4. Project Background https://edge.rit.edu/content/P09505/public/Home Senior Design I – Mid Project Review Xerographic digital printers are very energy intensive, specifically the fusing sub-system. This is largely due to the fact that during the fusing process toner is heated to well above its melting point, to enable heat flow, and allow the toner to adhere to the paper. • Senior Design Project as Stated on Edge: “Re-consider the design of an extremely low power, non-thermal fusing system” 4

5. How a Fusing Sub-System Works Traditional Toner Fusion: Temperature + Pressure + Heat = Fused, Adhered Toner Heat Discrete, loose toner Fused, adhered toner Nip Pressure Image by: David Thompson, Xerox Corp.

6. Project Scope The purpose of this project is develop a fusing sub-system that uses pressure instead of thermal energy to fuse toner to paper with the aim of fitting into the Xerox Workcentre Pro 45/55 printer. Senior Design I – Mid Project Review 6

7. Customer Requirements • Most Important Customer Requirements: • Paper is not damaged • Uniform pressure along nip • Fit into current Xerox Workcentre 245/55 Pro • Use pressure only to fuse toner to paper Senior Design I – Mid Project Review 7

8. Senior Design 2 Deliverables Senior Design I – Mid Project Review • Physical Hardware: • Working cold pressure fusing system • One working prototype with multiple configurations • Parametric Analysis: • Effect of different roller skews on: • Uniformity of pressure across the nip • Damage to paper • Various loads and their effect on: • Uniformity of pressure across the nip • Damage to paper • Analytically test the max load design can handle • Effects of paper thickness • Analytically examine the effects of roller lengths • Verification of theory that additional rollers will generate a more uniform pressure across the nip
