Abstract

Proposed is a system that can be used to convert flash based copiers with facsimile into printers without losing the copy function. 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 during the print mode of the facsimile (fax) function cycle, but removed during the copier mode. In the fax mode, information is received or scanned by a separate fax unit. In the fax print mode, information is loaded into the LCD array a page at the time as it is received by the fax unit. 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 with facsimile into printers without losing the copy function. 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 during the print mode of the facsimile (fax) function cycle, but removed during the copier mode. In the fax mode, information is received or scanned by a separate fax unit. In the fax print mode, information is loaded into the LCD array a page at the time as it is received by the fax unit. 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. The fax function and copy function remain independent. Present LCD array technology has sufficient resolution to be used with fax transmissions.
