ABSTRACT:
A liquid electrophotographic printer includes a printer body. An engine unit is installed in the printer body and includes a photoreceptor belt, a laser scanner for forming a latent electrostatic image on the photoreceptor belt, a development device for developing the latent electrostatic image by supplying a developer liquid which is a mixture of a liquid carrier and a toner, a transfer roller for transferring the developed image to a print paper, a fixation roller for pressing the print paper against the transfer roller, and a drying unit for evaporating the liquid carrier remaining on the photoreceptor belt. A closed cell encompasses the engine unit. An exhaust fan exhausts the air inside the closed cell. A filter removes the gaseous carrier from the exhausted air.
