Three Stage Normal In three stage normal mode the upline auxiliary conveyor transports Board 1 to
the print station conveyor where the board is processed. With Board 1 in print
position, Board 2 is dispensed from the upline machine. When Board 2 arrives
at the sensor, at the end of the upline auxiliary conveyor, the transport belts stop.
After the print cycle, the Board 1 is then transported to the downline auxiliary
conveyor. When the leading edge of the board activates the sensor, at the end
of the downline auxiliary conveyor, a signal is sent allowing Board 2 to enter the
print station and Board 3 to enter on the upline auxiliary conveyor.
Providing the downline machine is ready, the first board can leave the downline
auxiliary conveyor and the cycle be repeated. If the downline machine is busy,
the second board is printed and transported to the end of the print station

conveyor where it is held by the conveyor board stop.
Three Stage Fast In three stage fast mode, the operation is the same as three stage normal mode
with one exception. The second board is transported on to the print station
when the trailing edge of the first board passes the board at right opto situated
at the end of the print station conveyor. This is achieved by the downline
conveyor returning a ‘Busy’ signal back to the centre as soon as it detects that
its ‘Board Available’ input has gone ‘low’, which completes a downline transfer
as far as the print station is concerned.
