    摘要: This invention provides an image-forming machine with a pulse densitometer that avoids the formation of artifacts on electrophotographic films. The image-forming machine may have a charger, an exposure machine, a toning station, a transfer charger, a fusing station, and a densitometer positioned next to a photoconductor. The densitometer may have an emitter, a collector, and a pulse apparatus. The densitometer provides one or more pulses to measure the toner and photoconductor densities. The pulsed emissions are essentially below the exposure threshold of electrophotographic films, especially those sensitive to the infrared spectral region.

    摘要: A simple and economical method and apparatus for identifying the toner installed in a multi-toner printer by identifying the toner holder installed in the printer is disclosed. Additionally, the multi-toner printer is controlled based on the toner holder installed and a job selection. A toner identification apparatus comprising a toner identification module, a display device, and an input device, identifies the toner holder installed in a multi-toner printer by producing and identifying a unique voltage identification signal for the installed toner holder. A job selection algorithm determines whether the installed toner holder is the correct toner holder for a specified job selection. Additionally, if the toner holder installed in the multi-toner printer contains MICR toner, the job selection algorithm mandates a security procedure that must be carried out in order for printing to be allowed. In response to the job selection algorithm, the toner identification apparatus creates a control signal that instructs a control device of a multi-toner printer whether to allow a selected print job.

    摘要: A mechanism and process for detecting mottle or banding in a developed electrophotographic image. Within an electrophotographic reproduction apparatus 10, a photoconductor is used for receiving and developing a latent image. The photoconductor traverses a path that passes a charging station 28, an exposure station 34, a toning station 38, and a transfer station 46. Either a densitometer 76 for measuring the density of the developed image on the photoconductor, or an electrometer 50a or 50b for detecting the voltage of the image on the photoconductor, detects mottle or banding on the developed image. The densitometer 76 or electrometer 50a or 50b has an aperture small enough to detect mottle or banding with wavelengths perceptible by human eyes. A logic and control unit 24 averages the image density or voltage measurements, calculates the variations of the measurements about the average and the periodicities of the measurements, and if the variations or periodicities indicate mottle or banding is present, changes the operation of one or more stations to reduce mottle or banding.

    摘要: Modification of process control signals so as to enable electrostatographic reproduction apparatus, including a dielectric support member transported about a path into operative association with electrographic process elements to form an information reproduction on a receiver member and a process controller for receiving and sending appropriate timing control signals in an expected value range for controlling the electrographic process, to operate over an alternate process range. For the desired signal modification, an input signal in a particular value range is received. A predetermined gain is applied to the received signal, and thereafter a predetermined offset is applied to the signal as modified by the gain application. The signal derived by gain application and offset is then emitted at an alternate value range to effect process control.

    摘要: An electrophotographic machine includes a dielectric member configured for carrying a toner image. A transfer roller engages the dielectric member and transfers the toner image to an image substrate. A transfer roller power supply biases and periodically reverse biases the transfer roller. A transfer roller cleaning brush having conductive bristles engages the transfer roller. An electrically conductive brush housing encloses the transfer roller cleaning brush and defines an opening through which the bristles contact the transfer roller. The brush housing is electrically charged to the same electrical potential as said transfer roller and is selectively discharged.
