A method for manufacturing an ink jet recording head, which is provided with a recording elemental substrate having discharge port group for discharging ink, an electric wiring substrate electrically connected with the recording elemental substrate, and a supporting member for holding and fixing the recording elemental substrate and the electrical wiring substrate, comprises the steps of injecting thermohardening filler into a filler retaining portion communicated with the sealing area requiring sealing; filling the area with the thermohardening filler injected into the filler retaining portion by heating the filler to flow; and hardening the filled thermohardening filler. With the structure thus arranged, it is possible to eliminate any electrical and structural defects in order to materialize a highly reliable and compact ink jet recording head.

Disadvantages relating to ink refill specific to an increase in a number of ink ejection openings in an ink jet print head is eliminated to provide a particularly excellent fast-response capability and ejection performance. More specifically, when an ink is supplied to a liquid chamber via an ink supply path and an ink supply opening formed in a support member and a print element substrate in a print head, and is then ejected from ejection openings, a pressure of an ink effected upon the ejection is transmitted to the ink supply path. This pressure, however, can be absorbed by air chambers via communication paths to reduce adverse effects of the pressure on ink refill in the liquid path after the ejection. In this case, since the air chambers and other components are structured to be closed with respect to the atmosphere, problems such as an increase in viscosity which are associated with communication of the air chambers and other components with the atmosphere can be prevented.

A recording apparatus has: a recording head having a liquid chamber and nozzles; a tank that stores the liquid which is supplied to the recording head; a liquid supply path that supplies the liquid from the tank to the liquid chamber; a supply pump provided on the liquid supply path; a liquid return path that returns the liquid from the liquid chamber to the tank; a return pump provided on the liquid return path; and a control unit that controls the supply pump and the return pump, wherein when the liquid is initially filled into the liquid chamber, the control unit drives the return pump so as to set the liquid chamber into a negative pressure state and subsequently drives the supply pump. The recording apparatus which can fill the liquid at a high speed without raising a pressure of a flow path can be provided.

A drying apparatus includes: a rotatable belt which has an outer surface and an inner surface, the outer surface contacts a sheet; a blowing mechanism which blows hot air on the sheet at a side of the outer surface; and a heating unit which includes a heating element and a contact surface which is disposed in contact with the inner surface. A plurality of rollers are arranged in a direction in which the sheet travels. The rollers are pressed against the outer surface of the belt with the travelling sheet being held between the rollers and the outer surface of the belt.

During a cleaning operation, the following steps are executed. The steps includes a first step of pressurizing ink in a supply path to overflow the ink from a nozzle, a second step of stopping the pressurization, a third step of executing wiping while the pressurization is stopped and a negative pressure is not applied, and a fourth step of applying a negative pressure to the ink at the nozzle to generate a meniscus.
摘要:
An ink jet print head is provided which allows an ejection opening-formed surface to be cleaned well and can improve a precision with which ejected ink lands on a print medium. For this purpose, conductive layers of a conductive material are formed on the support substrate and planarized. The liquid ejection substrates are mounted on the support substrate with high precision, without a sealing agent, that protects electrical connecting portions on the liquid ejection substrates, protruding from the ejection opening-formed surface.
