Stapler junction gate: Directs paper either to the lower exit or to the stapler tray.
Pre-stack tray: When staplin g multiple prints (A4 LEF, LT LEF, B5 LEF only) in the

staple mode, the first sheet of the second print waits here for the next sheet to feed
while the previous stack is stapled. After the second print is fed, the first and
second sheets are fed together to the pre-stack tray. This delay allows enough time
for the previous stack to be stapled without interrupting paper feed.

Tray 1 (Upper Tray)

In sort/stack mode, tray 1 [A] moves from side to side to separate the printed sets.

The tray 1 shift motor [B], inside the shift tray, controls the horizontal position of

tray 1 through the timing belt [C] and gear disk [D].

After one print set is delivered to tray 1, the shift motor turns on, driving the gear

disk and the arm [E], and the tray drive unit moves to one side.

Two shift sensors [F] detect when to stop this side-to-side movement. There is a

cut-out in the gear disk. The shift tray moves in one direction until one of the shift

sensors detects the cut-out. Then the shift tray stops.

The next set of prints is then delivered, and the gear disk is turned in the opposite

direction until the other shift sensor is activated.

The shift mechanism for tray 2 is similar to that used for tray 1. However, when the

tray 2 shift motor [B] turns on, the arm [D] moves the entire end fence [C] from side

to side (not just the tray).

After the gear disk has turned 180 degrees, the cut-out in the gear disk enters the

tray half- turn sensor [E], and the motor stops . When the next set of prints is

delivered, the motor turns on again, and moves the tray back to its previous

position.

Introduction

The tray 1 lift motor [A] controls the vertical position of tray 1 [B] through gears and

timing belts [C].

Normal and sort/stack modes

When the ma in s witch is turned on, the tr ay is initialized at the upper position. To

do this, the tray is moved up until upper stack height sensor 1 [D] is de-actuated.

During printing, if upper stack height sensor 2 [E] is actuated, the tray 1 lift motor

lowers the tray for a specified time.

When the tray lowers during printing, th e actuator [F] will pass through the tray 1

overflow 1 sensor [G]. When the actuator drops below the sensor (to deactivate the

sensor), the machine detects that the paper stack height has exceeded the

overflow limit.

The upper limit switch for tray 1 [H] prevents the drive gear from being damaged if

the upper stack height sensor 1 should fail. If the tray is raised to the tray

positioning roller [I], the switch will automatically cut the power to the tray 1 lift

motor.

G565D204.WMF

In staple mode, stapled stacks can be delivered to either tray, but they can only go

to the lower exit. So, if tray 1 is selected, tray 1 [A] moves down to the lower paper

exit.

Tray 1 lowers until the actuator [B] enters the tray 1 lower limit sensor [C]. Tray 1

then lifts up until lower stack height sensor 1 [D] is activated.

When tray 1 is moved down to the lower exit, tray 2 must be moved down out of

the way. So, tray 2 [E] is also lowered until the tray 2 shunt position sensor [F]

detects tray 2 (or the top of the paper stack in tray 2).

The method of paper height detection is the same as for the upper exit area.

When the tray lowers during printing, t he actuator will enter the tray 1 overflow 2

sensor [G]. When this happens, the machine detects that the paper stack height

has exceeded the overflow limit.

G565-21

TRAY UP/DOWN MECHANISMS 23 February, 2001

Tray 1 release mechanism

When tray 1 is selected for staple mode, tray

1 must be moved down to the lower paper

exit. However, to move past the sensors at

the lower exit, the tray must be moved away

from the finisher.

To do this, the tray 1 shift motor turns until

the cut-out in the gear disk enters the tray

release sensor [A]. At this time, the arm [B]

has reached position [C], and is pushing

against the plate [D], in towards the finisher.

However, the plate is fixed, so the tray

moves out away from the finisher.

Then, the tray 1 shift motor stops, then the

tray 1 lift motor lowers tray 1.

