Project Team, Faculty, & Customer
• Project Memberso Aniket Arora – Project Manager – ISEo David Hatch – Lead Engineer – MEo Jon Burville – MEo Eric Wilcox – MEo Tom Stojanov – EE
• Customero Mr. John Knapp - Xeroxo Mr. Tony Condello - Xerox
• Faculty Guide o Mr. Bill Nowak - Xerox
Project Background/Description• Changing customer
expectations from printers.
• Focus on sustainability (low energy consumption).• Energy Star
• Heat fusing consumes a considerable portion of energy.• Hence, Cold Pressure
Fusing.
• P09505 developed an initial prototype.• Issues with pressure
uniformity
