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

  2. Customer Requirements Pareto

  3. Engineering Metrics Pareto

  4. Risk Assessment Pareto Link to Risk Assessment Table rev2

  5. EE Wiring Schematic

  6. Detailed Design Iso

  7. Detailed Design Iso • Almost all parts are the same thickness for feasibility of manufacture (10mm). • Vertical components will be mounted onto an aluminum jig plate. • Vertical components will be supported with L-brackets or gussets.

  8. Detailed Design Charger

  9. Detailed Design Charger • Interference with charger or charger mount components with photoreceptor end caps. • Charger wires binding with mount components when sliding for alignment. • Sliding placement with gapping blocks.

  10. Detailed Design Motor

  11. Detailed Design Motor • Moment created from heavy photoreceptor motor. • Interference from photoreceptor motor cradle with smaller ESV motor underneath. • Collars for photoreceptor motor to shaft and ESV motor to lead screw.

  12. Detailed Design Photoreceptor

  13. Detailed Design Photoreceptor • Spring selection for correct compression to eliminate slippage. • Bearing selection • Angle of V-flanges on endcaps. • Notch in shaft, notch in endcap, key insert for driven side.

  14. Detailed Design Erase

  15. Detailed Design Erase • Thin metal bar to support erase light. • Bend for no interference with endcaps. • Notches for discrete placement (~1 inch gap).

  16. Detailed Design ESV

  17. Detailed Design ESV • Bearing selection. • ESV mount guide design (delrin or aluminum?). • Lead screw, re-use current part.

  18. BOM • EE BOM presented at systems design review • ME BOM • Jig plate • L-Brackets • 10mm thick steel • Bearings • Motor coupler • Delrin/aluminum • Graphite brush

  19. LabVIEW State Diagram

  20. X X X X X X X

  21. Action Items = Busy Week • Obtain wireless PCI card from John Wellin. • Make computer functional for LabVIEW code. • Further follow-up with Rob Kraynik on concept feasibility. • Finish CAD parts: ESV guide, PR shaft key, motor shaft collars. • Create part drawings. • Create ME Bill of Materials. • Further review Risk Assessment.
