摘要:
Data processing method and apparatus for converting data such as character data or image data of a resolution X into data of a resolution Y which are effective for use in, particularly, a recording apparatus such as an ink jet printer or the like. The data processing method comprises a first dividing step of dividing the data of the resolution X in the main-scan direction every A bits; a first converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a first conversion pattern table; a second dividing step of dividing the data which was obtained by repeating the conversion by the first converting step by a number of times as many as a plurality of lines in the sub-scan direction every A bits; a second converting step of converting the divided A-bit data into the B-bit data of the bit number B by using a second conversion pattern table; and a reducing step of reducing the data of the resolution Y obtained by the second converting step by a thinning process by using a third conversion pattern table.
摘要:
A host computer acquires information about an amount of remaining ink of a printer. In response to the acquired information about the amount of remaining ink, the host computer displays a message on a display screen so that a user can select whether an ink cartridge is to be replaced with a new one or the process is to return to a previous routine without replacing the ink cartridge.
摘要:
A liquid container including a first chamber for containing a reservoir of liquid, a second chamber containing a negative pressure producing material, an air vent for fluid communication with ambient air, a liquid supply port for supplying liquid out of the second chamber, a communication path for fluid communication between the first and second chambers where the first chamber is generally sealed by the ambient air except through the communication path, and a wall extending from the communication port. The communication path has a first region for permitting movement of air from the second chamber to the first chamber and a second region for permitting movement of the liquid from the first chamber to the second chamber.

There is disclosed an ink-jet head for performing recording by discharging an ink, including a discharge port for discharging the ink, and an ink channel which communicates with the discharge port and is provided with a discharge energy generating element for discharging the ink. An optical element is arranged at a position, corresponding to the ink channel, of the ink-jet head. There are also disclosed an ink-jet apparatus using the ink-jet head and a substrate for the ink-jet head.

A replaceable ink cartridge, usable with a bubble jet printer, includes a container having front, back, top bottom and side walls, the container being divided internally into a first chamber and a second chamber having a common partition extending downward perpendicularly toward the bottom wall to provide an opening between the chambers formed by the partition proximate to the bottom wall. The first chamber contains a reservoir of liquid ink and is generally sealed from ambient air except through the opening, and the second chamber has an air vent for admitting ambient air into the second chamber and an ink supply outlet in the front wall. The second chamber contains a sponge-like material for retaining ink, at least one groove in the second chamber side of the partition extending from the opening and terminating at a point partly up the partition to form an air flow passage from the second chamber to the first chamber, the sponge-like material being positioned in the second chamber to permit flow of air from the air vent to the groove when the level of retained ink in the sponge-like material is proximate to the point where the groove terminates. The container is removably mountable in a printer mounting with the bottom wall facing downward and the ink supply outlet facing an ink jet print head so that the ink supply outlet is connectable to an ink port of the ink jet print head.

A replaceable ink cartridge, usable with a bubble jet printer, comprises a container formed by front, back, top and bottom walls, and two side walls providing major surfaces of said container, with a partition dividing the container into first and second chambers communicating with each other through an opening formed by the partition proximate to the bottom wall. The first chamber, which is generally sealed from ambient air except through the opening, contains a reservoir of liquid ink, and the second chamber contains a sponge-like material for producing a negative pressure whereby ink is deliverable from the first chamber through the opening to an ink supply outlet in the front wall proximate to the bottom wall. The partition has at least one groove for forming an air flow passage from the second chamber to the first chamber through the opening, thereby permitting introduction of air into the first chamber and flow of liquid ink to the ink supply outlet through the opening. The container is removably mountable in a printer mounting with the bottom wall facing downward and the front wall facing an ink jet print head so that the ink supply outlet is connectable to an ink port of the print head.
摘要:
A liquid container for containing printing liquid for supplying to a recording head for an ink jet recording apparatus, the container includes a first chamber containing a negative pressure producing material and having a printing liquid supply port connectable to a recording head for allowing printing liquid to be supplied to the recording head and an air vent for allowing ambient air to enter the container, and a second chamber which provides a printing liquid reservoir for the first chamber and is substantially closed apart from a communication port communicating with the first chamber to allow the printing liquid to flow into the first chamber and to allow air to be introduced into the second chamber from the first chamber. The second chamber comprises a replaceable printing liquid chamber.

A leather coloring process for carrying out coloring on a natural leather, or a natural leather which has been subjected to degreasing. The coloring process is accomplished by ink-jet coloring on at least a partial area of the natural leather.
摘要:
A liquid container for a liquid jet recording apparatus comprises a first chamber containing negative pressure producing material and having a liquid outlet connectable to a liquid jet head to supply liquid from the container to the liquid jet head and an air vent for allowing ambient air into the container, wherein the liquid outlet is provided in a bottom portion of the first chamber. A second chamber communicates with the first chamber by a communication path and is substantially hermetically sealed. A wall extends upwardly from the communication path of the first chamber. An ambient air introducing path is provided for between the wall and the negative pressure producing material extending from a point partly up the wall toward the communication path for introducing ambient air into the second chamber.
