Abstract: Methods and Systems for reminding about print history use an approach in which one or more conditions, such as print job name and/or file size, of a subsequently submitted print job are monitored to determine if the one or more conditions of the subsequent print job is substantially similar to a corresponding one or more conditions of a previous print job. A reminder message is displayed on a user interface if such a similarity so determined, and in response, a user can enter a selection of an option in the reminder message to handle the reminder message and/or control print processing of the subsequent and/or previous print job. The reminder messaging can be pre-configured and turned off, as required.

Abstract: A web cleaning system for a fuser system includes a web which is biased into contact with a rotating cylindrical member, such as a fuser roll, as the fuser roll is rotated about its axis of rotation. A lateral displacement system displaces the web, relative to the cylindrical member, in a direction parallel to the axis of rotation of the cylindrical member. In this way, regions of the web which have become contaminated with collected toner are shifted laterally, thus avoiding oversaturation of the web.

Abstract: A toner repelling stripper finger assembly is provided for stripping toner image carrying copy sheets from an outer surface of a moving heated fusing member. The toner repelling stripper finger assembly includes (a) a finger shaft having a first end for attaching to a baffle, and a second distal end; (c) an electrically conductive tip located at the second distal end of the finger shaft for contacting the outer surface of the moving heated fusing member to strip the toner image carrying copy sheets therefrom; and (d) an electrical biasing source connected to the electrically conductive tip for electrically biasing the electrically conductive tip to a desired electrical polarity, thereby repelling and preventing charged toner particles from being attracted and building up on the stripper finger assembly.

Abstract: A fuser apparatus includes first and second rolls rotatably mounted parallel to and in contact with each other to form a nip through which print media with a toner image thereon is passed to fuse the image to the print media. A cleaning system is provided for cleaning one of the rolls, such as the fuser roll. The cleaning system includes a rotatably mounted cleaning roll, an outer surface thereof including a pile. A flicker bar is arranged to detach toner from the pile.

Abstract: A roll useful in fusing marking material to a print sheet includes a coating disposed on at least a portion of the inner surface thereof. A lamp disposed inside the roll supplies radiant energy to the inner surface. The coating changes its absorptivity (such as color) as desired, to obtain specific desired temperatures at different portions of the roll. The coating can be thermochromic, changing its absorptivity in response to local temperature; or electrochromic, changing its absorptivity in response to an external electrical stimulus.

Abstract: A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. Two heating elements heat the fuser roll. One of the heating elements is configured for heating a first portion of the fuser roll while a second of the heating elements is configured for heating a second portion of the fuser roll. The second portion of the fuser roll is axially spaced from the first portion. A temperature sensing system monitors a temperature of the fuser roll in a first location and monitors a temperature of the fuser roll in a second location which is axially spaced from the first location. A control system determines an amount of power to supply to the first heating element as a function of the monitored temperatures at the first and second axially spaced locations and determines an amount of power to supply to the second heating element as a function of the monitored temperatures at the first and second axially spaced locations.

Abstract: In accordance with one aspect of the present exemplary embodiment, a system marks a document that comprises a processing component that at least one of copies, prints, faxes, configures imaging, staples, collates and hole punches a document. A marking component produces one or more marks on a document received from the processing component. A configuration component allows configuration of the marking component.

Abstract: A fuser system includes first and second nip rolls, rotably mounted parallel to and in contact with each other to form a nip through which print media with a toner image thereon is passed to fuse the image to the print media. A cleaning web system is provided for cleaning one of the nip rolls of unfused toner. The cleaning web system includes first and second rotatable web rolls. A web extends between the first and second web rolls and contacts the first nip roll. A drive system is operatively coupled with one or both of the first and second web rolls for advancing the web in a first direction and thereafter in a second direction opposite the first direction.

Abstract: A fusing apparatus includes a fuser roll and a pressure roll which define a nip therebetween. Two heating elements heat the fuser roll. One of the heating elements is configured for heating a first portion of the fuser roll while a second of the heating elements is configured for heating a second portion of the fuser roll. The second portion of the fuser roll is axially spaced from the first portion. A temperature sensing system monitors a temperature of the fuser roll in a first location and monitors a temperature of the fuser roll in a second location which is axially spaced from the first location. A control system determines an amount of power to supply to the first heating element as a function of the monitored temperatures at the first and second axially spaced locations and determines an amount of power to supply to the second heating element as a function of the monitored temperatures at the first and second axially spaced locations.

Abstract: An apparatus for fusing print sheets, such as in xerographic printing, comprises a heating element, and a temperature-sensitive mounting for the heating element. The mounting changes a position of the heating element over the course of use of the apparatus, thereby enabling a more efficient use of the heating element and emitted heat within the fusing apparatus.

Abstract: When powering up a xerographic fusing apparatus with two parallel lamps, power is applied to each lamp in a stair-step fashion, in which incremental increases in applied power for each lamp are staggered in time. This feature contributes to desirable anti-flicker effects of the whole apparatus.

Abstract: A fusing apparatus for xerographic printing includes a fuser roll with two parallel lamps, or heating elements, therein. At power-up, power is applied to each lamp in a stair-step fashion, in which incremental increases in applied power for each lamp are staggered in time. Also during power-up, the lamps are connected in series, but the series connection is removed for a running condition. These features contribute to desirable anti-flicker effects of the whole apparatus.
