Abstract: The invention relates to a surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt or a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

Abstract: A system to combine the transfer and fixing xerographic steps of a xerographic printer into one, as well as to eliminate the need for an electrical field for transfer. The image is transfixed directly from a photoconductor to the paper or other suitable substrate. Appropriate pressure is applied during this step to cold-pressure fix the toner on the paper, taking into account the type of substrate and type of toner. The cold pressure transfix can be done either directly from a photoreceptor, without an intermediate transfer belt (ITB), eliminating all electrostatic transfer subsystems and a fusing operation. Alternatively, for engines with an intermediate transfer belt (ITB), the cold pressure transfix could replace a needed second transfer and fuser system.

Abstract: A continuous-sheet printing tandem electrophotography system for printing a continuous sheet includes first and second electrophotography units. A first size of the continuous sheet is measured before an image printed by the first electrophotography unit with a first parameter value is fused on the continuous sheet. A second size of the continuous sheet is measured after the image printed by the first electrophotography unit is fused on the continuous sheet. The second electrophotography unit then prints the continuous sheet with a second parameter value that is determined by a size difference between the first and the second sizes. The first and the second sizes include a page length and a page width of the continuous sheet. The parameter values include a print speed, a polygon mirror rotating speed, a video clock frequency, and a laser power.
