What We Learned  Charge device configuration is most important (previously 4 th ).  Easily interchangeable parts.  Repeatability is new customer need.  Don’t assume.

Concept Generation (ME)  https://edge.rit.edu/content/P10511/public/Home

Concept Generation (EE)  Power supplies will be provided to us from our customer, Xerox.  Trek Cor-a-trol Model 610C High Voltage Supply o High Voltage Supply ( 0 to ±10kV ) o Current Supply ( 0 to 2mA rms )

Concept Generation (EE)  Recommended motors and specs have also been provided.  For Photoreceptor Drive ( S83-93 )  For ESV slide ( S57-51 )

Concept Generation (ISE/EE)  LabView User Interface Input Data Output Data Start/Stop Voltage across photoreceptor Velocity of photoreceptor Graph (Voltage Vs cross-sectional length of photoreceptor) Diameter of photoreceptor Graph (Current Vs Voltage if aluminum substrate is attached) Type of photoreceptor Slope of the voltage across the (Finished or Unfinished) photoreceptor Type of Charger

Action Items  How much does inner diameter of photoreceptor vary with outer diameter?  Should ESV scan speed vary with photoreceptor rotational speed?  Can power supply be turned on through LabView?
