摘要:
In a print apparatus for performing a print by a scan of a print head with heaters generating thermal energy for ejecting ink, a temperature of the print head is detected before the scan of the print head, and when the detected temperature exceeds a threshold temperature, the print head is controlled to wait. Information relating to the cumulative number of drives of the heater in the print head is acquired and, based upon this information, the threshold temperature is changed to a lower temperature as the cumulative number of the drives increases. An excessive temperature rise of the head is restricted and also a throughput reduction is reduced as much as possible.
