Patent number: 7645491Abstract: Disclosed is a venting assembly for a dip coating system, a dip coating system utilizing such venting assembly, and related method for dip coating. These aspects are particularly directed for the production of organic photoconductor layers in imaging devices, and more particularly to drum photoreceptors. The venting assembly eliminates or significantly reduces coating defects otherwise occurring in the production of drum photoreceptors. Also disclosed are the drum photoreceptors produced by this assembly, apparatus and coating process.Type: GrantFiled: June 21, 2005Date of Patent: January 12, 2010Assignee: Xerox CorporationInventors: Steven D. Bush, Michael J. Duggan, Mark E. Klino, Peter Schmitt
