9.3.1 ELECTRICAL COMPONENT DESCRIPTIONS

Symbol	Name	Function
Clutches
MC8	Transport	Drives the transport rollers in the bypass tray.
MC9	Paper Feed	Drives the paper feed roller in the bypass tray.
MC10	Grip	Drives the grip clutch in the bypass tray.
Motors
M5	Tray	Drives all rollers in the bypass tray.
M6	Tray Lift	Lifts and lowers the tray.
Sensors
S23	Paper Feed	Detects the copy paper coming to the paper feed
		roller and checks for misfeeds.
S24	Lift	Detects when the paper in the bypass tray is at
		the correct paper feed height.
S25	Lower Limit	Detects when the tray is at its lowest possible
		position.
S26	Paper End	Informs the copier when the paper in the bypass
		tray has run out.
		Used with the paper width switch to determine
		paper size. This sensor is activated when paper is
		set for short edge feed. For example, when the
S27	Paper Length	paper width switch detects A4 width and this
		sensor is off, the machine determines A4 is set for
		long edge feed. When A4 width is detected and
		the paper length sensor is on, then the machine
		determines that A3 is loaded for short edge feed.
S28	Paper Height 1	Detects the paper height in the bypass tray.
S29	Paper Height 2	Detects the paper height in the bypass tray.
Solenoid
s
SOL7	Pick-up	Controls up-down movement of the pick-up roller
		in the bypass tray.
Switches
		Switches the tray lift motor on and off to lift and
SW5	Tray Lift	lower the bottom plate of the tray. This switch
		must be pressed to start paper feed.
		A slide switch connected to the side fences. When
		the side fences are moved to match the paper
SW6	Paper Width	width, four feelers inside the paper size switch
		slide along wiring patterns of a terminal plate. The
		wire pattern detected determines the paper width.

The numbering for the components does not start at 1 because the point-to-point diagram for the bypass tray is included on the diagram for the LCT. For the purpose of component numbering, they are considered together as one unit.
