APPARATUS FOR OPTICALLY DETECTING INK DROPLETS |
摘要 |
<p>Ink jet printers include orifices which may become clogged or otherwise inoperative. This can cause printing defects which may go undetected for a substantial period because these printers usually operate unattended. An optical detector is provided for testing the operability of each ink jet orifice prior to the beginning of printing either a print cycle or a page. Ink is deposited on a member which moves the deposit through an optical path for detection. Absence of a deposit signals a malfunction.</p> |
