5. OVERALL MACHINE CONTROL

1 August 1988

The copier main board provides the sorter main board with +24 volts and

+5 volts. +24 volts powers the roller drive motor and the indicator LEDs on
the operation panel board, and +5 volts powers all sensors and switches.
Also, +24 volts is changed to +12 volts by the regulator IC, which powers
the bin drive motor.

The copier main board controls the drive and checks the status of the sorter
via the sorter main board. The copier main board sends the scan signal to
the data select IC on the sorter main board. After receiving the scan signals,
the data select IC outputs the status of the sensor, switches, or keys as the

scan output signal.
The copier main board also sends the sorter drive signal. After receiving the

drive signals, the drive IC turns on the appropriate motors and operation
panel indicators.

6. BASIC OPERATION

- Clear Mode -

When the main switch of the copier is turned on, the sorter automatically as-

sumes the clear mode. In this mode, all copies are stacked on the first bin.
The sorter also assumes the clear mode when either the interrupt mode or
the manual feed mode is selected.

Sorter operation begins when a copy actuates the copier exit sensor. At this
time, the roller drive motor energizes. When the paper exits onto the sorter

bin, the paper sensor is de-activated and the roller drive motor is then de-

energized.

sorter main board to check for paper misfeeds.

- Sort Mode -

Pressing the Sorter key once shifts the copier to the sort mode. In this mode,

all copies of the first original are delivered to separate bins starting from the

top. The copies of the second original are delivered to the same bins, but

starting from the bottom. The copies of the third original start from the top

and so on. The bin drive motor turns on to advance the bin one step, 250

milliseconds after the copy has gone through the paper sensor. If the Copy

Quantity, Clear/Stop, Book Copy, or Sorter key is pressed during the sort

mode, all bins shift to the home position.

The copier main board monitors the paper sensor through the

- Stack Mode ­Pressing the Sorter key twice shifts the copier to the stack mode. In this

mode, all copies of the first original are delivered to the first bin, all copies of

the second original are delivered to the second bin, and so on. The bin drive

motor turns on to advance the bin one step, 250 milliseconds after the last
copy of the original has gone through the paper sensor. If the Sorter key is
pressed during stack mode, all bins shift to home position.

The exit rollers [A] take over paper transport from the copier. When the copy
paper actuates the copier exit sensor, the exit rollers start rotating. The exit
rollers continue to rotate for 250 milliseconds after the copy paper has gone
through the paper sensor [B].

The roller drive motor [C] rotates the lower exit roller via the roller drive belt

[D]. The shaft of the lower exit roller is a cylindrical cavity type which rotates

around the transfer wheel shaft [E]. The paper sensor is positioned just in

front of the exit rollers. The paper sensor detects misfeeds in the sorter.

7.2 Roller Drive Circuit

To turn on the roller drive motor, the copier main board sends a drive signal
to the drive IC on the sorter main board. After receiving the drive signal, the
drive IC drops CN102-7 from +24 to 0 volt to turn on the roller drive motor.

When the paper sensor is actuated, CN102-13 drops to LOW. The main
board outputs three scan signals to the data select IC. The status of the sen­sor changes the resulting scan output signal. Using the scan output signal,
the copier main board determines the status of the sensor. For safety
reasons, the CPU limits the operation time of the roller drive motor to 5
seconds.

Exit Roller

The bin drive mechanism moves

the bins up and down to receive
copies under the direction of the
copier CPU.

The main com­ponents in this mechanism are the
bin drive motor [A], two transfer
wheels [B,B’], the wheel switch

[C], and the bins themselves.
Pins on either side of each bin are

inserted into slots called bin guides

[D,D’].

The bins slide up and
down in the bin guides. The bins
sit on each other with the lower bin
resting on the permanently­mounted 10th bin. The upper and
lower paper guides pivot up and
down depending on the height of
the bin to be picked up or
released.

1 August 1988

The home position switch [E] in­forms the CPU when all the bins
are lowered.

To move the bins up, the bin drive
motor turns clockwise (as viewed
from the front). A timing belt [F]
turns the transfer wheels.

The transfer wheels have two slots

in them 180 degrees apart. As the

transfer wheels turn, these slots

engage the bins and lift them up.
Each time the transfer wheels turn

180 degrees, they raise one bin.

To move the bins down, the CPU
reverses the bin drive motor and
the above processes reverses.

The CPU monitors the position of
the bins through pulses generated

by the wheel switch and the ac-

tuator cam [J]. The actuator cam

has two flat sides that are 180
degrees apart and is mounted be­hind the rear transfer wheel. A
pulse is generated each time one
of the lobes of the actuator cam
passes the wheel switch.

8.2 Bin Drive Circuit

1 August 1988

To turn on the bin drive motor, the copier main board sends drive signals to
the drive IC on the sorter main board. After receiving the drive signals, the
drive IC either raises CN102-8 or CN102-9 to + 12 volts. This turns on the bin
drive motor which respectively moves a bin up or down. The main board
monitors the output of both sorter switches through the data select IC. When
either the home position switch or wheel switch is actuated, CN102-11 or

CN102-12 drops to LOW. The main board outputs three scan signals to the
data select IC. The status of the switches changes the resulting scan output
signal. Using the scan output signal, the copier main board determines the
status of the switch.

- Service Call Condition (EA1) ­The CPU monitors the on-time of the bin drive motor to detect a malfunction

of the bin drive motor. If the bin drive motor continues to rotate more than
twelve seconds, the CPU stops machine operation and displays EA1 on the
copier operation panel.

9-11

1 August 1988

9. OPERATION PANEL CIRCUIT

As with the monitoring and the controlling of the switches and the motors, the
data select IC and the drive IC are respectively used to detect a pressed key
and to turn on the LEDs on the operation panel board.

When the Sorter key or the Bin Shift key is pressed, CN103-1 or CN103-4
drops to LOW respectively, informing the data select IC of the pressed key.

To turn on the Sort indicator LED, the Stack indicator LED, or the Check

Sorter Paper Path indicator LED, the drive IC drops either CN103-6, CN103-7,
or CN103-8 to LOW respectively.

In addition to being used for the exit roller and bin drive timing, the paper sen­sor checks for a misfeed in the sorter.

When the copier exit sensor is actuated by the copy paper, the CPU on the

copier main board starts a timing cycle. After 1,250 mini seconds, the CPU
checks whether or not the paper sensor is actuated. (J1: Paper Sensor ON
Check)

The CPU also starts a timing cycle when the paper sensor is actuated. Then
at 3.7 seconds, the CPU checks whether or not the copy paper has passed
the paper sensor. (J2: Paper Sensor OFF Check)

In misfeed condition, the “Check Sorter Paper Path” indicator on the sorter
operation panel lights and copier operation is inhibited. To recover the sorter
from the misfeed condition, the sorter has to be slid away from the copier,
then, after misfed paper removal, returned to its original position.
