| Title of Invention | DROPLET DEPOSITION APPARATUS AND A METHOD OF OPERATING THE SAME. |
|---|---|
| Abstract | Droplet deposition apparatus such as herein described as a printer comprises: fluid chambers such as channels (2) formed in a piezoelectric material; for each chamber (2), piezoelectric actuator means such as walls (11) of the channels actuable by an electrical signal to effect droplet ejection from that chamber; means for cyclically supplying electrical signals to each said actuator means for actuation thereof such as an LSI chip (16) electrically connected to electrodes contacting said actuator means; means (60) for measuring, within a period between the application of successive electrical signals to a said actuator means, a temperature dependent electrical property of said actuator means to provide a signal having a magnitude dependent on the temperature of fluid (4) in a fluid chamber associated with said actuator means; and means for adjusting the magnitude of the actuating electrical signals depending on the magnitude of the temperature dependant signal. A method of operating the droplet deposition apparatus is also disclosed. |
