Abstract
A liquid ejecting apparatus includes: a first head disposed such that an arrangement angle is a first angle; a second head disposed such that an arrangement angle is a second angle, which is greater than the first angle; a first circulation mechanism circulating liquid between a first reservoir and the first head; a second circulation mechanism circulating liquid between a second reservoir and the second head; and a control unit controlling the first and the second circulation mechanisms. The control unit performs circulation cleaning, in which the liquid is circulated, on multiple heads including the first head and the second head. The amount of the liquid circulating through the first head during the circulation cleaning is a first amount, and the amount of the liquid circulating through the second head during the circulation cleaning is a second amount that is greater than the first amount.
