1. A liquid ejection apparatus comprising:
a liquid ejection section that ejects liquid onto a medium;
a transport belt that faces the liquid ejection section and transports the medium;
a cleaning member for cleaning the transport belt by coming into contact with the transport belt, the cleaning member being capable of switching between a contact state in which the cleaning member comes into contact with the transport belt and a separation state in which the cleaning member is separated from the transport belt; and
a control section that controls an ejection operation of the liquid by the liquid ejection section, a rotation operation of the transport belt, and switching of a state of the cleaning member, wherein:
when the control section performs a cleaning operation of cleaning the transport belt by the cleaning member, the control section executes, based on preset cleaning control information, a preliminary ejection that ejects liquid from the liquid ejection section to the transport belt in advance, and
as a preliminary ejection execution condition, the preset cleaning control information includes one or more of ejection duty at the time of erroneous ejection, humidity, temperature, and an elapsed time after the erroneous ejection.
