Delivery unit and method with a carrier vapor collection duct and a carrier purifier using the same

A carrier purifier for a wet-type printer, which comprises:

• a delivery unit for guiding a paper which is exiting along a paper path from the printer, the delivery unit comprising a delivery guide and a duct for collecting carrier vapor generated from the paper by the latent heat remaining on the paper during the paper exit, the delivery guide comprising a first guide member and a second guide member spaced a predetermined interval from each other to form the paper path, the duct comprising an upper housing and a lower housing, the delivery guide being disposed in the duct to form a first air passageway located between the first guide member and the upper housing and a second air passageway located between the second guide member and the lower housing, the first and second air passageways being substantially coplanar with the paper path;
• and
• a vent arranged on one side of the duct and an air inlet arranged on the side opposite to the vent to direct airflow through the first and second air passageways to facilitate the discharge of the carrier vapor through the vent.
• a fan for discharging the carrier vapor collected in the carrier vapor collection duct;
• and
• a catalyst unit for oxidizing the carrier vapor discharged by the fan.

A method for removing carrier vapor in a wet-type printer, the method comprising:

• guiding a paper fused with an image to exit the printer via a delivery guide along a paper path;
• and
• collecting carrier vapor generated from the paper by the latent heat remaining on the paper via a duct, the duct forming first and second air passageways disposed on opposite sides of the delivery guide;
• positioning a vent on one side of the duct to discharge the carrier vapor collected in the space;
• and
• positioning an air inlet on the side opposite to the vent to direct airflow through the first and second air passageways in a direction substantially coplanar with the paper path to facilitate the discharge of the carrier vapor through the vent.

A method for removing carrier vapor in a wet-type printer, the method comprising:

• guiding paper exiting along a paper path from the printer via a delivery unit having a delivery guide for forming the paper path and a duct for collecting carrier vapor generated from the paper by the latent heat remaining on the paper during the paper exit, the duct forming first and second air passageways disposed on opposite sides of the delivery guide;
• discharging the carrier vapor collected in the carrier vapor collection duct in a predetermined direction via a fan;
• oxidizing the carrier vapor discharged by the fan via a catalyst unit;
• and
• providing a vent and an air inlet via which air flows through the first and second air passageways in direction substantially coplanar with the paper path to facilitate the discharge of the carrier vapor through the vent.
