Abstract

A liquid ejection apparatus that can suppress occurrence of condensation in a printing head without causing an increase in size of the apparatus is provided. To this end, a first air flow generation structure is arranged in a position that is not in a conveyance direction with respect to the printing head and arranged so as to be able to blow an air flow to an ejection port surface of the printing head. In addition, a heat source is provided between a first air flow generation unit and the printing head to increase a temperature of the air flow from the first air flow generation structure.

Claims19

Dependent claims

A liquid ejection apparatus, comprising:

a printing unit in which an ejection port from which a liquid is ejected onto a printing medium is arrayed in a second direction crossing a first direction in which the printing medium is conveyed;
a first air flow generation unit that can generate an air flow;
and
a heat source that can generate heat, wherein
the first air flow generation unit and the printing unit are arranged in a position in which the first air flow generation unit and the printing unit overlap in the first direction, and the air flow generated by the first air flow generation unit passes through the heat source and reaches an ejection port surface provided with the ejection port in the printing unit.
