Engine/LVPS Board	CN5 and leave the cables connected
Power Switch	to the power switch attached. With
	the printer positioned on its left side
	and the engine/LVPS board
	positioned on a flat surface, turn the
	power switch on and check the AC
	line voltage at connector CN201. If
	no voltage is present, replace the
	power switch. If line voltage is
	present, measure the voltages at
	connectors CN2 and CN5. Go to
	the“Engine/LVPS Board (model
	E310)” on page 5-4 and check for
	correct voltage measurements.

Model E312	Place the printer on its rear side.
Power Switch	Position the LVPS board on a flat
	surface with all the cables
	connected. Turn the printer power
	switch to the on position. Check the
	AC line voltage at power switch
	connector CN501. If no voltage is
	present, replace the power switch
