    摘要： A development unit used in xerographic printing retains a mixture of at least a first colorant and a second colorant. An illuminator directs toward at least a portion of the mixture a first light of one color, a second light of a second color, and a third light substantially outside of a visible range. A photosensor records a first reflectance signal based on light reflected from the mixture substantially in a visible range, and a second reflectance signal based on light reflected from the mixture substantially outside a visible range. The signals can be used to maintain the mixture at the desired total color and other properties.

    摘要： A lead edge and/or trail edge sheet curl sensing and constraint method and system. First and second light emitters and detector pairs are aligned such that the light beams from the first light emitter and second light emitter cross at the transport media sheet substrate path, which constitutes the path of a media sheet substrate with zero curl. A media sheet substrate with either positive or negative curl on the lead edge of the sheet substrate interrupts light beams from the first and second light emitters, as detected by first and second light detectors. A similar approach can be used to detect the trail edge curl. The time delay between the light beam interruptions is proportional to the sheet substrate curl, and the order of interruptions indicates whether the sheet substrate curl is positive or negative. A first pair and a second pair of substrate constraint rollers can also be provided in the paper path upstream and downstream of the sensing system. The roller pairs closest to the sensor are made of relatively non-deformable materials or of materials of similar elasticity so that different media are constrained in the sensor zone with the same sheet trajectory relative to the nip.

    摘要： In color printing with a color registration system for the registration of plural color images on an image bearing surface, such as a photoreceptor belt of a color printer, chevron shaped registration marks are imaged on the image bearing surface, which registration marks correspond to the color images and are sensed by a registration marks sensor as the image bearing surface moves in its process direction. The registration marks sensor has chevron shaped optical sensing areas provided by a matching pair of spaced apart elongated bi-cell detectors in a generally chevron shaped pattern. Each of these spaced apart elongated bi-cell detectors has a parallelogram shaped optical sensing area. That parallelogram shaped sensing area is defined by elongated parallelogram sides extending at the same angle as one leg of the chevron shaped registration marks, and parallelogram ends which are parallel to the process direction, so as to provide higher color registration accuracy.

    摘要： Method and apparatus for controlling amplifier gain, e.g., as used in ESV of a xerographic copier, has a light source, e.g., an LED, optically coupled to a gain control light dependent resistor (LDR). The LDR can be in a negative feedback loop around an amplifier. There is a voltage sensing probe located near the photoreceptor belt of the copier and coupled to an input of the amplifier.

    摘要： In accordance with the present invention a toner concentration and temperature sensing apparatus is provided for use with a developer container adapted to retain a quantity of developer material, the developer material including varying concentrations of magnetic carrier material and toner material. The toner sensing apparatus includes a micro controller device for controlling a sensing head to selectively generate a magnetic field within the developer container according to a first set of parameters stored in the micro controller. A preselected portion of the developer material is compressed by the magnetic field and a signal is generated across the sensing device and determining the resistance thereof. The signal across the sensing device varies as a function of the concentration of the toner. The micro controller converts the observed signal into a toner concentration value based on a second set of stored parameters. The developer temperature is obtained by measuring a voltage across a coil comprising the sensing device. The change in coil resistance is a linear function of developer temperature.

    摘要： An electrostatic measuring apparatus for measuring unknowns such as the electrostatic potential of a surface in a non-contacting manner, including a tuning fork and a sensing electrode, and in which the frequencies of two different vibration modes of the fork are separated by a slotted supporting structure which is united with the fork, and in which harmful amplitudes of vibration of the fork are avoided by an amplitude limiting structure integral with the sensing electrode. The amplitude limiting structure includes arms extending around the ends of the tines.
