摘要： A temperature rise of a head due to a printing operation with a higher speed and a higher density is suppressed. To realize this, an inkjet printing head is provided in which a plurality of printing element substrates having an ejection opening array consisting of a plurality of ejection openings for ejecting ink are arranged on a support plate in a direction of the ejection opening array. The support plate includes therein a heat pipe and a flow path through which cooling liquid is flowed.

摘要： In an ink jet recording apparatus using a recording head that discharges ink by applying thermal energy produced in response to driving a heater to ink, a change in temperature occurring when the heater is driven is measured by a temperature sensor disposed directly below the heater. A discharge state for each nozzle can be determined by determination as to whether an inflection point is present in a curve representing the change in temperature occurring after the driving for discharging ink.

摘要： In order to prevent, in an operation for circulating liquid, an ejection port from sucking air or the ejection port from pushing out liquid, the subtank for temporally storing ink to be supplied to the ink jet head includes the air communication passage opened or closed by the air communication valve. The ink jet head is communicated with the subtank by the first passage and the second passage to constitute one circulation passage. In order to circulate the ink in the subtank into the common liquid chamber, the main pump is energized while the air communication valve is being closed. When the circulation operation is stopped, the air communication valve is opened immediately after the stoppage of the main pump, thereby eliminating the differential pressure between the common liquid chamber and the subtank within a short period of time.
