*1 Main Tray Up/Down
The tray up/down motor (M703) and the worm
gear installed on the motor shaft perform the
winding operation of the up/down wire. The rota-
tion direction of the motor shaft determines the
moving direction of the main tray, i.e. rise or fall.
If the up/down pulley/L rotates clockwise seen
from the front, the main tray rises. Otherwise, the
main tray falls.
In old type, a brush motor is used for M703 but in
2
new type brushless motor and timing belt are
used to enhance the silence effectiveness.
*2 Paper Detection
The distance between the top surface of the piled
sheets on the main tray (the top surface of the
main tray if there's no sheet on the tray) and the
paper exit opening is monitored using the tray
upper limit PS (PS702) and the stapler paper exit

upper limit PS (PS707). This distance is kept con-
stant to avoid misalignment of delivered sheets.
The counting program, built in the FNS, counts
the number of delivered sheets on the main tray
during continuous copying. When the total num-
ber of delivered sheets reaches a maximum (val-
ues are predefined depending on type/size of
paper), the copying operation is suspended.
However, when some delivered sheets are
removed, the main tray is raised and the counter
reset PS is activated. This resets the current
sheet counter. This enables limitless delivery.
The tray lower limit PS (PS703) detects the bot-
tom of the main tray. The number of delivered
sheets on the main tray is not counted by the
software counter during non-continuous copy-
ing. PS703 is used for the limitation of the num-
ber.
