Abstract
A droplet discharge device includes a droplet discharge head, a supply unit, and a controller. The droplet discharge head discharges droplets of a coloring liquid. The supply unit supplies the coloring liquid to the droplet discharge head. The controller controls each unit. During at least a part of a maintenance period after a discharge period in which droplets of the coloring liquid are discharged from the droplet discharge head, the controller controls the supply unit to supply the coloring liquid having a viscosity lower than that of the coloring liquid in the discharge period to the droplet discharge head.
Claims13
A droplet discharge device, comprising:
- a droplet discharge head configured to discharge droplets of a coloring liquid;
- a supply unit configured to supply the coloring liquid to the droplet discharge head;
- and
- a controller configured to control each unit, wherein
- during at least a part of a maintenance period after a discharge period in which droplets of the coloring liquid are discharged from the droplet discharge head, the controller controls the supply unit to supply the coloring liquid having a lower viscosity than that of the coloring liquid in the discharge period to the droplet discharge head.
A maintenance method for a droplet discharge device comprising:
- a droplet discharge head configured to discharge droplets of a coloring liquid;
- and
- a supply mechanism configured to supply the coloring liquid to the droplet discharge head, the maintenance method comprising:
- during at least a part of a maintenance period after a discharge period in which droplets of the coloring liquid are discharged from the droplet discharge head, controlling the supply mechanism to supply the coloring liquid having a lower viscosity than that of the coloring liquid in the discharge period to the droplet discharge head.
