DROP DETECTION ASSEMBLY AND METHOD |
摘要 |
<p>A drop detection method comprises ejecting an ink drop that includes a fluorescent agent, illuminating the ink drop in flight with excitation light to excite the fluorescent agent, detecting fluorescence emitted by the drop in flight, having a longer wavelength than a wavelength of the excitation light, and, prior to such detecting, filtering out light having a shorter wavelength than the fluorescence wavelength; and a printer with drop detection assembly for performing the method.</p> |
