MX-7000N  TRAY PAPER FEED SECTION  F – 5

The paper feed tray 1 is used exclusively for A4, 11 x 8.5, or B5
paper size.
The paper feed tray 2 is used for A4 (11 x 8.5) paper size.

1)

When copy/print operation is started, the motors (CPFM) and
the clutch (T1PFC) are turned on to turn on the solenoid
(T1PUS) at the timing of paper pickup. This rotates and falls
the take-up roller to pick up paper.

2)

At the same time, the paper feed roller rotates to feed paper to
the transport section. At that time, the separation roller rotates
to prevent against double feed of paper.

• When the paper is set and the paper feed tray is inserted, the

pickup roller moves down and the paper feed tray sensor turns
ON.

• The lift-up motor operates to lift the rotating plate.
• The paper upper limit sensor turns on to stop the rotating plate at

the specified position.

• When copy/print operation is started, the motor and the clutch

are turned ON and the pickup roller is rotated in the paper pickup
timing to feed paper.

• At the same time, the paper feed roller rotates to feed paper to

the transport section. At that time, the separation roller rotates to
prevent against double feed of paper.

• Remaining paper detection is performed according to four

stages, i.e. three stages with paper and one stage with no paper,
and the result is displayed.

• The number of remaining sheets is determined according to the

number of times the remaining paper sensor changes from the
time the paper feed tray starts lifting up to the time when the
upper detection sensor comes ON.
