ABSTRACT:
A sheet handler for deskewing and registering sheets en route to a processing station in an image processing apparatus includes cross rolls that drive each copy sheet against a registration edge for deskewing purposes. The angle of a driven one of the cross rolls with respect to the registration edge is adjusted, as well as, its speed varied based on the output of a sheet weight detector to a controller that controls pivotal movement of the driven cross roll.
