall provided inside thereof. A portion of the wall defines a first space and another portion defines a second space positioned continuously to a center of the first space. The storage container includes a container body that houses the ink-jet recording head and the airtight elastic cap, placed within the container body, that abuts against and protects an ink emission face of the ink-jet recording head while the ink-jet recording is housed.