When the tray 1 lower limit sensor is

activated (as described on the previous

page), the tray has moved past the sensors

at the lower exit. The tray 1 shift motor turns

on again until the gear disk activates the

tray shift sensor [E]. This moves the tray

back against the finisher.

[D]

[B]

[C]

[A]

G565D201.WMF

[E]

Next, tray 1 lifts until the finisher detects that

the tray is at the correct height.

When tray 1 is at the lower exit, the tray lock

solenoid [F] is on, and the lever [G] locks

the tray. This prevents the user from mov ing

the tray out of position (the first tray has

some play when it is at the lower position).

Before tray 1 goes back to the upper exit

area, the tray lock solenoid [F] turns off to

unlock the tray. In addition, the back fence

lock clutch [H] turns on to hold the back

fence [I]. This prevents the springs inside

the back fence from suddenly contracting

(these springs normally keep the tray steady

during side-to-side shift).

Then, tray 1 is released and it moves up to

the upper exit area.

The tray 2 lift motor [A] controls the vertical position of tray 2 [B] through gears and

The paper height detection is the same as for tray 1.

When the tray lowers during printing, the tray is judged to be overflowing when the

tray 2 overflow sensor 1 [D] is off and the tray 2 overflow sensor-2 [F] is on (see

‘Normal Mode’ in the above diagram).

In the multi-tray staple mode (selected by the service technician), the machine

detects that the paper stack height has exceeded the overflow limit when the

actuator [E] enters the tray 2 overflow 1 sensor [D].

The lower limit sensor [G] for tray 2 detects when tray 2 is at its lowest limit and

stops the tray 2 lift motor.

The function of the tray 2 upper limit switch [H] is the same as for tray 1.

NOTE: This feature is available only when using A4 L, LT L, and B5 L.

During stapling, the main machine must wait. This mechanism reduces the wait by

holding the first two sheets of a job while the previous job is still being stapled. It

only works during the second and subsequent sets of a multi-set print job.

The pre-stack junction gate solenoid [A] switches on after the first sheet activates

the entrance sensor. This directs the sheet to the pre-stack tray [B].

The pre-stack feed roller [C] stops for a specifie d time after the trailing edge of the

paper has passed through the entrance sensor and stops the paper from leaving

the pre-stack tray.

At the same time, the pre-stack junction gate solenoid switches off, and the second

sheet is sent to the paper guide [D]. The pre-stack feed roller (controlled by the

pre-stack motor) starts to rotate again for a specified time after the trailing edge of

the second page has been passed through the entrance sensor, and then both

sheets are sent to the stapler tray together.

In staple mode, each sheet of print paper is vertically and horizontally aligned when

it arrives in the stapler tray.

Vertical Paper Alignment

After the trailing edge of the paper passes the stapler tray entrance sensor [A], the

positioning roller solenoid [B] is energized for a specified time to push the

positioning roller [C] into contact with the paper.

The positioning roller rotates to push the paper back and align the trailing edge of

the paper against the stack stopper [D].

Horizontal Paper Alignment

When the start key is pressed , the jogger motor [E] turns on and the jogger fences

[F] move to the waiting position, which is 8 mm wider on both sides than the

selected paper.

When the trailing edge of the paper passes the stapler tra y e ntrance sensor, the

jogger motor turns on to move the jogger fences 5 mm towards the paper. After a

short time, the jogger motor turns on again for the horizontal paper alignment then

returns to the waiting position.

The stapler can be moved from side to side or rotated according to the

requirements of the selected stapling mode.

Stapler Rotation

After the start key is pressed, the stapler rotation motor [A] rotates the staple unit

[B] until the stapler rotation HP sensor [C] is activated. Then, the stapler moves

from front to rear of the finisher.

When oblique stapling at one pos ition has been selected, after the stapler moves

to the stapling position, the stapler rotation motor rotates the stapler 45 degrees

(clockwise) at the stapling positio n before the stapler fires.

