摘要： A method for reducing electromagnetic emissions in an electronic device having a multiple micro-controllers includes identifying the number of micro-controllers installed in the electronic device. An operating frequency range of the electronic device is determined based on the operating frequency range of each micro-controller. A frequency spacing for each micro-controller within the operating frequency range of the electronic device is then calculated, and an operating frequency is assigned to each micro-controller. The operating frequency of each micro-controller is separated from the operating frequency of each other micro-controller by at least the frequency spacing. Then, the operating frequency of each micro-controller is set at the assigned operating frequency.

摘要： A rotary encoder error compensation system for use in a marking device with a rotary encoder includes an error correction logic circuit and an error correction table linked to the error correction logic circuit. The rotary encoder is configured to generate an encoder signal indicating a detected position of a rotating element and has a known rotary encoder error. The error correction logic circuit receives the encoder signal from the rotary encoder. The error correction table includes normalized error correction values. The error correction logic circuit accesses the error correction table based on the detected position of the rotating element and the known rotary encoder error and obtains one of the normalized error correction values corresponding to the detected position of the rotating element and the known rotary encoder error.

摘要： A method and system for correcting paper registration skew. A skew or paper registration error of a sheet moving in a feed path is detected. A coarse adjustment, or copy paper registration, using full steps is performed until the registration error is reduced to a minimum value, below a full step. The frequency of one motor with respect to the other, or a reference, or reference motors, is adjusted for a fixed period to enable a fine adjustment to correct the registration error.

摘要： The present invention is a method and apparatus for monitoring the linear displacement of a body using a pair of ultrasonic transducers, one for transmitting an ultrasonic signal and one for receiving the ultrasonic signal. For example, the present invention may be used for monitoring the position of a stapling device relative to a set of copy sheets. The position monitoring system senses the linear position of the stapling device by measuring the time delay required for the ultrasonic signal to propagate from the transmitting transducer, located on a stationary reference, and the receiving transducer, operatively attached to the movable stapling device. The time delay is determined as a function of both a partial signal period and an integral number of complete signal periods for the ultrasonic signal. Moreover, because the frequency of the ultrasonic signal may exceed the resolution of a microcontroller used to monitor the position, frequency dividers are used to reduce the signal frequencies to measurable levels without impacting the performance of the position monitoring system.

摘要： What is disclosed is a novel system and method for determining real-time performance in a sub-assembly device that is driven by a dc motor. In one example embodiment, an electric motor is energized such that a sub-assembly driven by the motor achieves a target operating speed. Pulse width modulation data is captured and plotted along a time axis. A time duration when the sub-assembly device ended a startup operation and achieved a steady state operation is determined. A portion of the plotted data is then compared to an ideal plot defined for that sub-assembly device. Based on the result of that comparison, a determination is made whether the sub-assembly device is performing within accepted operational parameters. A maintenance operation is signaled to be performed in response to the determined sub-assembly operational performance. The data is stored in a historical database from which a preventative maintenance schedule can be derived.

摘要： A system and method electronically determines an edge of a copy substrate to be printed on. A copy substrate is inserted between a linear light source array and a linear sensor array and a light segment of the linear light source array is illuminated. An edge location of a shadow created by the copy substrate intersecting a light path between the illuminated light segment and the linear sensor array is measured, and a location of the edge of the copy substrate is calculated based on the measured shadow location. A second light segment of the linear light source on an opposite side of an expected copy substrate edge position of the light segment can also be illuminated, and a second edge location of a shadow created by the copy substrate intersecting a light path between the illuminated second light segment and the linear sensor array can be measured wherein this second measurement can be used with the first to calculate a location of the edge of the copy substrate. Alternatively, the calculated location can be used to determine a light segment of the linear light source which corresponds to the calculated location. This determined light source is illuminated and the shadow measured. The new measurement is used to calculate the edge of the copy substrate.
