     A broken-paper sensor circuit is set up in controller of motor and signal is input from LED at paper entrance. More comparators are serially connected and a multivibrator is cross indicator lamp to make the indicator lamp light in different states for indicating different working conditions. A paper-feed driver controls motor to rotate forward to breaking off paper. A paper-jam sensor circuit can stop motor and a backlash driver can drive motor to rotate reversely for drawing jammed paper back.
