PAPER END DETECTION

2.4.2 LINK LEVER

[C] [D]
[B]

Function

[A]
A link lever is located on the top
cover. The link lever lifts the
feeler of the paper end sensor up
towards the paper tray unit's top
[E]
cover when the paper tray is
removed from the paper tray unit.
The link lever also allows the
feeler to drop down when the
paper tray is in the paper tray
unit. Because of this mechanism,
the feeler is not damaged when
you insert or remove the paper
tray.

Mechanism

When the paper tray [F] is out of
[F]
the paper tray unit, the spring [A]
pulls one end of the link lever [B].

The other end of the link lever pushes the paper end sensor feeler [C] upwards.
When the paper tray is inserted into the paper tray unit, the paper tray pushes one
end of the link lever [D]. The other end of the link lever moves away from the feeler.
The feeler [E] then lowers on to the topmost sheet of paper in the paper tray.
