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

  29. Signal Processing and Flow

  30. Closer Look at the Motors • 9-Pin Connector from Motor to Voltage Supply • Requires isolating motor ground from voltage supply to aluminum substrate for the S83-93 • Indexer will be incorporated in the 2-Axis PCI Motor Controller • Speeds: • ESV Drive: Constant Speed • P/R Drive: Automatically adjusted via LabView according to P/R diameter input and desire speed input (<1 m/s)

  31. Motors Dimensions ESV Unit Drive: S57-51 Photoreceptor Drive: S83-93
