DC motor that energizes to drive the lower
exit rollers.
Reversible DC motor that energizes to move
the bins up or down.
Detects the rotation of the transfer wheel
and steps it in the correct position.
Read switch that becomes activated when
the sorter is in the proper position (aligned
next to the copier). Also works as a jam
reset switch for the setter.
Informs the CPU that all the bins are
lowered.
Serves as the misfeed sensor for the sorter
and also sets exit roller and bin drive timing.
Serves as the communication board between the copier main board and the sorter.
Contains the Sorter key and Sorter Misfeed
indicators.

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.

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.
