Abstract:
An electrostatic printer comprising,a linear supply of dimensionally variable, electrostatically printable, dielectric material movable in a lengthwise first directionan electrostatic writing head scanning in a widthwise direction, transverse to the lengthwise direction, during a time period to deposit an electrostatic latent image thereon anda motion sensor means, attached to said writing head for producing a plurality of pulses corresponding to the movement of said writing head,control circuitry means coupled to the motion sensor means, synchronized with said plurality of pulses corresponding to the movement of said writing head,means for advancing the supply of dielectric material in the lengthwise first direction,means for determining dimensional variations in said dielectric material due to environmental changes and producing signals corresponding thereto; anda charge deposition delay circuit in electrical communication with said writing head, said delay circuit being coupled to receive said signals and pulses to adjust said electrostatic latent image on said dielectric material in accordance with said dimensional variations, whereby additional latent electrostatic images may be properly aligned with respect to said latent electrostatic image to allow placement of a plurality of latent electrostatic images on said dielectric material.
