1.5 BASIC OPERATION

- Introduction -

Sorter operation begins when the copier exit sensor turns on. At that time, the
sorter motor turns on and the rollers start turning.

The sorter has two paper transport speeds. When the sorter motor turns on, it
rotates at slow speed of 220 mm/s. This is the slightly faster than the copier’s
transport speed. When the trailing edge of the paper passes the copier exit
sensor, the sorter shifts to high speed which is about 550 mm/s. When the
trailing edge of the paper passes the jam sensor, the sorter shifts again to
slow speed.

When the copier main motor turns off, the sorter motor also turns off.

- Clear Mode -

The copies pass from the copier’s exit through the relay guide plates to the
turn gate. The turn gate directs the paper to the vertical guide unit. The
vertical drive rollers then move the paper up until it reaches the turn guide.
The turn guide directs the paper to the first bin. During transport of the copies
in this mode, none of the bin gates are used.

- Sort Mode -

When in sort mode, the first sheet is placed in the first bin in the same way as
when in clear mode.

The second and subsequent copies follow the same path but are directed to
the bins in order from top to bottom (second copy to second bin, third to the
third bin, and so on). The appropriate bin gate solenoid turns on when the
leading edge of the paper activates the inlet sensor and turns off when the
trailing edge of the paper passes the jam sensor.

If 11 or more is entered while in sort mode, the message display will indicate
"Sort max.: 10 sets", the Copy Quantity indicator will display 10, and the Max
indicator will blink. (The Start key remains green.)

- Stack Mode -

When in stack mode, all sheets of the first copy run go to the top bin just as in
clear mode. When the Start key is pressed again, the entire second run is
directed to the second bin. Similarly, the third run goes to the third bin, the
fourth run to the fourth bin.

If the mode is not changed, the sorter will continue in this way, sending all
copies from a single run to one bin and dropping down one bin each run until
there are copies in all 10 bins. Upon completion of the copy run to the 10th
bin, copying will stop and the guidance display will indicate "Sort max.: 10
sets". The Max indicator will blink. (The Start key remains green.) The
operator can copy 11th or more originals continuously when pressing the
start key again. These copies run to the top bin and drop down one bin each
run, as described above.

If on any single copy run, the operator enters a number greater than 40 (the
maximum bin capacity for stack mode), the message display will indicate
"Stack max.: 40 sheets", the Copy Quantity indicator will display 10, and the
Max indicator will blink. (The Start key remains green.)

- Interrupt Mode -

[A]

If the Interrupt key is depressed during a multicopy run, the sorter continues
to place copies in the correct bins until that copy run is finished. Which bin
the copies go to depends on the mode: sort, stack or clear mode.

Then, the operator presses the Start key to make interrupt copies. As each of
the interrupt copies enters the sorter, the sorter CPU energizes the interrupt
bin solenoid [A] and the copies are directed to the interrupt bin.

When the interrupt mode is canceled, the previous settings and modes are
returned to resume the previous copy run that was interrupted.

- Sorter Misfeed -

The sorter CPU starts the misfeed timing count when the inlet sensor turns
on. If the copy is not fed into the bin within a specified period (different for
each bin) the sorter CPU will send a misfeed signal to the copier. The copier
will then light the Sorter Misfeed indicator and stop operation. (Any copies in
the paper path at the time will be finished first.)

The sorter CPU directs any copies that are being processed in the copier at
the time of a sorter misfeed to the interrupt bin. It also corrects the copier
Copy Counter indicator so that it displays only the number of copies actually
in the top 10 bins. After removing the misfed paper, the misfeed condition is
automatically cleared when the sorter cover is opened and closed.

The sorter motor [A] is a servo motor and it is controled by the sorter CPU.
The sorter CPU also controls the motor rotation speeds: slow and high.
