Abstract
A sheet transport apparatus for transporting an image carrying sheet into a fusing apparatus without image disturbances from a sheet motion opposing force. The sheet transport apparatus includes a baffle plate positioned along a line of sheet movement into the fusing apparatus, and active means for moving the image carrying sheet over and towards the baffle plate. The sheet transport apparatus also includes a generally triangular member having a flat base positioned on the baffle plate, and an upstream flank as well as a downstream flank forming an apex thereof for creating a convex buckle in the image carrying sheet prior to the image carrying sheet being subjected to a sheet motion opposing force from contact with the fusing apparatus.

A reproduction machine comprising:
- (a) means for forming and transferring a toner image onto an image-side of an image carrying sheet;
- (b) a fusing apparatus for contacting the image carrying sheet to fuse the toner image thereonto;
- and
- (c) a generally triangular buckling device for preventing smearing of the toner image on the image carrying sheet by gravitationally creating an image-side convex buckle in the image carrying sheet prior to contact between the image carrying sheet and said fusing apparatus, said generally triangular buckling device including a downstream declining flank for gravitationally supporting the image carrying sheet into contact with said fusing apparatus.
In a reproduction machine including a fusing apparatus and means for forming and transferring a toner image onto an image carrying sheet, a sheet transport apparatus for transporting the image carrying sheet into the fusing apparatus without image disturbances from a sheet motion opposing force, the sheet transport apparatus comprising:
- (a) a baffle plate positioned along a line of sheet movement into the fusing apparatus;
- (b) belt and vacuum active means for moving the image carrying sheet towards said baffle plate;
- and
- (c) a separate and generally triangular member having a flat base positioned on said baffle plate, and having an upstream flank and a downstream flank both forming an apex thereof for gravitationally creating a convex buckle in the image carrying sheet prior to the image carrying sheet being subjected to a sheet motion opposing force from contact with the fusing apparatus.
