DROPLET EJECTION APPARATUS AND METHOD OF CLEANING THE SAME |
| 摘要 |
A droplet ejection apparatus includes: a number of droplet ejection units each of which has a nozzle connected to a liquid chamber and an actuator for expelling droplets of a process liquid; a cleaning station; and a control system arranged to control a relative movement of the droplet ejection units and the cleaning station and to immerse the nozzles into a cleaning liquid, wherein a heater is provided for heating the droplet ejection units, and the control system is adapted to activate the heater when the droplet ejection units and the cleaning station are moved or have been moved towards one another, and to deactivate the heater to allow the droplet ejection units to cool down while the nozzles are immersed in the cleaning liquid. |
