20090009541 | LIQUID DISCHARGING APPARATUS AND METHOD OF DISCHARGING LIQUID - A liquid discharging apparatus, which discharges liquid from a nozzle of a liquid discharging head on the basis of data, includes a controller and a member. When the controller is in a standby state where the liquid is not discharged from the nozzle on the basis of the data or after the controller has received a power OFF instruction, the controller performs a drawing operation in which the liquid is drawn to a side opposite to a discharge direction in which the liquid is discharged so as to at least form a space at a distal end portion of the nozzle. After the controller has performed the drawing operation, the member covers an opening of the nozzle. | 01-08-2009 |
20090009542 | LIQUID DISCHARGING APPARATUS AND METHOD OF DISCHARGING LIQUID - A liquid discharging apparatus, which discharges liquid from at least one nozzle on the basis of data, which includes a controller. When the controller is in a standby state and no liquid is being discharged from the at least one nozzle on the basis of the data, the controller performs a drawing operation wherein the liquid is drawn into the nozzle in a direction that is opposite to the direction that the ink is discharged from the at least one nozzle in order to form a space at a distal end portion of the at least one nozzle where no liquid is present. | 01-08-2009 |
20090009544 | FLUID EJECTING APPARATUS AND METHOD FOR TRANSPORTING FLUID - A fluid ejecting apparatus including a head that ejects fluid, a first fluid storing section for storing the fluid that is located below the head, a second fluid storing section for storing the liquid that is located above the first fluid storing section, a pumping mechanism capable of moving the fluid from the first fluid storing section to the second fluid storing section through the head, and a controller that alternates between a first control mode wherein the pumping mechanism moves the fluid from the first fluid storing section to the second fluid storing section and a second control mode in which the fluid is allowed to flow from the second fluid storing section to the first fluid storing section through the head. Upon receiving an instruction to turn off the power, the controller shifts to the second control mode and then turns off the power. | 01-08-2009 |
20090009556 | FLUID DISCHARGING APPARATUS - A fluid discharging apparatus including a head that has a nozzle which discharges fluid from the nozzle and a sheet shaped wiping member for wiping a nozzle surface of the head. The wiping member is moved relative to the nozzle surface so that portions of the wiping member are sequentially in contact with the nozzle surface in order to wipe the nozzle surface. | 01-08-2009 |
20090033707 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus for ejecting fluid includes a head capable of performing effective discharge during which the fluid is discharged to an object to be processed disposed at a predetermined position and capable of preliminary discharge during which the fluid is discharged separately from the effective discharge, a first head capping unit for preliminary discharge covering the head and receiving the fluid discharged from the head while the head performs the preliminary discharge, and a second head capping unit for moisturizing covering the head and moisturizing the head. The first head capping unit and the second head capping unit are stacked in such a manner that the second head capping unit covers both the head and an opening of the first head capping unit for receiving the fluid while the head does not perform either the effective discharge or the preliminary discharge. | 02-05-2009 |
20090085961 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus that ejects fluid includes: a head capable of performing effective discharge processing, in which the head discharges the fluid toward a processing object arranged at a predetermined position, and pre-discharge processing, in which the head discharges the fluid independently of the effective discharge processing; a carriage that carries the head and adjusts a position where the head discharges the fluid; a moisture retention head cap unit that covers a discharging surface of the head; a pre-discharge reservoir that receives the fluid discharged from the head when the head performs the pre-discharge processing; and an opening cap portion configured to cover an opening formed in the pre-discharge reservoir for receiving the fluid, when the moisture retention head cap unit covers the discharging surface. | 04-02-2009 |
20090096830 | FLUID EJECTION APPARATUS - There is provided a fluid ejection apparatus for ejecting a fluid including a head for ejecting the fluid and a moisture retention head cap device for retaining moisture of the head. The moisture retention head cap device is disposed so as to surround a periphery of the head to cover the whole of the head when retaining moisture of the head. | 04-16-2009 |
20090109257 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus that ejects a fluid includes a head that ejects the fluid, a first moisturizing cap device that covers the head to moisturize the head, and a first moisturizing liquid supply portion that supplies, to the first moisturizing cap device, a first moisturizing liquid for moisturizing the head when the first moisturizing cap device covers the head. The first moisturizing liquid supply portion has a first tank that stores the first moisturizing liquid. The first moisturizing cap device has a first moisturizing liquid storage portion that stores the first moisturizing liquid to be supplied from the first moisturizing liquid supply portion. The first moisturizing liquid supply portion supplies the first moisturizing liquid stored in the first tank to the first moisturizing cap device in accordance with a water head difference between the first moisturizing liquid stored in the first tank and the first moisturizing liquid storage portion. | 04-30-2009 |
20110134186 | FLUID EJECTION APPARATUS - There is provided a fluid ejection apparatus for ejecting a fluid including a head for ejecting the fluid and a moisture retention head cap device for retaining moisture of the head. The moisture retention head cap device is disposed so as to surround a periphery of the head to cover the whole of the head when retaining moisture of the head. | 06-09-2011 |
20110242206 | INK JET RECORDING APPARATUS AND MAINTENANCE LIQUID FOR INK JET RECORDING APPARATUS - An ink jet recording apparatus includes an ejection head which ejects an aqueous ink composition containing a resin component, a water-soluble organic solvent having a boiling point of 250° C. or less, a surfactant, and water; a first cap device which covers and moisturizes the ejection head; and a first maintenance liquid supply device which supplies a maintenance liquid to the first cap device. The maintenance liquid contains water and at least one water-soluble organic solvent of alkanediols having a boiling point of 250° C. or less and alkylene glycol monoether derivatives having a boiling point of 250° C. or less. | 10-06-2011 |
