More Information
Summary:A print cartridge is described for charged particle deposition of latent images on a receptor surface adapted to move longitudinally. The cartridge has driver electrodes extending transversely with respect to the movement of the receptor surface and a dielectric covers the driver electrodes. Finger electrodes on the dielectric extend angularly with respect to the driver electrodes with the dielectric separating the finger and driver electrodes. The finger electrodes define primary and secondary apertures where the driver and finger electrodes intersect for depositing latent images of discrete dots spaced transversely on the receptor surface upon selective activation of the driver and finger electrodes. The apertures in each finger electrode are counted in the direction of motion of the receptor surface and the majority are separated transversely from one another by at least two dot spaces and the second and last apertures are spaced transversely with reference respectively to the first and last-but-one apertures in the same transverse direction.
