If a single line of data is recorded, the carriage 1 returns to 'B' position, the recording paper 6 is fed by the width of the recording width section P in C'' direction and this action is again repeated. After this recording action is performed over a specified number of lines, the carriage 1 is driven in 'B' direction using a control circuit 28, and the recording heads 2a to 2d are moved to a position opposed to a capping member 18. Consequently, the capping member 18 is displayed to 'D' position and an elastic element 19 is pressed against each recording head. A signal is connected to the recording head drivers 21a, 21b, 21c, 21d from the control circuit 28 under the above condition. Then ink droplets are discharged from each recording head. Next, the capping member 18 is displaced to 'E' position. Thus it is possible to prevent ink from failing to discharge while ink consumption due to a blank discharge is minimized.
