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.
B070/B071
Name
Drives the transport rollers in the bypass tray.
Drives the paper feed roller in the bypass tray.
Drives the grip clutch in the bypass tray.
Drives all rollers in the bypass tray.
Lifts and lowers the tray.
Detects the copy paper coming to the paper feed
roller and checks for misfeeds.
Detects when the paper in the bypass tray is at
the correct paper feed height.
Detects when the tray is at its lowest possible
position.
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
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.
Detects the paper height in the bypass tray.
Detects the paper height in the bypass tray.
Controls up-down movement of the pick-up roller
in the bypass tray.
Switches the tray lift motor on and off to lift and
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
width, four feelers inside the paper size switch
slide along wiring patterns of a terminal plate. The
wire pattern detected determines the paper width.
