Printing apparatus and cleaning method for printing apparatus

A printing apparatus comprising:

• a conveyance path through which a medium is conveyed;
• a conveyance roller configured to convey the medium along the conveyance path;
• a support portion configured to support the medium conveyed through the conveyance path;
• a printhead configured to perform printing on the medium by ejecting droplets onto the medium supported by the support portion;
• and
• a controller configured to control drive of the conveyance roller, wherein
• the controller causes the conveyance roller to perform intermittent conveyance of the medium in a direction from the conveyance roller toward the printhead on the conveyance path based on reception of an execution of a cleaning mode of cleaning the conveyance path.

• a printhead configured to perform printing on the medium by ejecting droplets onto the medium supported by the support portion;
• and
• a controller configured to control drive of the conveyance roller and the printhead, wherein
• the controller causes, based on reception of an execution of a cleaning mode of cleaning the conveyance path, the conveyance roller to convey the medium in a direction from the conveyance roller toward the printhead on the conveyance path, and causes the printhead to eject the droplets to thereby print a pattern with the droplets on the medium.

A cleaning method for a printing apparatus including

• a conveyance path through which a medium is conveyed,
• a conveyance roller configured to convey the medium along the conveyance path,
• a support portion configured to support the medium conveyed through the conveyance path,
• a printhead configured to perform printing on the medium by ejecting droplets onto the medium supported by the support portion, and
• a inverting path that branches from the conveyance path at a position at a backward direction side of the conveyance roller, inverts the medium conveyed in the backward direction, and then merges the medium with the conveyance path, defining a direction from the conveyance roller toward the printhead on the conveyance path as a forward direction, and a direction opposite to the forward direction as the backward direction, the method comprising
• causing the medium to reach at least the support portion by conveying the medium in the forward direction and then merging the medium with the conveyance path via the inverting path by causing the conveyance roller to convey the medium in the backward direction, and causing the conveyance roller to convey the medium in the forward direction.
