20110122191 | LIQUID EJECTING APPARATUS AND CONTROL METHOD THEREOF - A printer controller generates a foam elimination flushing driving signal that includes a foam elimination flushing process driving pulse for eliminating foam within the ink flow channel by driving a piezoelectric element; a foam elimination flushing process for restoring the ejection capability of a recording head is carried out using the foam elimination flushing driving signal before ink within the ink flow channel is heated by a heating mechanism. | 05-26-2011 |
20120098884 | DISPENSING LIQUID USING ARRAY OF DISPENSING ELEMENTS - An array of liquid dispensing elements are positioned on a substrate. Each liquid dispensing element includes a liquid dispensing channel positioned on the substrate. The liquid dispensing channel includes an outlet opening positioned on a wall opposite the substrate. A diverter member is associated with the liquid dispensing channel. A liquid return channel is positioned on the substrate and is in fluid communication with the liquid dispensing channel. A liquid supply channel is positioned on the substrate and is in fluid communication with the liquid dispensing channel. A liquid supply passage extends through the substrate and is in fluid communication with the liquid supply channel. A liquid return passage extends through the substrate and is in fluid communication with the liquid return channel. A liquid is provided that flows from the liquid supply passage through the liquid supply channel, through the liquid dispensing channel, through the liquid return channel to the liquid return passage of the array of liquid dispensing elements. A liquid drop is ejected from the outlet opening of the liquid dispensing channel of one of the liquid dispensing elements by selectively actuating the diverter member of the liquid dispensing element to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel of the liquid dispensing element. | 04-26-2012 |
20120249670 | LIQUID DROPLET JETTING APPARATUS - There is provided a liquid droplet jetting apparatus, including: a liquid droplet jetting head in which a plurality of nozzles and a plurality of individual channels are formed; a purge mechanism; a judgment mechanism which judges whether or not a defective nozzle in which a jetting failure occurs is included in purge target nozzles; a heating mechanism which heats a liquid in the plurality of individual channels; and a controller which controls the purge mechanism and the heating mechanism. In a case that the judgment mechanism judges that the defective nozzle is included in the purge target nozzles, the controller controls the heating mechanism and the purge mechanism to heat the liquid in a part of the plurality of individual channels, which include an individual channel communicating with the defective nozzle, and to execute the purge operation for the purge target nozzles. | 10-04-2012 |
20140111574 | LIQUID EJECTING APPARATUS - A liquid ejecting apparatus includes a liquid ejecting head which is capable of ejecting a photo-curable liquid to be cured by irradiation with light from nozzles which open at a nozzle surface of a nozzle-forming member; a wiping unit for wiping the nozzle surface with a wiping member in contact with the nozzle surface, a portion of the wiping member in contact with the nozzle surface being made of cloth; and a heating mechanism for generating heat to heat the nozzle surface; wherein the wiping member is capable of wiping the nozzle surface in a state in which an ink splash of a photo-curable liquid attached on the nozzle surface has been softened by heating of the heating mechanism. | 04-24-2014 |
20150306877 | METHOD FOR CLEANING LIQUID EJECTION HEAD - A method for cleaning a liquid ejection head, including a flow path forming member forming a liquid flow path, a heat generating resistive element, and a coating layer covering the heat generating resistive element and in contact with the liquid, in which the heat generating resistive element is made to generate heat and the liquid is made to be ejected from ejection ports, the method including: applying a voltage to the coating layer to produce an electrochemical reaction between the coating layer and the liquid, and causing the coating layer to be eluted into the liquid, thereby removing kogation deposited on the coating layer; and causing the heat generating resistive element to generate heat and causing the liquid to be ejected from the ejection ports while a voltage is applied to the coating layer continuously or intermittently, thereby eliminating air bubbles generated due to the electrochemical reaction. | 10-29-2015 |
20150336385 | LIQUID EJECTION HEAD, METHOD FOR CLEANING THE HEAD, RECORDING APPARATUS PROVIDED WITH THE HEAD - Cleaning under appropriate cleaning conditions is performed by disposing an electrode pair for measuring conductivity in the same liquid chamber as that of a material layer (i.e., an upper electrode) of a surface of a thermal action portion to be eluted, and measuring conductivity of a liquid using the electrode pair before kogation is removed. | 11-26-2015 |
20160001561 | METHOD FOR CLEANING LIQUID EJECTION HEAD - A method for cleaning a liquid ejection head which includes applying a voltage to a coating layer of the liquid ejection head to cause the coating layer to be eluted in a liquid so that kogation deposited on a coating layer is removed. When removing kogation deposited on the coating layer, temperatures of the liquids in the liquid chambers are selectively changed among a plurality of liquid chambers. | 01-07-2016 |
