Abstract

Proposed is a system that can be used to convert flash based copiers 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 printer mode, but removed during the copier mode. In the printer mode, information is loaded into the LCD array, a page at a time, between exposure cycles. Once a LCD pixel is loaded, it remains in that state until reset.

PRINTER MODIFICATION FOR Proposed Classification FLASH BASED COPIER U.S. C1.355/232 Thomas J. Hammond Int. C1. G03g 15/04

Proposed is a system that can be used to convert flash based copiers 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 printer mode, but removed during the copier mode. In the printer mode, information is loaded into the LCD array, a page at a time, between exposure cycles. 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 sufficient resolution do exist and can be used to make full size LCD arrays of sufficient resolution.
