Quality Function Deployment Engineering Metrics and Technical Targets
Quality Function Deployment Benchmarking – Customer Requirements Customer Requirements Paper is not damage High quality image (Xerox quality) Image has a low gloss Fit into current Xerox Workcentre 245/55 Pro Use pressure only to fuse toner to paper Accept paper in orientation it currently enters fuser (SHF / LHF) Compatible with other Xerox models (preferred color printer of same size) Sub-system cost less then current system Easy of manufacturing User must be able to safely clear jam in fuser Low Energy - non-thermal Technology can be used up and down along Xerox stream Fuser last life of product (roughly 3 million prints) at least 100,000 prints Standard office grade paper (20/24 pound paper) Customer Perception 1 Worse Better Ab Ab N/A Ab N/A Ab Ab N/A Ab A: Two Roller Cold Pressure System (Patent 4,372,247) b: Three Roller Cold Pressure System (Patent: 4,444,486)
