ABSTRACT:
In order to prevent change in the properties of recording liquid such as surface tension, viscosity, etc. a recording head is provided with an integral temperature sensor. The temperature controlling operation is performed in response to an output of the temperature sensor to maintain the recording liquid within a predetermined temperature range. In order to correct the variation in the properties of the individual temperature sensors, the main apparatus contains a reference temperature sensor. The temperature sensor of the recording head is corrected in its output on the basis of comparison between the temperature sensors. The recording head is provided with information representative of a property of the temperature sensor of the recording head. By the mounting of the recording head into the apparatus, the information is read, and the output of the temperature sensor is corrected on the basis of the read information.
