Abstract: A stripper for separating a print substrate from a fuser member in an electrostatographic printing machine has a substantially flat, thin, resiliently flexible finger-like member having a raised dimple-like bump adjacent one end of the finger-like member for contacting the print substrate when stripped from the fuser member, the finger-like member being coated on both sides with a smooth low surface energy film.

Abstract: An apparatus in which an image is fused to a sheet during a copy run. The number of sheets having images fused thereto is counted during the copy run. Heat is applied to at least the images of successive sheets of the copy run. The heat being applied to the images on successive sheets is controlled in response to the number of sheets counted.

Abstract: An apparatus in which an image on a sheet of support material is fused thereto. A fuser roller is arranged to contact the sheet of support material having the image to be fused thereon. The fuser roller has a heating element disposed internally and extending substantially along the longitudinal axis thereof. The heating element is asymmetrical with respect to a reference axis extending through the center of the fuser roller and normal to the longitudinal axis thereof.

Abstract: An apparatus in which images on sheets are fused during a copy run. Heat is applied to at least the images on successive sheets advanced, in seriatim, through a fusing device permanently affixing the images to the sheet. The temperature of the fusing device is detected and a signal indicative thereof transmitted. A controller compares the time derivative of the signal received from the detector at initialization of the copy run to a first constant and energize the heater of the fusing device when the first constant is less than the time derivative of the signal. During the copy run, after the time derivative of the signal is less than the first constant, the controller compares the signal received from the detector to a constant and generates an error signal indicative of the difference therebetween to control the heater of the fusing device.
