摘要:
An ink jet recording device has a recording head with a first array of ink discharge ports for emitting a first ink and a second array of ink discharge ports arranged for emitting a second ink, the first and second inks being of different colors, a main scanning element for moving the recording head relative to a recording medium for a main scanning during an emission of the inks by the recording head, and a subsidiary scanning element for moving the recording head relative to the recording medium by a predetermined subsidiary scanning distance during a non-ink-emission by the recording head. The first and second arrays of ink discharge ports are arranged with a separation between arrays that is not less than the predetermined subsidiary scanning distance in the direction by the subsidiary scanning element.

An ink jet recording apparatus for recording on a recording material with ink includes an ink jet recording head mounting portion, an ink jet recording head, a base plate, a feeder and a mounting device. The mounting portion is for mounting the recording head. The recording head has ejection outlets converged in a direction of ink ejection and inclined relative to the base plate. The feeder feeds the recording material. The mounting device is for mounting the ink jet recording head on the mounting portion so that the direction of ink ejection from the ink ejection outlets of the recording head is perpendicular to the recording material.

An ink jet recording apparatus comprises an ink jet head having an ink path communicating with a discharge opening for discharging ink; electrodes arranged in said ink path; a residual ink quantity detection means for detecting residual ink quantity in said ink path in accordance with a resistance value, current value or voltage value from said electrodes; and a correction means for correcting said resistance value, current value or voltage value in accordance with the difference in a resistance of the ink. This enables the correction means to compensate for different ink resistances and thus provide accurate residual ink detection even when different inks are used or ink resistance changes because of a change in ambient conditions.

In order to record an image having an excellent gradient by using inks of different densities, image data for dark ink and light ink are generated in accordance with the received image data. The generated data for dark ink is converted into a binary signal which is suitable for reproducing the resolution, while data for light ink is converted to another binary signal which is suitable for expressing gradient. In accordance with these binary signals, the discharge of each ink is controlled so as to record the image.

A method of exchanging a waste ink pack that stores waste ink discharged by repeated ink clearing operations performed on an ink jet head involves comparing a cumulative number of times the ink clearing operation have been performed using a particular waste ink pack with upper limit data based on the capacity of the waste ink pack. When the cumulative number reaches the upper limit data, an indication is provided that the waste ink pack should be exchanged for a new one, after which exchange a previous instruction to a recovery device to perform an ink clearing operation is performed. Ink clearing operations are then repeated with that waste ink pack until the number of such operations again reaches the upper limit data.

An ink jet recording apparatus includes ink ejecting outlets for ejecting ink, an ink container for containing the ink to be supplied to the ejecting outlets, ink supply passage for supplying the ink from the container to the ejecting outlets, a recovery system for forcedly ejecting the ink through the ejecting outlets. The recovery system repeats the forced ejecting action, and a quantity of the ink ejected by one forced ejecting action is larger than an inside volume of the ink supply passage.

An ink jet recording device includes scanning means for scanning ink jet recording heads in a scanning direction, each of the recording heads having plural ink discharge generating elements and plural discharge ports associated therewith, the discharge ports being adapted to perform a recording operation within a recording area which is a total area covered by the discharge ports during one scanning operation, supplying means for supplying recording signals corresponding to the recording area to a group of the ink discharge energy generating elements, and conveying means for conveying a recording medium relative to the recording heads. A control means controls the ink jet recording heads, supplying means and conveying means so that when the control means operates in a first recording mode, a recording within the recording area is completed in a single scanning operation, and when the control means operates in a second recording mode, the recording within the recording area is completed by plural scanning operations such that the recording area is subjected to the overlapped recordings by different discharge ports. The control means selects the recording mode according to a condition relating at least to a material quality of the recording medium.

An ink jet recording apparatus includes a plurality of ink jet recording heads for executing color recording, a recovery structure for maintaining and recovering a discharge state with respect to the plurality of recording heads, and a waste ink collecting container for collecting waste ink discharged from the recovery structure. The recovery structure has a plurality of waste ink collecting routes to the collecting container in accordance with each of the plurality of recording heads, and the plurality of waste ink collecting routes are disposed so as to discharge a predetermined kind of waste ink and other plural kinds of waste ink to different portions of the collecting container, respectively.
摘要:
This invention is a recording head cartridge which includes a plurality of inks having a density difference for an ink of one color, includes recording heads on a single substrate or in an adjacent aligned state, and integrates ink tanks for the plurality of inks, so as to reliably perform gradation recording while achieving a simple control circuit, and improvement in operability upon replacement. This invention also provides a structure in which ink tanks in the cartridge are integrated to determine a light/depth printing order, and have different volumes so as to improve advantages of replacement.
