Elektrostatografischer Drucker zum Erzeugen eines Bildes auf einem Empfangselement

摘要

An electrostatographic printer is described for forming an image onto a moving web (6) or sheet. The printer comprises a number of toner image-producing electrostatographic stations (A, B, C, D, E) having rotatable endless surface means in the form of a drum (21) onto which a toner image can be formed. A development station (4) forms a toner image on the drum (21). Drive rollers (22) convey the web (6) past the image-producing stations. Corona discharge devices (5) transfer the toner image on the drum surface onto the moving web (6). The printer includes an air-conditioning device comprising filters (30, 33) for removing dust and ozone from air leaving the environment of the image-producing station, a heat exchanger (34) and a humidifier (35) for adjusting the temperature and humidity of air leaving the environment of the image-producing station, thereby to produce conditioned clean air, and an inlet manifold (36) for introducing a stream of the conditioned clean air into the environment of the image-producing stations. <IMAGE>
