12 February 1992 BASIC OPERATION
5. BASIC OPERATION
5.1 CLEAR MODE
When the main switch of the copier is turned on, the sorter automatically
assumes a clear mode condition. It also changes to a clear mode condition if
the sort or stack mode is recalled or if the interrupt key is pressed. In a clear
mode condition, all copies are stacked on the proof tray.
Sorter operation starts when a sheet of copy paper causes the copier exit
sensor to be de-actuated. At this time the roller drive motor energizes. The
roller drive motor de-energizes when the paper exits the copier and the paper
sensor is actuated. The paper senso r signa l is sent to the copie r through an
interface board to check for paper misfeed. The wheel drive motor does not
turn on when in the clear mode.
5.2 SORT MODE
After the sort mode is selected by pr e ssing the Sorter key, the wheel drive
motor turns on to move the proof tray up. When the first sheet of paper
activates the copier exit sensor, the roller drive motor turns on. Shortly after
the paper sensor turns off (420 ms later), the wheel drive motor turns and
advances the bins one step. When t he whee l senso r is acti vat ed , th e whe el
drive motor turns off.
5.3 STACK MODE
As in the sort mode, the roller drive motor turns on when the first sheet of
paper actuates the copier exit sensor. All copies of the copy run are then fed
to the first bin. When the final copy passes the paper sensor, the wheel drive
motor turns on and advances the bins one step.
There are no limits on the number of copies that can be entered up to the full
999 copy limit of the copier. However, the physical capacity of the bins is a
good deal less. (See "Bin Capacity" in the specifications.)
When all 20 bins have been used, the wheel drive motor turns on until all the
bins have been lowered (including the proof tray).

BIN DRIVE MECHANISM 12 February 1992
7. BIN DRIVE MECHANISM
[A]
[G]
[C]
[D]
[I]
[H]
[B]
[F]
[E]
The bin drive mechanism moves the bins [A] up an d do wn to re ceive copie s
under the direction of the copie r CPU. The ma in comp onents in this
mechanism are the wheel drive motor [B], the two transfer wheels [C], the
wheel sensor [D], and the bins themselves.
Pins on either side of each bin are inserted into slots in the sorter side frame.
The pins slide up and down in these slots. The bins r est on ea ch ot her with
the lower one resting on the lift bar [E ]. The spr ings [F], on either end of the
lift bar, lift it up forcing the bin pins against the transfer wheels. Plastic
spacers [G] on both ends of the bin keep the bins separated.
To move the bins up, the bin drive motor turns clockwise (as viewed from the
front). A timing belt [H] turns the transfer wheels [I].

[A]
[B]
[C]
[E]
[D]
The transfer wheels have two slots in them 18 0 de gr e es ap ar t . As th e
transfer wheels turn, these slots en gage the pins of the bins and lift them up.
Each time the transfer wheels tu r n 18 0 de gr e es, the y ra ise on e bin .
The CPU counts the bins using the wheel sen sor . A cylindr ica l ac tu at or on
the front transfer wheel turns the wheel sensor on and off. This actuator has
two notches that are 180 de grees apart. The wheel sensor turns on each
time one of the slots passes through the sensor.
To move the bins down, the CPU reverses the bin drive motor and the above
process reverses.
The home position sensor [A] is locat ed at th e lowe r re ar en d of the sor te r .
When all the bins are lowered, the lift bar [B] presses down on the actuator
[C], actuating the sensor. The CPU checks the sensor whenever the power is
turned on. At this time, if the bins are not in the home position, the home
position sensor is deactuated the CPU will return the sorter bins to the home
position.
The mounting position is about 18.5 degrees off between the front tran sfe r
wheel [D], and the rear transfer wheel [E]. Therefore, the front and rear of the
bins do not rise simultaneously thus avoiding unusual noises and also
reducing load.

BINS 12 February 1992
8. BINS
[A]
[B]
The proof tray and the twenty bins are all basically the same. Formed out of
thin flexible steel plate, they ha ve spa cer s on the left end to hold them apart
and pins at the front and rear of the right end, which are inserted in guide
slots in the sorter frame.
On the right edge, the bins have stoppers [A] which prevent copies from
sliding back into the sorter after they have been fed out. The pattern of these
stoppers is different for even and odd numbered bins.
Three leaf springs [B] on the underside of each bin hold the copies flat in the
underlying bin.

12 February 1992 EXIT ROLLERS
9. EXIT ROLLERS
[A]
The exit roller shaft is hollow and is mounted on the transfer wheel shaft [A]
(coaxial). When the copy actuates the copier’s exit sensor, the CPU sends a
signal to the sorter to turn on the roller drive motor. The roller drive motor
turns off at the same time as the copier main motor.
