4. ELECTRICAL OPERATION

- AC -
AC power from the wall outlet passes through the sorter stapler connector
unit to the sorter stapler connector motor and to the second sorter stapler.
When the main switch of the copier is turned on, the copier provides AC
power 100V to the first sorter stapler.
The main PCB of the first sorter stapler then energizes the power relay (RA1)
of the sorter stapler connector unit, and AC power is provided to the second
sorter stapler and sorter stapler connector motor.
When the copy paper is detected by the exit sensor of 1st sorter stapler, the
main PCB of the first sorter stapler sends a signal to the connector unit that
closes the SSR AC circuit and starts the connector unit motor. The Vertical
cover safety switch (SW1) and the Horizontal cover safety switch (SW2) also
close when this signal is sent.
The sorter stapler transfers the sort, stack, and stapler command data to the
second sorter stapler over fiber optics cables. The second sorter stapler then
sends a feed back signal (Jam, Ready, or stapler end) to the first sorter
stapler.
