Ink-jet recording apparatus

An ink-jet recording apparatus comprising:

• a manual feed tray on which a sheet is placed;
• a motor rotatable in a first direction and a second direction opposite to the first direction;
• a conveyance roller configured to be rotated in a forward direction by a transmission of a rotation of the motor in the first direction so that the sheet on the manual feed tray is supplied into a conveyance path and is conveyed in a conveying direction, the conveyance roller being configured to be rotated in a reverse direction opposite to the forward direction by a transmission of a rotation of the motor in the second direction;
• an encoder configured to detect a rotation of the conveyance roller;
• a recording head disposed downstream of the conveyance roller in the conveying direction and having a nozzle face on which a plurality of nozzles are formed, the recording head being configured to eject an ink to record an image on the sheet;
• a cap configured to be put into a first posture in which the cap covers the nozzle face and into a second posture in which the cap is away from the nozzle face;
• a suction pump configured to be driven by a transmission of the rotation of the motor in the second direction;
• a switching portion comprising a plurality of ports including at least a first port and a second port, wherein the switching portion is configured to switch a state of communication between the first port and the second port by a transmission of the rotation of the motor in the first direction, the first port being connected to a suction port of the suction pump, the second port communicating with an inside space of the cap;
• and
• a controller electrically connected to the motor and the encoder,
• wherein, when the controller receives an image recording command for the sheet placed on the manual feed tray in a state in which the cap is in the first posture, the controller is configured to rotate the motor in the first direction by a first rotation amount smaller than a complete switch rotation amount, the complete switch rotation amount being a rotation amount of the motor required to put the state of the communication into a first communication state, which is a state of the switching portion in which recording is performed,
• wherein the controller is configured to rotate the motor in the second direction by a second rotation amount equal to or less than the first rotation amount after the rotation of the motor in the first direction by the first rotation amount, and
• wherein the controller is configured to rotate the motor in the first direction by a difference rotation amount between the complete switch rotation amount and the first rotation amount so that the state of the communication is put into the first communication, after the rotation of the motor in the second direction by the second rotation amount.
