  • Patent number: 5737669
    Abstract: A band printer having a transport mechanism, an endless photoreceptive image carrying ribbon, a latent toner imaging apparatus, a transfer mechanism, and a fixing mechanism is disclosed. The transport mechanism defines a printing medium path extending in a first direction and transports a printing medium along the printing medium path. The endless photoreceptive image carrying ribbon circulates adjacent the printing medium path in a second direction at an angle to the first direction, and the latent toner imaging apparatus is adjacent to and stationary with respect to the circulating ribbon. The imaging apparatus forms an electrostatic latent toner image on the surface of the ribbon according to received image data as the ribbon moves past the imaging apparatus, and the transfer mechanism transfers the formed toner image to the printing medium when the formed toner image is aligned with the printing medium. Thereafter, the fixing mechanism fixes the image to the printing medium.
