An ejection apparatus includes a platen for supporting a recording medium, an absorber provided in the platen for absorbing liquid, an ejection unit for ejecting a plurality of types of ink including a first liquid containing a component to be deposited when the first liquid is ejected onto the absorber, and a second liquid different from the first liquid for suppressing deposition of the first liquid, a detection unit for detecting a state of a predetermined region of the absorber, and a control unit for controlling the detection unit to detect the state, and controlling the ejection unit to eject the second liquid to the predetermined region based on a result of the detection. When the first liquid is ejected to the predetermined region, the second liquid is ejected to the predetermined region after the ejection of the first liquid is finished, without using the result of the detection.

A printing apparatus includes a transport unit configured to transport a printing medium, a platen that includes a first support surface supporting the printing medium, a light-emitting unit configured to emit detection light toward a transport path of the printing medium, and a light-receiving unit provided adjacently to the light-emitting unit and configured to detect reflected light of the detection light, wherein a recessed portion is provided in the platen, the recessed portion including a primary reflection surface receiving the detection light and a secondary reflection surface receiving the detection light reflected by the primary reflection surface, and the first support surface and the secondary reflection surface overlap in an optical axis direction of the detection light.

A medium heating device includes a support portion configured to support a medium being transported, a heating unit configured to heat a medium supported by the support portion, and a detector configured to detect a temperature of the support portion. The support portion includes a metal plate including a first surface as the support face, an end portion of the metal plate is bent toward an opposite side to the first surface, the metal plate is fixed by a fixing portion and a fixing portion next to the fixing portion in a width direction, and a detection position of the detector is set to a position between the mutually adjacent fixing portions in the width direction.

With a cover in a closed position, a first internal gear and a first spur gear do not mesh with each other, and a second internal gear and a second spur gear do not mesh with each other. When the cover rotates by a predetermined angle around a first support shaft from the closed position, the first internal gear and the first spur gear start to mesh with each other. When the cover rotates by a predetermined angle around a second support shaft from the closed position, the second internal gear and the second spur gear start to mesh with each other.
