Paper Feed
When the paper feed sensor [E] detects the trailing edge of the paper, the pick-up solenoid
[F] turns on and off. This lifts the pick-up roller [G] from the top of the stack paper briefly and
then releases the pick-up roller. This makes paper pick-up more effective.
The paper feed sensor [E] also controls the paper feed clutch "ON" and "OFF" timing.
6.11.4 PAPER LIFT
The rear end of the paper tray pushes the tray set switch (for tray 2, this is the paper size
switch). As a result, the machine detects that the paper tray is installed.
When the machine detects that a tray has been placed in the machine, the tray lift motor [A]
rotates and the coupling gear [B] on the tray lift motor engages the pin [C] on the lift arm
shaft [D]. Then the tray lift arm lifts the tray bottom plate [E]. When the tray is removed from
the machine, the connection between the coupling gear and lift arm shaft is disengaged, and
the tray bottom plate lowers. After that, the coupling gear is moved to its home position.
