Air conditioning device for a printer
First Claim
1. An electrostatographic printer for forming an image onto a moving receptor element, which printer comprises:
- (i) a plurality of toner image-producing electrostatographic stations;
(ii) means for conveying the moving receptor element past said image-producing stations, each of said image producing stations having rotatable endless surface means onto which a toner image can be formed, a development station for forming a toner image on said rotatable endless surface means and means for transferring said toner image on said rotatable endless surface means onto said moving receptor element; and
(iii) an air-conditioning device comprising means for adjusting the temperature and humidity of air to produce conditioned air, and means for introducing a stream of said conditioned air into the environment of said image-producing stations, wherein air leaving the environment of said image-producing stations is recycled to, and reconditioned by, said air-conditioning device.

Abstract
An electrostatographic printer is described for forming an image onto a moving web or sheet. The printer includes a number of toner image-producing electrostatographic stations having rotatable drums onto which a toner image can be formed. A development station forms a toner image on the drums. Drive rollers convey the web past the image-producing stations. Corona discharge devices transfer the toner image on the drum surface onto the moving web. The printer also has an air-conditioning device which has filters for removing dust and ozone from air leaving the environment of the image-producing station, a heat exchanger and a humidifier for adjusting the temperature and humidity of air leaving the environment of the image-producing station, and an inlet manifold for introducing a stream of the conditioned clean air into the environment of the image-producing stations.

19. A method for forming an image onto a moving receptor element in an electrostatographic printer which includes a plurality of toner image-producing electrostatographic stations, each of said image-producing stations having rotatable endless surface means onto which a toner image can be formed, the method comprising:
-
forming a toner image on each of said rotatable endless surface means; conveying said moving receptor element past said image-producing stations; transferring said toner image on each of said rotatable endless surface means onto said moving receptor element; adjusting the temperature and humidity of air to produce conditioned air, introducing a stream of said conditioned air into the environment of said image-producing stations, recycling air leaving the environment of said image-producing stations, and re-conditioning the air recycled from the environment of said image-producing stations. - View Dependent Claims (20)
