摘要： A module, included in an electrophotographic printer, for making toner images by a method in which transfer current for electrostatic transfer of toner images to receiver members is adjusted to compensate for ambient variations of toner charge-to-mass ratio (q/m). A predetermined functional relationship between transfer current and a control voltage parameter is utilized. Magnitudes of the control voltage parameter are derived from voltage measurements relating to creation of toner control patches on a photoconductive image-recording member included in a modular electrophotographic printer. Control voltage magnitude is linearly dependent on q/m. The functional relationship, which is characterized by three experimentally determined parameters, is co-optimized for providing efficient transfer of toner images and for minimizing back-transfer of toner away from a receiver member in a transfer station included in the module.

摘要： An electrostatographic reproduction apparatus includes: a primary imaging member for producing an electrostatic latent image on a receiver, a development station for applying toner particles to the latent image to form a developed toner image on the receiver, a fuser assembly for fixing the developed toner image to form a fused toner image on the receiver, and a transport member for transporting the receiver to or from the fuser assembly. The transport member includes a substrate and an oil-absorbing layer that contains inorganic particles dispersed in an organic binder and is capable of absorbing release oil applied to the receiver bearing the fused toner image.

摘要： Preventing the imaging forming process of an electrostatographic reproduction apparatus having a plurality of imaging modules in tandem relative to a receiver transport belt moveable along a transport path from becoming contaminated with fuser release oil. A substantially uniform layer of the pigmented marking particles from the development subsystem of the image forming process is deposited onto the photoconductive member of the image forming process during any non-imaging cycles of the process, including cycle down, non-imaging skip frames, or recovery from a receiver jam. The substantially uniform layer of pigmented marking particles acts as a barrier to block fuser release oil from the photoconductive member and as a vehicle to carry away contaminating fuser release oil.

摘要： A toner image is transferred from an image member to a receiving sheet using a backing member or corona charger to which a constant current source is applied for creation of a transfer electrical field. A logic and control receives an input indicative of the width of the receiving sheet and adjusts the current applied by the constant current source accordingly. Preferably, the logic and control also has an input indicative of the resistance of the receiving sheet, for example, determined by determining relative humidity and/or the thickness of the receiving sheet, which also is used with the width input to adjust the current applied by the constant current source.

摘要： An ion projection print head for applying ions line-by-line from a substantially uniform linear ion source, in a modulated pattern to a moving ion receptor substrate to form a latent image charge pattern on such substrate corresponding to information to be reproduced. The ion projection print head comprises a substantially planar mask having an elongated slot defined therethrough, the slot being oriented in a longitudinal direction substantially parallel to an element of the ion receptor substrate transverse to the direction of movement of such substrate. A continuous electrode is formed on the side of the mask between the mask and the ion source, and a plurality of electrodes are formed on the side of the mask opposite from the continuous electrode. The plurality of electrodes are spaced apart in insulating relationship from one another and terminate at the slot. An electrical bias is selectively applied to the plurality of electrodes respectively to modulate ion flow through the slot from the ion source to the receptor substrate.
