Patent number: 6097912Abstract: Disclosed is a protective cover package for an endless, organic photoreceptor belt of an electrophotographic printer. The protective cover package is a flexible, closed loop sheet member which extends about an outer, photoreceptor coated surface of the endless belt. The photoreceptor coated surface of the endless belt is releasably secured to an inner surface of the sheet member, such that the sheet member supports the belt, and protects the photoreceptor surface from damage that would adversely affect the image reproduction quality of the belt. The sheet member has a belt loading configuration, that substantially duplicates the configuration of the endless belt when the belt is mounted onto support rollers of the electrophotographic printer. By replicating the configuration of the support rollers, loading of the belt onto the rollers is facilitated using the protective cover package. The sheet member also has a compact configuration that requires less volume than the belt loading configuration.Type: GrantFiled: December 10, 1998Date of Patent: August 1, 2000Assignee: Imation Corp.Inventors: John D. Watson, Henry C. Gydesen, James E. Zenk, Donald J. Goetzke, Bruce W. Carlson, Claire A. Jalbert

Patent number: 5976698Abstract: Process and materials are described for selectively placing uniform spacers on a receptor. Spacer elements are placed on a receptor by selectively irradiating a thermal transfer donor sheet comprising a transferable spacer layer. The transferable spacer layer may include particles or fibers to form a composite. The particles may have a spacing dimension either greater than or less than the thickness of the transferable layer. When the spacing dimension of the particle is greater than the thickness of the transferable layer, then the spacing dimension of the particles control the spacing distance. The process and materials are useful in the manufacture of flat panel displays, particularly, liquid crystal display devices.Type: GrantFiled: September 24, 1997Date of Patent: November 2, 1999Assignee: 3M Innovative Properties CompanyInventors: John S.

Patent number: 5650253Abstract: Method and apparatus for producing an image on plain paper from image data using a photoreceptor. An image-wise distribution of charges is produced on the photoreceptor corresponding to the image data. A liquid ink having solid charged pigmented particles, the liquid ink having an effective glass transition temperature of less than 25 degrees Celsius is applied to the photoreceptor forming an image-wise distribution of the pigmented particles on the photoreceptor to form the image. The liquid ink has greater than seventy-five percent by volume fraction of solids in the image. A film forming means is positioned against the photoreceptor immediately following the application means to dry the image of the liquid ink to film forming within 0.5 seconds. The image is dried on the photoreceptor. The image is then transferred to an elastomeric transfer roller which forms a first transfer nip under pressure with the photoreceptor.Type: GrantFiled: September 29, 1995Date of Patent: July 22, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: James A.
