  • Patent number: 5302971
    Abstract: A liquid-discharge recording apparatus includes a recording head, an emission signal generator, and a heating signal generator. The recording head includes electrothermal energy converting elements for generating energy used to emit liquid in response to an emission signal from an emission signal generated by the emission signal generator. The heating signal generator generates an electrical signal applied to the electrothermal energy converting elements of sufficient level for heating the liquid, without discharging, during a first heating mode when power is supplied to the apparatus and for generating an electrical signal during a second heating mode, subsequent to the first heating mode, when recording begins after an interruption in power supply. In addition, a controller is provided for controlling a heater such that the heater is deactivated when the discharge opening of the recording head is capped. A liquid-discharge recording method is applied to the liquid-discharge recording apparatus.
