摘要
In a xerographic development system in which an AC field is set up in a gap between a donor member and the photoreceptor to develop an electrostatic latent image, a series of tests are performed to ascertain that the width of the gap is within a suitable range. In test mode, various DC and AC biases associated with the field are systematically altered, and the reflectivities of resulting test images are read. Based on these reflectivity readings, it can be determined if the gap is too wide, such as to cause poor print quality, or too narrow, such as to cause arcing.
