Abstract
This invention is a scanning array for sequentially converting portions of an image of a document into digital format, a print head for sequentially printing those portions of the image onto a receiving means, logic circuitry interconnecting the scanning array and the print head, and a stepper motor connected to the scanning array and the print head to step the scanning array in a first direction while at the same time stepping the print head in a second direction. Control circuitry is also provided to enable the scanning array to scan in the first direction asynchronously with the print head printing the image in the second direction. A second stepper motor is included to index the copy sheet past the scanning array and the print head.
