Abstract: A single pass tri-level imaging apparatus and method. Compensation for the effects of dark decay on the background voltage, VMod, and the color toner patch, Vtc readings is provided using two ESVs (ESV1 and ESV2), the former located prior to the color or DAD housing (58) and the latter after it. Since the CAD and black toner patch voltages are measured (using ESV2) after dark decay and CAD voltage loss have occurred, no compensation for these readings is required. The DAD image voltage suffers little dark decay change over the life of the photoreceptor (P/R) so the average dark decay can be built into the voltage target.

Abstract: IMPROVED DEVELOPING APPARATUS If developer within a xerographic developing apparatus becomes excessively charged, excessive toner is added to the apparatus because the excessively charged developer prevents a sensor from sensing the actual toner density within the apparatus. To overcome this problem, an element (contacted by the developer during movement of the latter within the apparatus) is connected to ground through a surge voltage protector. This prevents both the element and the developer from being excessively charged.

Abstract: A pair of Electronic Voltmeters (ESV) are utilized to control the P/R charging voltage in a Tri-Level imaging apparatus. One of the ESVs is used to control the voltage increases of a charging device. The other ESV is used to monitor the charge level of the charged area image of a Tri-Level image. When a critical value is sensed the control of the charging device is shifted to the ESV that monitors the charged area image level and limits the output from the charging device to a predetermined target value..
