In a simple copy machine, a stop signal, S, is to be generated to stop the machine operation and energize an indicator light whenever either of the following conditions exists: (1) there is no paper in the paper feeder tray. (2) the two micro-switches in the paper path are activated, indicating a jam in the paper path. The presence of paper in the feeder tray is indicated by a HIGH at logic signal P. Each of the micro-switches produces a logic signal (Q and R) that goes HIGH whenever paper passes over the switch to activate it. (3) Regardless of the state of the previous two statements. The stop signal is active if there is no internet connection to the machine, or the inside temperature sensor is active. (Note: This sensor is active if the inside temperature of the machine reaches a specific threshold temperature). (4) Regardless the previous statements. If the ink cartridge is empty, the stop signal light is on with a second indicator (second LED). Design and build the logic circuit to produce a HIGH at output signal S for the stated conditions.
