Abstract
Cleaning apparatus for an imaging cylinder in an ion deposition printer includes a housing having an upper portion and a lower portion, separated by an internal plate. The lower portion includes a plenum chamber having an opening at one end and a vacuum port at an opposite end, and a scraper blade mounted in the plenum chamber and having an edge engaging the imaging cylinder. A continuous cleaning web is mounted in the upper portion engaging the imaging cylinder downstream of the scraper blade. The cleaning web is impregnated with silicone oil. A related method includes the steps of a) engaging the peripheral surface of the imaging cylinder with a scraper blade to remove toner particles therefrom; and b) engaging the peripheral surface of the imaging cylinder downstream of the scraper blade with a continuous web impregnated with oil to remove residual toner particles and conductive powder deposits.
