B. Remedy for height of bin roller

The lower dummy roller is an eccentric structure
to allow the height of the bin roller to be adj ustable.
This is provided to adjust the height where the tip
of the lead cam comes into contact with the bin
roller.
When the bin roller is replaced or reassembled,
check the specified dimension. As necessary,
change the mounting angle of the lower dummy
roller for adjustment.

1) Adjusting method
Vertically stand the bin unit, and measure the dis­tance between the upper dummy roller “A” and bin
roller “B”. If it is wider, turn the lower dummy roller
“C” counterclockwise. If it is smaller, turn it clock­wise. Assemble them at the position where the
value becomes the nearest to 97.8 mm.

2) Parallelism adjustment of guide bar

3. Parallelism adjustment of guide bar

If the bin unit is disassembled or the upper fixing
screw of the guide bar is removed, adjust the par­allelism of the guide bar.

1) Adjusting method

Set the paper sheet of B5 or A4-R at the bin 1
and bin 20, one sheet for each. Push the guide
bar “A” in the matching direction with hand to bring
it into contact with the paper sheet.
Check the contact extent of the sheet and guide
bar at the bin 1 and bin 20. If they are not in parallel
contact, loosen the screw “C” of the guide bar
holder “B”, and adjust them to be parallel.

[9] Operational descriptions

1. Outline

In the operational mode set in the copying ma­chine, the machine sorts and staples the copied
paper sheets which are discharged.
Moreover, the copied paper sheets discharged can
be stapled by operating the keys on the operation
area of the machine.
There are four operation modes as shown below.

1. No-sort mode

2. Sort mode

3. Group mode

4. Staple/sort mode

A. No-sort mode

The machine has a cascade type stacking function,
and the copied sheets are discharged. They are
charged sequentially from 1st bin according to the
paper sizes or 25 sheets by 25
sheets. When they are charged up to 20th bin, the
sorter and copying machine will stop the operation.
Remove all the copied paper sheets from the bin
and press the copy start key, and it will start copy­ing the remaining sheets.(The possibili ty of copyi ng
the paper sheets beyond the max.chargeable
sheets in the sorter, the number of the sheets
which stops the operation and the method to restart
the copying are different depending on the main
body of the copying machine.)

B. Sort/group/staple an d sort mode

The copied sheets are discharged into the sort
bins.
In this case, the bin unit moves up and down for
sorting.
If stapling is moreover necessary, the copied
sheets which are discharged into the bins will be
stapled.

3. Operation of components

A. Carrier drive system
(1) Outline

SF-S56

In the carrier system, the copied sheet sent from
the main body of the copying machine is sent out
to the bin with the carrier roller. The carrier roller
is driven by the carrier motor (M2).
Moreover, the carrying state of the paper sheet is
detected with the discharged paper sensor (PS1)
on the circuit PWB of the sorter controller.

M3

PS1

The stepping motor of the 4-phase control is used
as the carrier motor. The carrying speed is control­led according to the number of pulses of the pulse
signals A, A*, B and B* of the motor driver IC
(Q23).

(2) Carrier speed control

1) Out line

The carrying speed is controlled with the carrier
motor (M2) and torque limiter.
The carrier motor is used to merely change the
carrying speed according to the paper size and
runs at the constant speed during carrying but does
not control the speed. The carrying speed of the
machine is faster than the process speed of the
main body. If any copying paper is jammed at the
fixer of the main body and the carrier roller of the
machine, the running speed of the carr ier roller is
slowed down by the torque limiter.

2) Process speed

The process speed is applied during the period
from when it is started to receive the copying sheet
paper from the copying machine to when the paper
is completely drawn into the sorter, and is equal
to the process speed of the main body of the copy­ing machine.

2) Operation for stack over

If any chargeable number of sheets in the bin in
each mode is exceeded, the machine will proceed
with the following procedure.

a. No-sort mode

<Setting example>

RADF is used.

•

Paper of a small size is used.

•

5 original sheets

•

30 sheets are preset.

•

1) Set the conditions as shown above, and press on
the copy start key.

h

2) Every time the original sheet is changed at the 1st
bin, the copied sheets are discharged 50 sheets by
50 sheets.

h

3) When 101st sheet is discharged to the 1st bin, the
operation is stopped.

h

4) Remove the copied sheets from the 1st bin, and
press on the start key again, and the remaining
sheets (49 sheets) will be copied and discharged to
the 1st bin.

b. Sort mode

Whether the copy start is received or not is de­pendent on the specifications of the copying ma­chine.

c. Group mode

Whether the copy start is received or not is de­pendent on the specifications of the copying ma­chine.

When RADF is used

If 20 or more original sheets are charged, the op­eration will be stopped after the copied sheet is
discharged to the last bin. Remove all the paper
sheets from in the bin, and press on the copy start
key, and the remaining original sheets will be cop­ied.

When RADF is not used

If the sheet is discharged to the lowest bin, the
next copy start key will not be rec eived unless the
paper sheets in the bin are all removed.

(4) Jam

If the sorter senses the jammed paper, the jam
signal (SJAM)will be sent to the main body of the
copying machine. According to the signal, the
copying machine stops the c opyi ng operation, li ght­ing [paper feed check notice] on the operation sec­tion.
After correcting the jammed area, press on the
copy start key again, and the jam-compensated
number of sheets will be automatically copied and
be discharged to the bin.
On the other hand, if any jam occur s in the copying
machine,the operation will be stopped after the
copied sheets which are carried in the sorter are
all discharged to the specified bin.

