摘要： A heat and pressure fuser for fixing toner images to substrates. A dual heating lamp arrangement is utilized for elevating the surface temperature of a heated fuser roll. The operation of the dual heat lamps is controlled using dual thermistors for maintain steady state temperature fluctuations to .+-.3.degree. F. The thermistors are positioned, one adjacent the inboard end of the fuse and the other adjacent the outboard end thereof. The outboard thermistor is used to determine the desired on time of the fuser lamp and the inboard thermistor is used to determine which of the two lamps is on. If the inboard temperature is below a predetermined target value a 14 inch lamp is turned on. If the inboard temperature is at or above a predetermined target value an 11 inch lamp is turned.

摘要： An online printing parameter establishment apparatus is used with a xerographic printing device for printing high quality prints given a target value. The xerographic printing device is capable of producing at least one print control patch on a photoreceptor and is capable of sensing a value of the at least one print control patch. The xerographic printing device has a plurality of sets of inherent performance characteristic values. The online printing parameter establishment apparatus includes a controller device and a switch device. The controller device is operative to produce a first database of different ones of the sensed values. Each sensed value is associated with a respective one of the plurality of sets of inherent performance characteristic values based upon the target value. The controller device is also operative to produce a second database of a plurality of control values. Each one of the control values is extracted from a respective one of the sensed values and the associated set of inherent performance characteristic values. Further, the controller device selects one of the control values which is closely comparable to the target value. A method for online establishment of print control parameters to render high quality prints using a xerographic printing process is also described.

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： An apparatus in which a latent image recorded on a member is developed with a developer material comprising at least carrier granules and toner particles. Toner particles are dispensed into the developer housing and mixed with unused developer material. The toner particles and developer material are advanced along an extended path so that the toner particles are gently mixed and triboelectrically charged to substantially the nominal level prior to contacting the latent image. A system of this type is particularly useful for toner particles requiring extensive gentle mixing to achieve the desired triboelectric charge.

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.

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.
