摘要： A method and apparatus for a single densitometer design that is used for all colors within multiple color image processing system. The preferred embodiment employs an LED having a light adjustment mechanism for controlling the amount of light received by a light detector in the densitometer. The coarse light adjustment is provided through a variable aperture. Fine light adjustment is accomplished through controlling the current through the LED, either by a potentiometer or through an automated process. Preferably, each of the LEDs is selected by wavelength to maximize the absorption by the colorant yielding light roughly complimentary to the colorant. The adjustment circuit provides advantage in color printing systems by allowing duplicate versions of the same densitometer circuit to yield similar voltage outputs for different colorants, thereby compensating for different absorption characteristics and light output of different colored LEDs.

摘要： The present invention provides an electrophotographic (EP) image-forming machine and related method having activation of a charger cleaner in a corona charger after an arcing fault. The corona charger has corona wires connected to a high voltage potential supply, preferably providing a voltage in the range of about 5 to 11 kva or in the range of about 13,000 to 22,000 volts peak-to-peak. A corona voltage detection circuit is connected to measure current changes in the high voltage potential supply. A grid has a preselected electric potential to control the charge. The grid may be grounded, but preferably is connected to a power supply providing a voltage in the range of about 300 to 900 volts. A grid voltage detection circuit is connected to measure current changes in the power supply. The voltage detection circuits provide a voltage signal to a microprocessor. When arcing occurs, the microprocessor cycles the EP image-forming machine into a standby mode. The charger cleaning apparatus is activated to clean the charger. When the cleaning is completed, the EP image-forming machine returns to normal operation. In a further aspect of the present invention, the image-forming process stops when arcing occurs. The charger is cleaned. Any prints affected by the arcing are disposed. The image-forming process restarts at the image frame where the arc occurred.

摘要： A computer disk of the type having a central drive hub comprised at least in part of ferromagnetic metal to clamp the disk to a magnet spindle drive is provided with a ring-shaped amorphous ferromagnetic surveillance marker between the hub flange and the disk substrate. The hub metal has a high permeability, e.g. .gtoreq.2,000 to concentrate the drive magnet field in the hub, when the disk is in the disk drive, thereby to eliminate fringe fields that would magnetize the marker. This is to allow the use of a low magnetic field intensity sensor in the sensor to detect the presence of the marker to enable recording of data on the disk. The hub metal also has a coercivity between the coercivity of the marker and the intensity of the magnetic field employed in the interrogation zone of an area surveillance portal to eliminate the effect of any residual magnetism on the hub metal caused by the drive magnet thereby to enhance the detectability of the marker by the portal.

摘要： A development system (10) for an electrophotographic printer (100) with multiple augers and containing a development roller (11) and a first channel (12) containing a feed auger (13) and developer (14), where the magnetic strength of the feed pole of the development roller increases in the direction of developer flow (18) in the first channel. This increase in magnetic field strength of the feed pole (50) ensures that a uniform layer of developer is formed on the development roller despite the volume of developer in the first channel decreasing along the length of the first channel in the direction of developer flow.
