Abstract: A printing device includes a printing apparatus that includes a transport unit including a roller pair that nips and transports a medium, a printing unit that prints on the medium and a first sensor that detects the medium or a mark at a position downstream of the roller pair. The printing device also includes a first motor capable of driving the roller pair to a non-nipping state and to a nipping state, and a controller that controls the transport unit and the first motor so as to perform an assistance operation to assist setting of the medium. The assistance operation performed by the controller. When the first sensor detects the medium or the mark, the controller causes the medium to be nipped by the roller pair, and a skew correction operation in which the medium is transported and reverse transported is performed.

Abstract: A printing apparatus includes a carriage and a control unit. The carriage includes a head configured to move in a first direction, and a light emission unit configured to relatively move in a second direction. The light emission unit includes a first emission group and a second emission group arranged in the second direction. The first emission group is disposed at a position that overlaps with the plurality of nozzles in the first direction. The second emission group is disposed at a position that does not overlap with the plurality of nozzles in the first direction. The control unit is configured to perform a first mode in which ultraviolet light is emitted from the first emission group and the second emission group, and a second mode in which ultraviolet light is not emitted from the first emission group and ultraviolet light is emitted from the second emission group.

Abstract: A printing apparatus includes a body portion and a carriage configured to move in a first direction along a first axis and in a second direction along a second axis orthogonal to the first axis. The carriage is mounted with a head configured to eject ink toward a medium and an irradiation unit configured to irradiate the medium with ultraviolet rays arranged side by side in the first direction. The irradiation unit includes a first contact portion and is supported movably in the second direction relative to the head. Movement of the carriage in the second direction brings the first contact portion and a second contact portion provided at the body portion into contact with each other. The irradiation unit moves in the second direction relative to the head as the carriage moves while the first contact portion and the second contact portion are in contact with each other.
