Abstract

PURPOSE:To prevent the generation of clogging due to increased viscosity of an ink even under low-temperature low-humidity circumstances and thereby eliminate the possibility of defective ink discharge by regulating a heating means provided on a capping member on information from a temperature sensing means so as to obtain controlled temperatures which are higher than a lower limit ink discharge temperature and lower than a recording head temperature. CONSTITUTION:The temperature of a capping member are sensed by a temperature sensing element 23, and if said temperature are lower than a recording head temperature, a heating means 20 is actuated. In the meantime, if the temperature are higher, the heating means is stopped. This operation is performed by controlling the turning ON/OFF of a switch 22 through a driver 25. In this way, the temperature of the capping member are regulated to be higher than the lower limit ink discharge temperature TH and lower than the recording head temperature. Consequently, the drying and evaporation of ink inside a nozzle 10 are limited and temperature reduction and viscosity increase are prevented.
