Paper Cooling

There two sets of exhaust fans and two sets of cooling fans in the buffer pass unit. These fans turn on in 0.1

seconds interval as follows below after the mainframe has turned on or received a printer job or copy job.

• Upper exhaust fans [A] > lower exhaust fans [B] > upper cooling fans [C] > lower cooling fans [D]

The lower cooling fans [D] draw air in the buffer pass unit from the outside, and then move air [E] to the

upper area along with the outer of the paper path. This makes the outer of the paper path cooler. Finally

air around the upper area is expelled to the outside by the upper exhaust fans [A].

Also the upper cooling fans [C] draw air in the buffer pass unit from the outside, and then move air [F] to

the center area along with the inner of the paper path. This makes the inner of the paper path cooler. Finally

air around the center area is expelled to the outside by the lower exhaust fans [B].

Two sides of the paper path guide remove heat from a sheet of paper while a sheet of paper is being

transported. As a result, a sheet of paper from the exit of this unit is properly cooled.

The fan operation time after the initializing or job end can be adjusted by SP1940-008 (adjustable from

0 to 60 minutes/ default: 10 minutes).
