An apparatus is capable of securely cleaning foreign matter, such as ink, attached to a discharge port surface with good efficiency, even in the case of a broad discharge port surface such as in a full-line type apparatus, and capable of preventing a discharge defect of the ink or deviation in a discharge direction, so as to perform satisfactory recording. The driving IC receives a driving signal for driving a motor and controls the rotation speed of the motor using the driving signal. Operating system program stored in the NAND flash memory is transferred to a system memory for execution therefrom by the CPU after system boot. The device can further include an electronic marker located inside the volume of the housing, wherein the electronic marker periodically emits a signal. The testing device further includes a set of internal conductors called septa, at least two in number, each septum defining in the testing volume, by its configuration in the structure, an electromagnetic coupling with the object; at least a septum is arranged in such a way that its electromagnetic plane is separate and not parallel to the electromagnetic plane of at least another septum.
