Abstract: 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.

Abstract: The invention relates to a device and method for treating the surface of an article in connection with printing. More particularly, the invention relates to a method and device, which is capable of checking the motion of a roller in a device for fixing toner on printed sheet or web material using a magnet and a magnetic sensitive element located in a fixed position near the rotating element so as to sense the passage of at least a pole thereof at each rotation of the magnet.

Abstract: A toner level detector assembly includes an electrically conductive container body that defines a container cavity and an orifice. A sensor assembly includes a holder and a probe. The holder is sealingly associated with the orifice. The probe is disposed within the holder. The holder electrically isolates the probe from the container body. The probe senses a level of material within the container cavity.

Abstract: The invention provides a diagnostic system for a densitometer in an image-forming machine. An image-forming machine with a densitometer diagnostic system may have a photoconductor, one or more chargers, an exposure machine, a toning station, and a densitometer. A densitometer diagnostic system for an image-forming machine may have an emitter, a collector, amplifier circuitry, and diagnostic circuitry. The diagnostic circuitry reduces the drive current to the emitter in the densitometer by a known or calculable value. The output voltage from the amplifier circuitry in the densitometer is reduced in proportion to the reduction in the drive current. To perform diagnostic testing of the densitometer, a first output voltage is obtained from the densitometer without the diagnostic circuitry connected. A second output voltage is obtained from the densitometer with the diagnostic circuitry connected.

Abstract: Electrostatographic recording method and apparatus that includes a primary image-forming member (PIFM) which moves along a closed path at high-speed. The PIFM may be in the form of an endless belt, which has a row of image frame synchronizing indicia. The indicia are spaced from each other in the direction of movement of the PIFM. The indicia are not all uniformly spaced from one another so that an interframe area larger than other smaller interframe areas on the PIFM can exist. During a production run toner images are formed on the image frames by sensing the image frame synchronizing indicia. The larger interframe area is provided preferably at a splice or seam area to provide sufficient time for a change in a process element for which sufficient time is not available at a smaller interframe area.

Abstract: An electrostatographic recording apparatus includes an endless recording member upon which toner images are recorded. A densitometer is provided for measuring density of a toned area on the recording member. The densitometer includes a light emitting and/or light sensitive component that is located in an internal space confined by the endless recording member. The densitometer further includes a slidable support upon which the component is mounted in facing relationship with and proximate to an internal facing portion of the recording member. A stationary mounting structure is attached to a film core upon which the film-like recording member is supported. The slidable support is received within the stationary mounting structure. An electrical circuit is electrically connected to the component and is mounted on a side of the slidable support that is opposite in facing direction to that of the component.
