Capacitive Drop Mass Measurement System

US Patent:
2011010, May 5, 2011
Filed:
Nov 2, 2009
Appl. No.:
12/610602
Inventors:
Christian Amoah-Kusi - Portland OR, US
David L. Knierim - Wilsonville OR, US
James Dudley Padgett - Lake Oswego OR, US
Assignee:
XEROX CORPORATION - Norwalk CT
International Classification:
B41J 29/38
US Classification:
347 14
Abstract:
An imaging device includes an image receiving surface movably supported within the imaging device and at least one printhead having a plurality of ink jets, each ink jet being configured to eject drops of ink on the image receiving surface. At least one sensing electrode is positioned adjacent the image receiving surface that outputs capacitance signals indicative of a capacitance in a gap between the at least one sensing electrode and image receiving surface that are output to a controller. The imaging device includes a drop mass detection mode of operation in which: at least one ink jet in the plurality of ink jets is actuated to eject drops of ink to form at least one test band on the image receiving surface; the image receiving surface is moved so that the at least one test band of ink is positioned in the gap; the at least one sensing electrode outputs a test band capacitance signal indicative of a capacitance with the at least one test band in the gap; and the controller modifies an operating parameter of the imaging device based on the capacitance indicated by the test band capacitance signal.
