Drum Ventilation
A Peltier unit [A] on the right side of the copier dries air before it is sent through a
common duct [B] to the PCUs. This prevents condensation around the drums.
The polarity of this Peltier is set so the left side [C] is the cold side and the right [D]
is the hot side.
The Peltier cooling fan [E] pulls air into the machine. The air passes through the
cold side where the moisture condenses and drains into a small reservoir [F]. The
four PCU fan motors
,
,
,
(Y, M, C, K). pull the dried air from the common
duct into the PCUs to keep dry the air around the drums.
The moisture is absorbed by an absorbent pad (not shown) below the Peltier unit.
The hot laminated plates on the right side of the Peltier unit evaporate the moisture.
The Peltier circulation fan [G] sends the hot air out of the machine.
