Patent number: 7222937Abstract: A drop emitting device including a first linear array of columnar arrays of first nozzle pairs and a second linear array of columnar arrays of second nozzle pairs, wherein the first linear array and the second linear array extend along an X-axis, and wherein the second linear array is adjacent the first linear array such that each first nozzle pair has an associated second nozzle pair displaced therefrom along a Y-axis that is orthogonal to the X-axis. The columnar arrays of first nozzle pairs and the columnar arrays of second nozzle pairs extend obliquely to the X-axis.Type: GrantFiled: January 10, 2004Date of Patent: May 29, 2007Assignee: Xerox CorporationInventors: John M. Brookfield, Rodney B. Hill, James D. Padgett, John S. Moore, Eric Segerstrom, Brian E. Sonnichsen, Christine M. Greiser
