A fixing system is provided including a rotatable fixing member and a pressure member arranged to form a fixing nip between them. The fixing member has a selected non-smooth surface that includes silicone. A release lubricant is applied to the fixing member. A fixing temperature and a fixing speed are selected based on the receiver surface type. The fixing member is heated to have a surface temperature substantially equal to the selected fixing temperature. The fixing member is rotated at the selected fixing speed to draw the toned receiver through the fixing nip, so that the toner is heated and fixed to the receiver and the resulting print has a matte finish.

Abstract: A circuit breaker panel for hazardous environments and, in particular, Class 1, Division 2 environments, includes a housing having an internal cavity and an access opening through which the internal cavity is accessed. A closure door covers the access opening of the housing. The closure door is held in a closed positioned solely by one or more one latches. This permits rapid access to be obtained to the internal cavity through the access opening. Electrical components are positioned within the internal cavity of the housing, some of the electrical components being circuit breakers. Each of the circuit breakers and all other arcing and sparking electrical component is enclosed in its own self contained explosion proof casing.

Abstract: An adaptive training system for use with an adaptive testing tool includes a user interface receptive of a field of application selection from a user. A plurality of task items are stored in a data store. The plurality of task items are organized by field of application and ranked by difficulty level. An adaptive item selector selects unfamiliar task items as training items based on the selected field of application and a user ability. These training items range in order of difficulty from items slightly below a user's ability to items sufficiently far above that level to allow for learning effects. The user ability is a function of previous user performance on an adaptive test in the selected field of application. The main purpose of the adaptive item selector is to ensure that training items are neither too easy nor too difficult for a person.

Abstract: In a reproduction apparatus having a logic and control unit, and a fuser assembly including a heated fuser roller and a sensor for sensing the temperature of such fuser roller by utilizing heat to change sensor resistance to provide an electrical signal corresponding to the fuser temperature, for the logic and control unit, a method for detecting erratic resistance in the temperature sensor. The method includes the steps of, at preselected time intervals, comparing a current temperature reading to a previous temperature reading, and determining if the temperature sensing system indicates that the temperature has changed by more than a predetermined amount based upon reproduction apparatus operating characteristics. If the temperature sensing system indicates, from the determining step, that the temperature has changed by more than a predetermined amount, an indication that an error has occurred is made.

Abstract: A mechanism for cleaning the surface of an operative element of a reproduction apparatus. The cleaning mechanism includes an elongated web of cleaning cloth material. A first support provides a supply of the elongated web of cleaning cloth material, and a second support provides a take-up for the elongated web of cleaning cloth material. A motor is operatively coupled to the second support to drive the second support for selectively advancing of the elongated web of cleaning cloth material from the first support to the second support to provide a clean portion of the elongated web of cleaning cloth material to clean the operative element. An encoder, associated with the motor, produces a string of pulses while the motor is operative to drive the second support. A logic and control unit produces a signal for turning the motor on for a period of time establishing a web advancement cycle where a given predetermined number of pulses in a pulse string are produced by the encoder.

The pressure sensing mechanism includes a pressure-sensing gauge operatively associated with the offset preventing oil delivery system. A pressure sensing circuit includes a pressure gauge port for converting detected pressure from the pressure-sensing gauge into a corresponding electrical signal. Responsive to the electrical signal, the pressure sensing circuit calculates a delta voltage between when the oil delivery system is operating and when the oil delivery system is not operating, and determines whether the delta voltage system is within a specific operating range. A logic and control unit, responsive to the electrical signal, monitors the electrical signal from the pressure sensing circuit to ensure that the offset preventing oil is being properly delivered to the oil delivery system.
