T.Assistant: Hutchison, Kenneth C. Attorney, Agent or FirmAbstractImaging apparatus which employs MANIFOLD imaging techniques and reusable loops to create a marking material image and transfer it to a receiving medium. The apparatus may be employed in a printer having keyboard input and an elongate platen supporting a receiving medium along which the imaging apparatus moves, in which individual characters are projected from a character disc through a fracturable layer onto a dielectric web, from which the images are transferred subsequently to the receiving medium by a retractable transfer member.The apparatus may be employed in a printer having keyboard input and an elongate platen supporting a receiving medium along which the imaging apparatus moves, in which individual characters are projected from a character disc through a fracturable layer onto a dielectric web, from which the images are transferred subsequently to the receiving medium by a retractable transfer member. | |
