5. BASIC OPERATION

- Clear Mode -
When the main switch of the copier is turned on, the sorter automatically
assumes a clear mode condition. It also changes to clear mode if sort or
stack mode is recalled or if the interrupt key is pressed. In clear mode, all
copies are stacked on the proof tray.
Sorter operation starts when the copier sends the paper feed signal to the
selected paper feed station. 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 (lifted up). The paper sensor signal is sent to the
copier through an interface board to check for a paper misfeed. The wheel
drive motor does not turn on when in clear mode.
- Sort Mode -
After sort mode is selected by pressing the Sorter key, the wheel drive motor
turns on to move the proof tray up. The start timing of the roller drive motor is
the same as in clear mode. At 250 ms after the paper sensor turns off, the
paper is safely in the bin, so the wheel drive motor turns and advances the
bins one step. When the wheel sensor is de-activated, the next bin is in
position, so the wheel drive motor turns off.
- Stack Mode -
As in clear mode, the roller drive motor turns on when the copier sends the
paper feed signal to the selected paper feed station. All copies of the copy
run are then fed to the first bin. At 250 ms after 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).
