Abstract
An electrostatographic reproduction apparatus transfers a toner image from an image member to a receiver sheet by applying an electric field between the image member and the receiver sheet in a direction urging the toner image to the receiver sheet. A programmed power supply is adapted to (1) generate a pre-set constant current across the applied electric field during an adjustment period and (2) lock onto the voltage that supplies the set-point current for the reminder of a reproduction run. The value of the voltage is used to automatically adjust the value of an least one electrostatographic process element. The electrostatographic process element to be adjusted may be at least one of detack bias, detack duration, initial voltage V.sub.0, exposure E.sub.0, developement bias V.sub.B, copy sheet conditioning, and copy sheet drying.
