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

Safety
Control limits hardcoded
into LabView Interface
for various voltages and
velocities
Educational Use
Interface and fixture
made easy to use with
documentation and
simple visual signals
LabView User Interface
-User interface allows for varying controls and data
acquisition
Functionality
Determined range of
power supply voltages,
carriage velocity, and
exposure times
Constructed dark
enclosure in order to
operate fixture in everyday
settings
Dark Enclosure
-Test fixture with dark enclosure attached in order to minimize
light sources
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
