摘要： In a single pass, tri-level imaging apparatus, machine cycle down is initiated when the color developer housing is functioning improperly. The voltage level of the color image prior to its development is read using an electrostatic voltmeter (ESV). The voltage level thereof is also read after development. The difference between these two readings is compared to an arbitrary target value and a machine cycle down is initiated if the difference is greater than the target.

摘要： A pair of Electronic Voltmeters (ESV) are utilized to control the photoreceptor 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.

摘要： Recalculation of electrostatic target values in a tri-level imaging apparatus are utilized to extend the useful life of the photoreceptor (P/R). The increase in residual voltage due to P/R aging which would normally necessitate P/R disposal is obviated by resetting the target voltage for the full ROS exposure when it reaches its exposure limit with current P/R conditions. All contrast voltage targets are then recalculated based on this new target.The new targets are calculated based on current capability of the overall system and the latitude is based on voltage instead of exposure.

摘要： A single pass tri-level imaging apparatus and method. Compensation for the effects of dark decay on the background voltage, V.sub.Mod, and the color toner patch, V.sub.tc readings is provided using two ESVs (ESV.sub.1 and ESV.sub.2), the former located prior to the color or DAD housing and the latter after it. Since the CAD and black toner patch voltages are measured (using ESV.sub.2) 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 P/R so the average dark decay can be built into the voltage target.

摘要： In order to shorten cycle up convergence, a stored or resident image is utilized. It is contained on an external control or pixel board forming a part of the machine image output terminal (IOT). The resident image together with a raster output scanner (ROS) is used to form two charge, V.sub.CAD, two discharge, V.sub.DAD and two background, V.sub.Mod patches in every frame for a total of six patches. A pair of electrostatic voltmeters (ESV) are used to read all six patches and control decisions are made on the basis of the average of the two readings for each voltage level.Because of their physical locations relative to the ROS the readings of one ESV are used in forming the two charge area patches while the other ESV is used in forming the discharge area images. Both ESVs are employed for forming the two background patches.

摘要： In a xerographic printer for tri-level highlight color imaging, two electrostatic voltmeters (ESVs) are used to interpolate the electrostatic potential at a particular location along the path of the photoreceptor belt. Anomalous ESV readings, such as would be caused by dirt interfering with the ESV itself as opposed to systemic changes in the whole apparatus, are detected by having the printer enter a "test mode" in which test patches having minimal charge are monitored by the ESVs. The low-charge test patches enable noise related directly to the ESVs to be isolated from other possible sources of noise. The noise which results from ESV malfunctioning is compensated for when the printer returns to operation.
摘要翻译：在用于三级高亮度彩色成像的静电印刷机中，使用两个静电电压表（ESV）来沿着感光带的路径在特定位置处插入静电电位。通过使打印机进入“测试模式”来检测异常的ESV读数，例如由于污染物与ESV本身的干扰而与整个设备的系统变化相反，ESV中的ESV检测具有最小电荷的测试贴片。低电荷测试贴片可使与ESV直接相关的噪声与其他可能的噪声源隔离。当打印机返回到操作时，会补偿由ESV故障引起的噪音。

摘要： Two sets of targets, one for use during cycle up convergence of electrostatics and one during runtime enable single pass cleaning of developed patches, during cycle up convergence. To this end, different targets from those used during runtime are used for the preclean, transfer and pretransfer dicorotrons during cycle up.Proper charging of the photoreceptor during runtime and cycle up convergence is also enabled by the provision of two charging targets, one for each mode of operation.
