摘要： Systems and methods for measuring and setting grid voltages in an image forming device may include setting a first charging device of a first image forming station to a first voltage level and setting a second charging device of the first image forming station to be off; charging a charge-retentive surface with the first charging device set at the first voltage level; measuring and the charge imparted to the charge-retentive surface by the first charging device; storing the measured charge value. Systems and methods may further include repeating the setting, charging, measuring and storing steps for the first charging device for at least one additional voltage level; and determining at least one parameter of the first charging device based on the stored measured charge values for the first charging device for each voltage level.

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： 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： 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： 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.

摘要： Toner patch generation for use in tri-level imaging is effected using a laser ROS. Two toner patches are formed using a single toner patch generator of the type commonly used in the prior art. The patch generator, used by itself serves to form one toner patch latent image and together with the ROS exposure device of the imaging apparatus is used to form the other toner patch latent image.

摘要： The Infra-Red Densitometer (IRD) readings of developed toner patches in a tri-level imaging apparatus are compared to target values stored in Non-Volatile Memory (NVM) and are also compared to the previous IRD reading. Toner dispensing decisions (i.e. addition or reduction) are based on both comparisons. In this manner, not only are IRD readings examined as to how far the reading is from the target, they are examined as to current trend (i.e. whether the reading is moving away from or toward the target). Thus, if the IRD reading indicates that the toner concentration is low but is heading toward the target then the amount of added toner is somewhat reduced. If the IRD reading indicates that the toner concentration is low and is heading away from target (getting lower) then some extra toner is dispensed

摘要： Photoreceptor charge control for obviating the adverse effects of photoreceptor variation inherent in the photoreceptor as the result of the manufacturing process. The voltage values around the periphery of the photoreceptor commonly referred to as the Vc belt signature are measured. The readings for each of the ESVs are averaged (to find the mean) and the deviations from the mean are smoothed using a 41-term weighting function that properly removes the high frequency reading spikes while retaining the low frequency belt signature. Center weighted averaging of 41 points (n, . . . n±20) where n is a measured point on the photoreceptor that is averaged with the previous twenty readings together with the next twenty readings is initiated a few mm past the photoreceptor seam and ends a few mm before the seam—no phase shift. The readings are taken approximately every 3 mm around the periphery of the photoreceptor.
