The arrangement includes a temperature detector for detecting the temperature of the head and a condensation detector for detecting condensation on the head, the temperature detector and the condensation detector being provided in the vicinity of the head, and a heater for heating the head. A controller causes the heater to be energized on the basis of the outputs from the temperature detector and the condensation detector if the head is below a predetermined temperature or if condensation exists on the head at temperatures above the said predetermined temperature.
