There is a fan (with filter) at each end of the LPH unit.
The fans pull air into the machine and circulate it around the LPH
unit.
Both fans switch on when the main motor and fusing/exit motor
switch on, and they switch off when these motors switch off.
SP2940 controls the operation of these two fans.
