Abstract

Proposed is a system that can be used to convert flash based copiers into Electronic Reproduction (ER) copiers that retain the copy quality and motion quality of flash based copiers but gains the advantage of electronic input and editing. A full frame (full platen) reflective mode (no back light) Liquid Crystal Display (LCD) array is added to the copier in a configuration that allows the LCD to be positioned over the platen. A Raster Input Scanner (RIS) and appropriate Electronic Subsystem (ESS) are also added to the system. In the copy mode, a document is scanned by the RIS and the information is processed by the ESS and loaded into the LCD array a page at a time. Once a LCD pixel is loaded, it remains in that state until reset.

Proposed is a system that can be used to convert flash based copiers into Electronic Reproduction (ER) copiers that retain the copy quality and motion quality of flash based copiers but gains the advantage of electronic input and editing. A full frame (full platen) reflective mode (no back light) Liquid Crystal Display (LCD) array is added to the copier in a configuration that allows the LCD to be positioned over the platen. A Raster Input Scanner (RIS) and appropriate Electronic Subsystem (ESS) are also added to the system. In the copy mode, a document is scanned by the RIS and the information is processed by the ESS and loaded into the LCD array a page at a time. Once a LCD pixel is loaded, it remains in that state until reset.

Once the full LCD page is displayed, the copier lamps are flashed and the information shown on the LCD is imaged onto the photoreceptor just as if the

LCD were an input document on the platen. Present LCD array technology does not have sufficient density for high quality printer resolution. However, linear arrays with suMlcient resolution do exist and can be used to make full size LCD arrays of sufficient resolution.
