Name Function Index No.

Motors

Roller Drive Motor A DC motor that drives the lower exit rollers. 4 Bin Drive Motor A reversible DC motor that to moves the bins up or

down.

Switches

Wheel Switch Detects the rotation of the transfer wheel and stops it

in the correct position.

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.

Home Position Switch Informs the CPU that all the bins are lowered. 7

Sensor

Paper Sensor Serves as the misfeed sensor for the sorter and also

sets exit roller and bin drive timing.

Printed Circuit Board

Sorter Main Board Serves as the communication board between the

copier main board and the sorter.

OVERALL MACHINE CONTROL 31 October 1995

4. OVERALL MACHINE CONTROL

A490D500.wmf

The copier main board provide s +24 volt s (VA) and +5 volts (VC) to th e sort er main board. +24 volts powers the roller drive motor, and +5 volts po wers all sensors and switches. Also, the regulator IC changes +2 4 volt s to +12 volts, which powers the bin drive motor.

The copier main board controls t he sorter drive and checks the status of the sorter via the sorter main board. The copier main board sends the scan signals to the data select IC on th e sort er main board. After receiving the scan signals, the data sele ct IC ou tp uts the status of the senso r a nd switches 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 turn s on the appropriate motors.

31 October 1995 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 in 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 mo de. 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/Stop , Bo ok Cop y, or Sorter key is pressed when sort mode has been selected, all bins shift to the home po sitio n.

– Stack Mode –

Pressing the Sorter ke y twice shif ts the copier to the stack mode. In this 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 when stack mode has been selected, all bins shift to home position.

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.

6.2 ROLLER DRIVE CIRCUI T

A490D503.wmf

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. Th e 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. The CPU limits the operation time of the ro ller drive motor to 5 seconds.

G : Exit Roller H : Upper Paper Guide I: Lower Paper Guide

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.

31 October 1995 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 process 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.