9 – 12

Reference:

If any jam occurs in the sorter , separate the sorter
from the copying machine (turn off the joint sensor),
remove the jammed sheets and set the sorter on
the copying machine, and the trouble will be reset.

SF-S56

1) Carrying delay jam

If the paper discharge sensor does not sense any
paper even though the carrying time ( different de­pending on the main body of the copying machine)
for 300 mm has elapsed since the machine re­ceived the paper discharge signal of the main body
of the copying machine.

during operation, the SJAM signal will occur.

After the above jam occurs, correct the jam and
press the copy start key again, and the remaining
number of sheets will be automatically copied by
the jam compensation function. On the other hand,
if any jam occurs in the copyi ng machine, the sorter
will be automatically stopped after the copied sheets
which are being carried in the sorter are all dis­charged to the specified bins.

1) Composition of bin unit

The bin unit is composed as shown below.
On both ends of each bin, the rollers are installed
from the outer side of the bin frame. The dummy
rollers above and below them are unitized with the
bin unit and are fixed on both sides of the bin
frame. Moreover, the lower dummy roller on the
lower side is an eccentric structur e and is used for
height adjustment of the roller.

The lead cam is rotated to move the roller up and
down along the inclination of the lead cam in order
to move up and down the bin which is joined with
the bin frame and roller.

2) Movement of lead cam

The lead cam is installed in engagement with the
roller of the bin unit. The lead cam is driven by the
bin shift motor(M1) which can rotate forward and
reversely.

Lead cam

However, if the groove of the lead cam is inclined
throughout the range, the lead cam will be rotated
by the weight of the bin unit when the bin is
stopped. Therefore, the horizontal area is provided
on the groove of the lead cam as shown below.
When the bin unit stops, it is detected with the lead
cam home position sensor (PI2) in order to position
the roller at the horizontal area.

3) Bin shift motor control

The control circuit diagram is shown below.
The bin shift motor (M1) is a DC motor to move
up and down the bin unit through the control of the
drive circuit.
The ascending and descending speed of the bin
unit is detected by the shift motor clock sensor and
is controlled.
The stop position of the bin unit is detected with
the lead cam position sensor.

SF-S56

When the stapler unit is not at the home position,
24V power supply is shut down by the stapler
home position switch to prevent the bin shift motor
from rotating in order to avoid a collision between
the bin unit and the stapler unit.
The upper-limit and lower-limit sensors of the bin
unit prevent the overrun.
Moreover, the current detection circuit is provided.
When the bin unit comes into contact wi th the bin
unit, the overcurrent is detected to stop the bin unit.

The in-bin paper sensor is composed of LED and
photo transistor to detect whether paper is present
in the bin or not.
In order to prevent a malfunction which results fr om
the light intensity variation and so on of the sensor,
the paper detecting level is automatically compen­sated at a certain interval.

Caution:

If the receiver (S2) of the sensor receiv es any ex­ternal light or other strong light during compensa­tion of the paper detecting level, a wrong
compensation value will be memorized. In this
case, the error code “E525” will be displayed on
the operation area of the copying machine.

(5) Other sensors

1) Bin unit low er-limit detection sensor (home po­sition sensor)

The bin unit will return to the home position when
the copy start key is pressed on or when the sheets
discharged into the bin are all removed.
In this case, the actuator area which is unitized
with the bin unit goes out of the lower-limit sensor
(PI4) of the bin unit and the sensor is turned on
to send the signal to CPU on the sorter controll er
PWB.
If the bin unit lowers farther from the home position,
the lead cam home position sensor will be turned
off to detect the lower limit. The sorter control PWB
will immediately stop driving the bin shift motor
(M1). Moreover, the error code will be displayed
on the operation area of the copying machine.

2) Bin unit upper-limit detection sensor

The upper limit of the bin unit of the machine is
detected with the actuator area which is unitized
with the pin unit, and the bin unit upper-limit de­tection sensor (PI5).
If any trouble occurs and the bin unit tries to rise
beyond the 20th bin, the actuator area will go out
of the upper-limit detection sensor to turn on the
sensor. The signal will be sent to CPU of the sorter
controller circuit PWB to immediately stop driving
the bin shift motor (M1). Moreover, the error code
will be displayed on the operation area of the copy­ing machine.

D. Comm unication between copying machine and

sorter

1. Outline

The main body of the copying machine, and the
sorter communicate the status signals with each
other through IPC (IC for communication) commu­nication.
The machine is provided with the communication
function of new IPC and old IPC which are switch­able according to the main body of the copying
machine. For switching, turn on or off the DIP
switch 6 of the SW1 unit on the sorter controller
PWB.

system

Old IPC type New IPC type

These signals are written on RAM on the sorter
controller PWB, and they are output according to
the control signals from CPU (Q1).
Moreover, though the service man can not check
whether the status signal is properly carried or not,
the self-diagnosis function of the copying machine
will be activated to display the error code on the
operation section of the copying machine if any er­ror occurs during transfer of the signal. (Code: F1-
