We use the Kaptzov's assumption  to determine boundary conditions on the surface of corona wire
: electric field strength on the surface [E.sub.(ro)] is proportional to the voltage below the corona onset [U.sub.0], and stays constant and equal to the initial field strength value [E.sub.0] determined from Peek's formula for U [greater than or equal to] [U.sub.0] .
A corona wire
roughly the thickness of a human hair pulls the toner from the drum by means of an electrical charge, and a wiper blade picks up any excess toner.
Comparison of data given in Table 1 and Table 2 show that the space charge reduces the field strength at the surface of corona wire
and increases it at the surface of plane electrode.
A second stream of gas is positively charged as it passes a high-voltage, platinum corona wire
. The charged gas collides with and transfers charges to the opposing stream of analyte particles.
This is because corona wires
and partial discharges in the transformer windings.
OmniVac is an internal air treatment system that removes toner dust from corona wires
, collecting it into a central filter.
