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 sensor signal is sent to the copier 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 pressing 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 the wheel sensor is activated, the wheel
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).
