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
