摘要:
A liquid injection recording apparatus comprises a recording head having discharge ports for discharging recording liquid therethrough, a liquid path communicating with the discharge ports, a liquid chamber communicating with the liquid path and energy generating elements utilized for discharging the recording liquid, a temperature sensor for detecting the temperature of the recording head and/or the recording liquid in the recording head, a storing tank for storing the recording liquid to be supplied to the recording head, a communicating path for switchably communicating between a supply system for supplying the recording liquid from the storing tank to the liquid chamber and a circulation system for circulating the recording liquid between the storing tank and the liquid chamber, a switching device for switching the communicating path to either of the supply system or the circulation system in accordance with temperature information from the temperature sensor, and a control circuit for controlling the switch.
