Abstract
A liquid ejection apparatus for discharging a medium on which liquid is ejected by a discharge roller after ejecting liquid on the medium by a liquid ejection head includes a medium pressing roller for controlling floatation of the medium between the liquid ejection head and the discharge roller, the medium pressing roller being provided on a rotatable discharge frame, wherein the liquid ejection apparatus operates by switching between a first mode where the medium pressing roller moves to an upper position by rotation of the discharge frame and a second mode where the medium pressing roller moves to a lower position than the first mode to press the medium downward.
