Symbol Name Function Index No.
Motors
M1 Roller Drive Motor DC motor that energizes to drive the lower
exit rollers.
M2 Bin Drive Motor Reversible DC motor that energizes to move
the bins up or down.
Switches
SW1 Wheel Switch Detects the rotation of the transfer wheel
and stops it in the correct position.
SW2 Sorter Switch Reed 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 sorter.

Sorter Main Board (PCB1)
Copier Main Board (PCB1)
The copier main board provide s +24 volt s (VA) and +5 volts (VC) to the sorter
main board. +24 volts powers the roller drive motor, and +5 volts po wers 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 t he drive and che cks t he stat us of the sorte r
via the sorter main board. The copie r main bo ard send s the scan sign als to
the data selected IC on the sorter main board. After receiving the scan
signals, the data select IC outputs th e sta tu s of th e sensor an d switch es as
the scan output signal.
The copier main board also sends the sorte r drive signal to the drive IC on
the sorter main board. Af te r receiving the drive signal, the drive IC turns on
the appropriate motors.

1 May 1993 BASIC OPERATION
5. BASIC OPERATION
– Clear Mode –
When the main switch of the copier is turned on, the sorter automatically
assumes the clear mode. In this mo de, all copies are stacked on the first bin.
The sorter also assumes the clear mod e whe n eit he r the inte rrupt mode or
the manual feed mode is selected.
Sorter operation be gin s wh en a copy act ua te s t he copie r e xit sen sor. At this
time, the roller drive motor energizes. Whe n the paper exits onto the sorte r
bin, the paper sensor is de-activated and the roller drive motor is then
de-energized. The copier main board monitors the paper sensor through the
sorter main board to check for pape r misfee ds.
– Sort Mode –
Pressing the Sorter ke y once shifts the copier to the sort mode . In this mode,
all copies of the first original are delivered to separa te bins sta rtin g from the
top. The copies of the second original are delivered to th e same bins, but
starting from the bottom. The cop ies of the third origin al sta rt from the top and
so on. The bin drive motor turns on to advance th e bin one step , 25 0
milliseconds after the copy has gone th rou gh the pape r sen sor. If th e Cop y
Quantity, Clear/St op , Book Copy, or Sorter key is pressed durin g th e sort
mode, all bins shift to the ho me po sition.
– Stack Mode –
Pressing the Sorter ke y twice shif ts the copier to the stack mode. In th is
mode, all copies of the first origina l are de livere d to the first bin , all copies of
the second original are delivere d to the secon d bin , an d so on. The bin drive
motor turns on to advance the bin one ste p, 250 milliseconds after the last
copy of the original has gone through the pap er sen sor. If th e Sorter key is
pressed during stack mode, all bins shif t to home posit ion.
