Jeff,
        Please don't be offended if the following discussion greatly
underestimates your expertise.  I am only trying to help.
        I am wondering how you arrived at the current capabilities of your
transformers.  The reason is that electrostatic copiers require high voltage
, but only for the production of corona.  The current requirements are so
low that a more normal rating would be 4 Milliamps.  I have 4 or 5 of these,
and none of them can provide enough current to adequately energize a
discharge tube (used to display the Crookes dark space, rough test for vacuum
, etc.).  These tubes only require about 10 milliamps.  Do you have a spec
plate on the transformer?  Please don't be insulted, I just would hate to
have you waste time building something with inadequate transformers!  It
is entirely possible that your copiers are something industrial that I am not 
familiar with, but even the office sized copiers do not have high power 
transformers.

Hoping for a legible specifications plate,

Jack