Side-to-Side Movement

The stapler motor [D] moves the stapler from side to side. After the start key is

pressed, the stapler moves from its home position to the stapling position.

The amount of movement required to reach the stapling position is determined by

the size of the selected paper. If the two-staple mode is selected, the stapler

moves to the front stapling position first, and then moves to the rear stapling

position. However, for the next print set, it staples in the reverse order.

After the stapling job is finished, the stapler returns to its home position,

determined by the stapler HP sensor [E].

The staple hammer is driven by the stapler hammer motor [A] inside the stapler.

As soon as the paper stack is aligned, the staple hammer motor starts. When

stapling is finished, the staple hammer HP sensor [B] is turned on, and the staple

hammer motor then stops.

The staple end sensor [C] detects the staple end condition and whether the staple

cartridge is installed or not. If a stapler cassette is not installed, or after the stapler

cassette runs out of staples, a message is displayed in the operation panel. If this

condition is detected during a print job, the indicator will appear, but the print job

will not stop.

The staple position sensor [D] detects if there is a staple sheet at the stapling

position. After a new staple cartridge is installed, the staple hammer motor turns on

to transfer the staple sheet until the staple position sensor is activated by the staple

sheet.

If a staple jam occurs and overloads the motor, this causes a staple jam message

to appear on the operation panel.

G565D115.WMF

[D]

[G]

[F]

[H]

G565D114.WMF

When stapling starts, the exit guid e plate motor [A] switches on and opens the exit

guide plate [B], so that the stapled stack can exit to the tray. The exit guide plate

sensor [C] detects when to switch off the exit guide plate motor.

After the prints have been stapled, the stack feed-out motor [D] starts. The pawl [E]

on the stack feed out belt [F] lifts the stapled set and feeds it to the tray [G].

The exit guide plate closes at a specified interval after the stapled prints have

started to feed out. Then the exit roller takes over the stack feed-out. The stack

feed-out motor turns off when the pawl actuates the stack feed-out belt home

position sensor [H].

[E]

When tray 1 is passing this area on its way back up to the upper exit, the exit guide

safety switch [I] cuts power to the tray lift motor if the guide is opened too far. This

prevents damage to the user’s fingers if they are inside the lower exit when the tray

is moving up.

23 February, 2001 PUNCH UNIT (OPTIONAL)

4.8 PUNCH UNIT (OPTIONAL)

The punch unit punches holes in printed sheets, one by one. The punch unit is

provided with a new punch mechanism to improve the accuracy of punching.

4.8.1 PUNCH DRIVE MECHANISM

The punch drive mechanism is driven by the punch motor [A]. Each sheet is

positioned and punched by pressure f rom above. A certain time after the trailing

edge of the paper passes through the finisher entrance sensor [B], the punch

motor turns on and the paper stops. Then the punch clutch [C] turns on to make

the punch holes.

[H]

[G]

Peripherals

The home position is detected by the punch HP sensor [D]. When the cut-out in the

punch shaft disk [E] enters the punch HP sensor, the punch clutch turns off.

When the finisher has received the command that changes the number of punch

holes, the punch hole motor [F] turns on until the disk changes the status of the

punch hole switch [G] (until it switches on or off). This indicates that the cover [H]

and the punch cam [I] have moved to one side or the other to change the number

of holes.

G565-29

PUNCH UNIT (OPTIONAL) 23 February, 2001

4.8.2 PUNCH WASTE COLLECTION

[A]

[B]

[C]

G565D153.WMF

Waste punchouts are collected in the punch waste hopper [A] below the punch unit

inside the finisher.

When the top of the punchout waste in the hopper reaches and actuates the

hopper sensor [B], a message will be displayed on the operation panel after the

current job is completed.

This sensor also detects whether the punch waste hopper is installed. When the

waste hopper is taken out, the arm [C] moves down and this will actuate the sensor

and display a message in the operation panel. This message is the same as for the

hopper full condition.
