Paper Cooling after Fusing
 The cooling pipe [2] cools the paper immediately after it
exits the fusing unit.
 Paper cooling fans [1] in the duct dissipate the heat around
the fins [4].
Slide 468
 The paper (1) passes under the cooling pipe (2).
 The pipe has a system of capillary tubes filled with water running along the inside
of the pipe.
 The paper leaving the fusing unit heats the parts of the cooling pipe that it
touches. This heats the water inside the tubes.
 The principle of heat transference moves the heated water to toward the cooler
rear end of the cooling pipe where a heat sink with fins (4) is attached.
 The fins of the baffle conduct heat away from the water in the pipe. Air moving
around the fins dissipates the heat into the air.
