A system of automatically naming an electronic document may include a scanning device. The system may receive a physical document that is to be converted into an electronic document, perform optical character recognition on at least a portion of the physical document to identify one or more terms that are present in the physical document, and store the identified terms in the data store associated with the scanning device. The system may receive input from a user that includes one or more first characters and corresponds to a title of the electronic document. The system may identify one or more terms from the data store that correspond to the one or more first characters by querying the data store using the received input, and cause the identified terms to be displayed to the user via a display device of the scanning device as suggested document names for the electronic document.

Methods and systems for automatically generating a name for an electronic document

A method, non-transitory computer readable medium, and apparatus for aligning a bias transfer roll are disclosed. For example, the method detects a position of a paper, determines a position of the bias transfer roll, calculates an offset between the position of the paper and the position of the bias transfer roll and moves the bias transfer roll laterally by an amount of the offset to align the bias transfer roll to the paper.

A temperature monitoring system for a media heater of an imaging device comprises a temperature indicator overlying a surface of a media heater of an imaging device. The temperature indicator is configured to vary an optical property in response to changes in temperature at the surface of the media heater. The system includes an optical scanner for scanning the temperature indicator to detect the optical quality. The optical scanner is configured to generate a signal corresponding to the detected optical property.

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.

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.

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.

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.

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.

Multivariate predictive control of fuser temperatures

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.

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.
