Abstract: A printer paper tray improper loading protection system which is automatically moved by the repositioning of a conventional repositionable stack edge guide to restrict improper loading of sheets into the area of the tray which is outside of the proper sheet stacking area for sheet feeding, even though that restricted area varies depending on the selected size of the sheets being properly loaded within the proper sheet stacking area. A customer warning and partial obstruction of the non-feeding restricted area of the tray eliminates confusion as to where the operator should load paper into the tray whenever the tray is accessed, no matter where the tray stack edge guides are positioned for different paper sizes. An accordion-folded, reeled, or other expandable and contractible member operatively connects between the repositionable stack edge guide and the opposite end of the tray, extending above the tray stacking surface therebetween.

Abstract: As the individual pages of a book having a gutter and outside edge margins and being held at least partially open are being automatically sequentially turned over, in coordination therewith a flattening force is applied to the unimaged gutter margin areas of the book for flattening the pages after they have been at least substantially turned over, and unimaged outside edge margins of the book are clamped by automatic clamping members in coordination therewith, for appropriate page viewing and/or imaging. The flattening force may be applied with a V shaped reciprocally movable member, which may also be partially self-centering in the book gutter, and may also open to push outwardly on the then-open pages, as applied.

Abstract: An electrostatographic reproduction machine including a controller to time multiplex the function of displaying visual information and scanning user input devices. The machine includes an input device, to generate a signal responsive to a user input, a user interface, including visually displayed information, to visually display machine operating states determined as function of the signal, and a controller, including a selection line, coupled to the user interface and to the input device, to select the user interface to display the visually displayed information and to cause the input device to generate signals responsive to the user input.
