1)After receiving a print command, the printer feeds paper from the main cassette or manual feeder as required.

2)The paper being fed passes the paper feed sensor. (Jam 0 occurs if the sensor is not operated within a certain time)

3)Having passed the paper feed sensor the paper moves to the paper exit sensor via printing process. (Jam 1 occurs if the sensor is not operated within a certain time)

4)The paper then passes through the paper exit sensor and out of the set. (Jam 2 occurs if the trailing edge of the paper does not pass the exit sensor within a certain time of the paper leading edge activating the exit sensor)
