What We Learned

 Charge device configuration is most important

(previously 4th).

 Easily interchangeable parts.  Repeatability is new customer need.  Don’t assume.

Risk Assessment

Risk Management Table - Revision 1 - 12/17/2009 ID Risk Item Likelyhood Severity Importance Action to Minimize Risk Owner 6Faulty equipment 2 2 4 Obtain quality equipment, look into

• btaining MSD locker

All members 7 ESV/Erase Lamp/Charger gap problems 2 2 4 Run multiple tests to determine best location, have faculty guide review fixture, make it variable Mechanical Engineer 8Weather affecting travel 2 1 2 Have good communication, use Tortoise SVN and EDGE, online chat discussions available All members 9Customer priority changes 1 2 2Constant communication with customer All members 14Hard to change components 2 3 6 Create a manual, use more clips than screws Mechnaical Engineer 15 Aluminum substrate is in contact with motor ground 1 3 3 Include a switch, use insulating material at contact, generate many concepts Mechanical / Electrical Engineer 18Lack of Labview skillset 3 2 6 Additional research time, utilize faculty expertise Industrial Systems Engineer

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
• High Voltage Supply (0 to ±10kV)
• 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 (Finished or Unfinished) Slope of the voltage across the 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?
