A head jetting property maintenance device includes a wiping device for wiping a recording head, a capping device for sealing the recording head, and a driving device including two planet gears for transmitting a drive force to the wiping device and the capping device and one rotary device for rotating the planet gears, and the driving device is able to drive the wiping device and the capping device in either of normal and reverse directions of the rotary device by switching the engagement of one of the planet gears to the engagement of the other of the planet gears and vice versa. With such a mechanical arrangement, there is no need that providing flags to detect the initializing positions of the cap and wiper are provided on cams for driving the cap and the wiper thereby effecting sensing them. Accordingly, the assembling and adjustment of the device are simplified, and the cost to manufacture the device is decreased.
