HP LaserJet Enterprise M607n - Fans; Solenoids; Clutches; Switches

Fans
The printer has four fans for preventing the temperature from rising in the printer and for cooling the printed
pages.
The DC controller determines whether there is a fan failure and noties the formatter if a fan locks for a
specied time from when the fan starts.
