1. Electrophotographic Development and Transfer Station Update Week 2 Progress Report Ben Nguyen Dan Prosser Adam Regula Steve Snyder Amar Mohamed

2. Project Description Produce a LabView controlled, xerographical fixture that puts toner on paper. The LabView user interface should contain graphical outputs from the fixture, as well as, controls for multiple inputs. This project is a continuation of P09503. Customer: ◦ Marcos Esterman (RIT) ◦ John Knapp (Xerox)

3. Device Description Contains 5 subsystems ◦ Charging Station: Applies a uniform charge to the photoreceptor ◦ Exposure Station: Shines light on the photoreceptor to remove charge from the imaged area ◦ Development Station: Applies charged toner particles to the photoreceptor ◦ Pre-Transfer Erase Station: Reduces photoreceptor charge to uniform value ◦ Transfer Station: Transfer toner from photoreceptor to paper

4. Customer Needs Need 1 Must be operational ◦ 1.1 Put toner on paper  1.1-1 All subsystems functional  1.1-2 Further optimization of subsystems ◦ 1.2 Able to be used for educational purposes  1.2-1 Also possibility for R&D Need 2 Safety ◦ 2.1 Voltages, etc. ◦ 2.2 Safety measure for stepping motor  2.2-1 Make sure velocity is controlled  2.2-2 Put in LabView/physical stopgaps to protect from improper operator input Need 3 Interface ◦ 3.1 Voltages/Velocities, etc. controllable by VI front panel ◦ 3.2 Certain metrics should be plotted and monitored

5. Project Manager: Lam Nguyen, Jr. (Ben) Meeting Time: weekly Monday 8pm-10pm Roles ◦ Ben: Interface Design, Safety ◦ Dan: Controls, Mechanical Testing ◦ Steve: Controls, Back-End ◦ Adam: Fixturing, Electromechanics ◦ Amar: Wiring Expert, Safety ◦ Jeff: LabView Expert (Master’s student) Knowns ◦ Issues the previous team had ◦ The components that have already been completed ◦ Goal of end product (teaching purposes, R&D) ◦ General overview of the system operation Unknowns ◦ Plan of attack ◦ Work breakdown structure ◦ Technical knowledge ◦ Subsystem team leads ◦ Bill of materials

6. Look Ahead No current issues with meeting deliverables Future Plans ◦ Risk identification ◦ Begin investigating operation of current machine  Determine need for new equipment (BoM) ◦ Determine subsystem team leads ◦ Quantify scope of work ◦ Develop plan-of-attack ◦ Confirm/clarify customer needs
