Inkjet recording apparatus comprising: a recording head provided with a plurality of heating resistance elements that generate heat for discharging ink from an ejection port by supplying energy; and a temperature detecting means for measuring the temperature of the recording head Control method,
A detection step of supplying a plurality of types of energy to the plurality of heating resistance elements of the recording head, and detecting a plurality of temperatures of the recording head corresponding to each energy by the temperature detection means;
Drive that determines drive energy supplied to the plurality of heating resistance elements when the recording head is driven based on the energy of the heating resistance element corresponding to the minimum temperature among the plurality of temperatures detected in the detection step A condition determination step;
A method for controlling an ink jet recording apparatus, comprising: A determination step of determining whether the drive energy determined in the drive condition determination step is different from the drive energy stored in advance in the storage unit of the inkjet recording apparatus;
A step of rewriting the drive energy stored in the storage means to the drive energy determined in the drive condition determination step when it is determined that the determination step is different;
The method for controlling an ink jet recording apparatus according to claim 1, further comprising: A non-discharge nozzle detection step of detecting non-discharge nozzles at the plurality of discharge ports of the recording head;
3. The method of controlling an ink jet recording apparatus according to claim 1, wherein the detection step is performed when an undischarge nozzle is detected in the undischarge nozzle detection step. The ink jet recording apparatus has an optical detection means for detecting ink ejection from the plurality of ejection openings,
4. The method of controlling an ink jet recording apparatus according to claim 3, wherein the undischarge nozzle detection step determines that the nozzle is an undischarge nozzle when the optical detection unit does not detect ink discharge. The non-discharge nozzle detection step determines that there is a non-discharge nozzle by detecting a current leak to ink when energy is supplied to the heating resistor element.
