Abstract
Apparatus and method for minimizing ghosting defects and process control instabilities for a printing system are disclosed. According to an exemplary embodiment, a controller retrieves uniformity measurements of an interdocument zone (IDZ) and sheet zone (SZ). In response to the uniformity measurements, a transfer current IDZ level is controlled to minimize differences in subsequent charging, photodischarge and/or development associated with the IDZ and SZ.
