NOTE: This adjustment must be performed in
the exact order presented here.
PURPOSE
The purpose of this adjustment i s to obtain
good copy quality by bringing the corotron
and exposure voltages to their required
specification.
1. Before performing this procedure check
the following:

electrometer probe and the probe
holder. If the
fit is
too loose the
probe will rotate in the holder
during the procedure, and cause an
inaccurate adjustment. Do not
continue the adjustment until this
condition i s corrected.
the battery of the DMM i s not at

energized.
the 2 VDC scale is selected on the
DMM.
the low battery LED

not
illuminated on the electrometer.
the chivgc c~rotron is
serrted
correctly.
NOTE: When the electrostatic series i s
completed with
