If the sensor (leading edge sensor (PS801) or delivery sensor (PS803), or delivery paper width sensor (PS804)) detects a paper at the start of initial rotation, CPU
judges as the residual jam at startup.
When there is paper in inside the machine, the leading edge sensor flag is pushed up with paper, and paper having is judged.
