6.1 Paper Path

1.
After receiving a print command, the printer feeds paper from the main cassette or the bypass tray.
2. The paper being fed passes the paper feed sensor. (Jam 0 occurs if the sensor is not actuated within a specified
amount of time).
3.
Having passed the paper feed sensor the paper moves to the paper exit sensor via the print process. (Jam 1
occurs if the sensor is not actuated within a specified amount of time)
4.
The paper then passes through the paper exit sensor and out of the system. (Jam 2 occurs if the trailing edge of
the paper does not pass the exit sensor within the specified time between the papers leading edge activating the
exit sensor).
