Abstract

A delivery unit and method for removing carrier vapor in a wet-type printer. The delivery unit includes a delivery guide, delivery rollers and a duct for collecting carrier vapor generated from a paper by the latent heat on the paper passing through the delivery guide in order to prevent the carrier vapor from leaking outside of the printer. The carrier vapor collection duct includes upper and lower housings connected to each other to form a predetermined space therein. The upper housing has a vent on one side thereof and an air inlet on the opposite side. A fan is mounted on the vent. The carrier vapor is collected in the duct of the delivery unit and then sent to the catalyst unit by the fan to be oxidized. Accordingly, the delivery unit can prevent the white carrier vapor generated from the paper passing through the delivery unit from leaking outside the printer.
