  1. P10511: Miniaturization of Xerography Derek Meinke (ME, PM) Matthew Liff (ME) Tony Zhang (EE) Zaw Htoo (ISE)

  2. Project Description • The scope of P10511 is to create a test fixture that will allow the use of various charging devices along with multiple diameters of photoreceptors. • Test affect of charge uniformity with various device configurations and input parameters. • Xerox test fixture is currently limited in versatility.

  3. Project Description (cont.) • Reasons for Reducing Drum Diameter • Advances in Charging Technologies • Reducing Wear Rate of Photoreceptor • Higher Rotational Speeds for Higher PPM • Reduced Footprint for Charging Devices • Cost Effective • Increased Reliability

  4. System Objectives • Different Charger Configurations • BCR versus Scorotron • Photoreceptor Diameter • Variable Drum Speed • Ion Transfer • Charge Measurement (ESV)

  5. Roles and Responsibilities

  6. Team Values and Norms • Reasonably late to meetings is acceptable but not repeatable. Leave a message for a team member if cannot attend. • At start of meeting, discuss team objectives for 5 to 10 minutes. • CC all group members when emailing project information; respond within 24 hours. • An understood consensus must be made for all decision making. • Record meeting minutes.

  14. Concept Generation (ME)

  15. 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)

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

  17. Closer Look at the Motors Photoreceptor Drive: S83-93 • Minimal Required Torque • 9 Pin Connector to Voltage Supply • Requires isolating motor ground from power supply.

  18. Motors (cont.) • ESV Drive: S57-51 • Delivers required torque for rotating threaded shaft • See next slide for the workings of the ESV unit

  19. Selecting a DAQ Device Data Acquisition & Analysis requires a few steps: Factors for Consideration

  20. Bill of Materials (EE & ISE) • FOR THE MOTORS • Motor Controller (NI PCI-7332) • $899.00 • Description: PCI / 2-Axis • http://sine.ni.com/nips/cds/view/p/lang/en/nid/14338 • Stepper Motor Drive (NI P70530) • $349.00 (x2) = $698.00 • Description: 1-Axis / 300 Watts • http://sine.ni.com/nips/cds/view/p/lang/en/nid/203933 • Total = $1597.00

  21. Bill of Materials (cont.) • FOR THE DAQ • Multifunction Data Acquisition Device (NI USB-6009) • $279.00 • Inputs: 8 Analog / 12 Digital • Outputs: 2 Analog / 12 Digital • USB Connection • http://sine.ni.com/nips/cds/view/p/lang/en/nid/14605#overview • Total =$1597.00 + $279.00 = $1876.00
