Abstract
A method of operating an electrostatographic printing apparatus, the apparatus including a charge-retentive member defining an imaging surface and a charging device for placing a charge on the imaging surface, a gap existing between the imaging surface and the charging device, including applying an electrical bias to the charge-retentive member by generating a burst modulated waveform.

A method of operating an electrostatographic printing apparatus, comprising:
- applying an electrical bias to a charge-retentive member of the electrostatographic printing apparatus, said charge-retentive member defining an image surface, the electrostatographic printing apparatus further including a charging device for placing a charge on the imaging surface, a gap existing between the imaging surface and the charging device, said applying including generating a burst modulated waveform.
A method of charging a charge-retentive member of an electrostatographic printing apparatus, comprising:
- applying an electrical bias from a charging member of the electrostatographic printing apparatus to an imaging surface of the charge-retentive member, a gap existing between the imaging surface and the charging device, said applying including generating a burst modulated waveform.
