Abstract
An air circulation system for a liquid-type electrophotographic printer. The air circulation system circulates air in the printer and discharges the air to the outside. The printer includes a developer unit for developing a predetermined image onto a photoreceptor belt, a drying unit for drying the developed image, and a transfer unit for printing the dried image on a paper. The air circulation system includes: a belt cartridge having access openings and which is detachably installed in the printer to enclose the photoreceptor belt, except for portions of the photoreceptor belt to which the developer unit, the drying unit and the transfer unit have access through the access openings; sealing members for sealing the belt cartridge at the access openings to the photoreceptor belt for accessing by the developer unit, the drying unit and the transfer unit; a pump for sucking out air in the space enclosed by the belt cartridge and discharging the air to the outside; and a filter for filtering out harmful fumes from the air sucked by the pump prior to being discharged to the outside.
