Abstract:
A maintenance apparatus of an inkjet printer comprising:a housing disposed in a maintenance area; a print head having an ink spray nozzle; a wiper to wipe a surface of the ink spray nozzle when the print head is in the maintenance area; a wiping member disposed in the housing, the wiper being disposed therein; a drive motor to generate a rotational force; a power transmission device to transmit the rotational force; a wiping member convey unit to receive the transmitted rotational force and to convert the received rotational force into a horizontal force and to transmit the horizontal force to the wiping member; a stopper to stop the wiping member convey unit to place the wiping member at a predetermined position; and a control unit to control the drive motor so that the wiping member convey unit is in contact with the stopper first and second times to prevent the wiping member and the wiper from being erroneously positioned due to an abnormal repulsive force occurring in the wiping member convey unit when the wiping member convey unit comes in contact with the stopper, the repulsive force being caused by an outer impact or a change in a load of the drive motor.
