What Is the DU3-64/DU3-54?

This is an auxiliary drying unit that combines a drying-heater unit and a blower-fan unit. It uses the drying-heater unit to dry the ink by warming the media after printing. It also uses the blower-fan unit to dry the ink by blowing air against the surface of the media.

An electrical outlet separate from that for the printer is required in order to use the drying-heater unit.
