ABSTRACT:
An improved coronode assembly includes pin guards that are positioned closely spaced from and extending above a coronode in order to provide protection for a user reaching past the coronode to remove a sheet jam, and prevent coronode damage when the coronode is handled during servicing by a field service technician. The closeness of the pin guards to the coronode also serves to produce a more uniform field.
