Mission Statement
Make existing test fixture operational
Integrate printer with user interface to allow full control of fixture and acquisition of data
Motivation
Fixture to be used for teaching purposes in courses based on xerography
Also for R&D
Main Customer Needs
Biggest concerns lie in safety, overall functionality of fixture, and affinity for being used to teach xerography in a classroom setting

Control limits hardcoded into LabView Interface
for various voltages and velocities
Functionality
Determined range of power supply voltages, carriage velocity, and exposure times
Constructed dark enclosure in order to operate fixture in everyday settings
Apply uniform

to paper
Educational Use
Interface and fixture made easy to use with documentation and simple visual signals
LabView User Interface
Dark Enclosure
Test fixture with dark enclosure attached in order to minimize light sources
User interface allows for varying controls and data acquisition
Dark Decay Test Data
Operability Testing
Looking for voltage drops in between ESVM’s, adequate dark decay under various settings, amount of toner on paper at end of xerographic process
Testing automated for the most part through the LabView interface
Allows for use of preset inputs and controls through .ini text files
Allows for recording of test results in tabled Excel format
Charge Substation Test Data
Results/Conclusions
Development of a user friendly computer interface
Increased functionality of existing test fixture
Building of dark enclosure to improve usability
