Abstract

With reference to the Figure, a printer plotter prints a page instead of the more standard typewriter carriage approach. In particular, an X scan motor 10 and a Y scan motor 12 move the grinthead and/or input scanner device 14 in both the X and Y directions. This approach provides a more accurate means to move the printhead in both the X and Y directions The accuracy is necessary in order to "stitch" consecutive passes in the slower Y scan direction.

BUBBLE JET PRINTER/SMART COPIER (Cont'd)

With reference to the Figure, a printer plotter prints a page instead of the more standard typewriter carriage approach. In particular, an X scan motor 10 and a Y scan motor 12 move the grinthead and/or input scanner device 14 in both the X and Y directions. This approach provides a more accurate means to move the printhead in both the X and Y directions The accuracy is necessary in order to "stitch" consecutive passes in the slower Y scan direction.

The printer plotter uses a 48 dot printhead and is not capable of printing on a diagonal. It is proposed that an input scanner, (a charge coupled device, a simple optical feedback device, or any of a variety known input scanner technologies) be added to provide a copier/printer capability. For this approach, a 48 input (on .003" centers) scanner is chosen to match the printhead, but any size linear array can be used.

It is further proposed that appropriate electronics be added to permit at least a full page of storage (bit mapped OF otherwise) to allow image manipulation and/or enhancements. In this proposal, an original is placed on top of the paper tray 16 and via an operator input, a scanning of the original takes place. At each...
