4)

The operations described in steps (1) to (3) are repeated for each sheet to stack the sheets on the processing tray.

5)

The stacked sheets are stapled or staple-free stapled (only when in the relevant mode).

6)

After being shifted, the paper stack on the processing tray that has been stacked by the assist guide are delivered to the delivery tray.

7)

After the paper stack has been delivered, the paper retainer holds down the stack in the delivery tray.

The finisher performs the following initialization operation depending on the status.

*1:Target sensors

The feed unit feeds the paper delivered from the host machine to the processing tray unit. 
A Delivery sensor (FNPS1) is provided along the paper feed path in the feed unit to detect the paper feed state and jam.

At power ON

If the target sensors*1 are aware of the home positions, initialization is not performed.
Only before starting a job, the Stack tray paper height sensor (FNPS9)
detects the paper height.

When recovering from sleep mode

At the start of a job

At the end of a job

After the cover is closed

Initialization is performed regardless of the sensor status. If at the home position, initialization is performed by moving the 
sensor away from the home position.

MX-FN27, MX-PN14  OPERATIONAL DESCRIPTION  6 – 5

The paper delivered from the host machine is fed by the inlet roller and delivery roller.
The paper delivered by the delivery roller is stacked on the processing tray by the paddle.
The inlet roller, delivery roller, and paddle are driven by the Feed motor (FNM1).
When the rear paper flap lever driving solenoid is driven, the rear paper flap lever moves up. 
When the Paddle motor (FNM10) runs, the paddle unit moves down. The paddle makes contact with the paper and feeds the paper to the processing
tray unit.

The processing tray unit aligns, shifts, and staples or staples without staples the deliveredpaper. Then the assist guide and assist claw deliver the
paper onto the delivery tray.

The names and functions of the components of the processing tray are as follows:

Paddle

Feeds the paper delivered from the delivery roller to the processing tray unit.

Return Belt

Feeds the paper to the rear of the processing tray unit and presses the paper against the stopper.

Stopper

Allows the paper stacked on the processing tray to be pressed against itself to align the paper in the feed direction.

Front/Rear Alignment Plate

Aligns the paper stacked on the processing tray in the width direction and shifts the paper.

Assist Guide

The assist guide supports the trailing edge of the paper stacked on the processing tray unit, and the assist claw delivers the 
paper stack by pushing the stack onto the delivery tray

Assist Claw

Stapler Unit

Staples the sheets.

Staple-free Staple Unit

Staples sheets without using staples.

Paper Retainer

Holds down the paper stack in the delivery tray.

The paper delivered from the delivery roller is stacked on the processing tray and aligned in the feed direction.

How paper is delivered from the delivery roller and stacked on the processing tray is described below.

1)

After the Delivery sensor (FNPS1) detects the trailing edge of the paper, the Paddle motor (FNM10) runs to move the paddle unit down. The pad-
dle driven by the Feed motor (FNM1) delivers the paper toward the processing tray. After a given time elapses, the paddle unit is moved up.

2)

After the Delivery sensor (FNPS1) detects the trailing edge of the paper, the Return belt motor (FNM2) runs to move the return belt unit down.
The delivered paper is pressed against the stopper by the return belt driven by the Feed motor (FNM1) and aligned in the feed direction. After a
given time elapses, the return belt unit is moved up.

NOTE: Paper is not fed by the returned belt if the paper width is more than 297.0 mm or less than 120 mm or if the paper is special paper or enve-

lopes.
