Abstract
Abstract Apparatus for utilizing a single paper path for printing, copying, scanning, and sending and receiving facsimiles by combining a gear box assembly and an adjustable scan head assembly with a conventional printer. The invention contemplates a first position for scanning, copying, and sending facsimiles of an image, and a second position for printing, reproducing a copied image, and receiving facsimiles. In the first position, the path of a single sheet of paper is impeded by the scan head mechanism. In the second position, a sheet of paper onto which an image has been transferred by dot matrix, ink, or laser printing, can move through the multipurpose information transfer device unimpeded. The invention contemplates a single stationary path to which information transfer functions are added and taken away, instead of multiple paths to accommodate stationary information transfer functions.
