The JAM sensor is a detection switch for determining whether the recording paper edge is in the correct position or not. If the
recording paper cannot be detected correctly at the JAM sensor position even when recording paper is present, then JAM is
displayed. If the recording paper is at the sensor position, then the switch turns on the CN1-11pin (Analog) switches to a high level.
