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.

The exit rollers [A] take over pape r tra nsp ort from the copier. When the copy paper actuates the copier exit sensor, the exit rollers start rotatin g. The exit rollers continue to rotate for 2 50 millise con ds af te r the copy pape r has go ne through th e pa per sensor [B].

The roller drive motor [C] rotates the lower exit roller via the rolle r drive belt [D]. The shaft of the lower exit roller is a cylindrical cavity type which rotates around the transfer whee l shaf t [E]. The paper sensor is positioned just in front of the exit rollers. The paper sensor detects misfeeds in the sorter.

To turn on the roller drive motor, the copier main board sends a drive signal to the drive IC on the sorter main board. Aft er receiving the drive signal, the drive IC drops CN102-7 from +24 to 0 volt to turn on the roller drive moto r.
When the paper sensor is actu at ed , CN102-13 drops to LOW. The cop ier main board outputs th ree scan signals to the data select IC. The sta tus of the sensor changes the resulting scan output signal. Using the scan output signal, the copier main board dete rmine s the stat us of the senso r. 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 dire ctio n 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 permanently-mounted 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 May 1993 BIN DRIVE
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 ap art . 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 actuator cam [J]. The actu at or 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 actu ator cam passes the wheel switch.

To turn on the bin drive motor, the copie r ma in board sends drive signals to the drive IC on the sorter main board. After receivin g the drive signa ls, the drive IC either raises CN102-8 or CN102-9 to +12 volts. This tu rns on the bin drive motor which respectively moves a bin up or down. The sorter main board monitors the output of bot h sorter switches through the data select IC. When either the home position switch or wheel switch is actuat ed, CN102-11 or CN102-12 drops to LOW. The copier main board outputs three scan signals to the data select IC. The stat us of the swit che s chan ges the resulting scan output signal. Using the scan output signal, the copier main board determines the status of the switch.
The CPU monitors the on-time of the bin drive motor to dete ct a malfun ctio n of the bin drive motor. If the bin drive mot or con tin ue s to rot at e more than twelve seconds, the CPU stops machine operation.

In addition to being used for th e exit roller and bin drive timin g, the paper sensor checks for a misfeed in th e sort er. The copier CPU checks whether the paper sensor is actuated within 942 pulses (3.8 seconds) after the registration clutch turn s on (at 2,000 pulse s). (J1: Pap er Sensor ON Check)
Also, the copier CPU starts a timing cycle when the paper sensor is actuated. Then, at 2.75 (A4 sideways) or 2.8 0 (Le tt er sideways) seconds, the CPU checks whether the cop y pap er ha s passed through the paper sensor. (J2: Paper Sensor OFF Check)
In misfeed condition, the "Check P aper Pa th " and "Misf eed Lo cat ion " indicators lights and copie r o peration is inhibited. To recover the sort er from the misfeed condition, th e sort er has to be slide awa y from th e cop ier, then, after misfed paper removal, ret urned to its original position.
