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： A system, method, and apparatus for adjusting dry ink concentration in a developing station (30) of a printer is disclosed. The adjustment is performed by calculating the thermal drift of a dry ink monitor (40) and applying the result as a compensating factor in calculations in a software algorithm. The dry ink monitor (40) has a sensing port (42) in contact with a dry ink concentration and is connected to a dry ink monitor interface board (10) that houses a temperature sensor (20). The monitor interface board (10) is positioned in proximity to the dry ink monitor (40) to enable the temperature sensor (20) to measure a temperature of the dry ink concentration. The software algorithm is used to adjust the dry ink concentration based on a slope coefficient calculated by the printer based on outputs from the dry ink monitor (40) and the dry ink monitor interface board (10).

摘要： A method and apparatus for replenishing toner based on the electric current used over time by the exposure subsystem. Toner take-out for each image is estimated by measuring the current used by the exposure system, subtracting the quiescent current, integrating over a page or frame, and multiplying by a predetermined value that indicates the amount of toner required by the image, based on the average current used for the exposure and other process parameters. These calculations are done either in hardware or in software. The replenishment system is used to add the correct amount of toner to the developer station to maintain the toner concentration at an approximately constant aim value.

摘要： An electrostatographic reproduction apparatus having a transfer assembly, including an electrically biased transfer roller in nip relation with a dielectric support member, for effecting transfer of a pigmented marking particle image from an image area of a dielectric support member to a receiver member in transfer relation with the dielectric support member in the transfer nip, a mechanism for cleaning the transfer roller including a control for the electrical bias on the transfer roller. The electrical bias control has a power supply generating an electrical output, of a settable polarity, connected to the transfer roller for applying an electrical bias of a set polarity thereto. A mechanism disables the power supply for a period of time during a start-up phase of reproduction so as to prevent transfer of residual marking particles from the dielectric support member to the transfer roller.
