Low Energy Printing Project P10505 David Hatch

Outline Introduction Competitive Technologies Objectives and Markets Project Requirements Future Vision

Introduction The goal of P10505 is to reduce the energy used in fusing toner onto printing material. After the ink has been printed onto the paper it undergoes a fusing process to bind it to the paper’s fibers. Current technology uses high energy thermal or light processes to affix the toner to the paper. P10505 intends to accomplish toner bonding without using thermal or radiant energy to fuse the ink.

Project Introduction Project Name and Number o Low Energy Printing Project, P10505 Project Family o Printing Systems Track o Aerospace and Energy Systems Guide and Consultant o Bill Nowak, Xerox Corporation, Principal Engineer - Motion Quality Systems Primary Customer o John Knapp, Xerox Corporation, Research Fellow P10505 is a continuation of P Due to this, a lot of groundwork has been laid for the current iteration of the project.

Fuser Descriptions Flash fusing uses high intensity strobes to fix toner to paper. Images: Xerox.com Hot-roll fusing uses heated rollers and pressure ( lbs) to melt the toner and force it into the paper.

Cold Pressure Fusing High pressure ( lbs) application without thermal or radiant heat. Current toner formulas cannot work with cold pressure fusing. Design is being focused on what toner is expected to do in the near future. Disadvantages are paper wear and loss of quality from smearing and uneven distribution. Image: Waseda University

Stakeholders Xerox corporation o Wants a developed technology to implement in printer designs. o New innovative approaches and employee opportunities MSD team o Want a challenging and educational learning experience. o Opportunity for future growth. Engineering Department o Wants a rewarding student experience and a satisfied sponsor.

Proprietary Constraints Since MSD is in the public domain, Xerox does not want to divulge information to team members beyond the scope of the project. The engineers at Xerox want to see how successful the current project is before moving forward. Because of this, information on next year’s project will be limited until the conclusion of the quarter or possibly until next year.

Objectives Primarily – make money o Decrease energy use to make the printer more marketable. o Open third world markets unavailable to high energy printers. Augment company image. o Establish customer loyalty Reduce energy footprint.

Industrial use o High volume, continuous production  Books, magazines, printing labels etc. Office use o Medium volume, intermittent use  Reports, presentations etc. Personal use o Low volume, sporadic use Markets Image: xerox.com

Needs Statements I.The fuser uses less energy than current fusers. II.The fuser creates a high quality, long lasting print image. III.The fuser can function at rates equal to or better than the rest of the printer. IV.The fuser can be implemented in current printer designs. V.The fuser can be manufactured easily and at low cost.

Resources Xerox prefers to manufacture in-house for billing purposes and quality control. Potentially all manufacturing needs will be accomplished in this manner. CNC work may be completed in the Brinkman lab. Technical TA’s who are closely associated with Xerox. Project guide is a Xerox engineer.

Future Plan This Quarter Follow P90505 closely through the remainder of the quarter. Meet directly with John Knapp. Next Year Re-interview Xerox for any design changes. Evaluate final success of P09505.
