System Overview
3.3.13 Checking Paper jam
Paper Jam happens when a paper is not fed to required position by a mechanical obstacle.
The paper jam is decided by checking the states of sensors while moving the paper. There are a feed sensor and an exit sensor in the
The jam is classified to 3 types according to the position of the paper.
3.3.13.1 Paper Jam 0
This is the status that the paper doesn’t arrive in the feed sensor. If the feed sensor is not activated within the speci- fied time after
3.3.13.2 Paper Jam1
This is the status that the paper is jammed between the feed sensor and the exit sensor. If the feed sensor is active or the exit sensor is not active after the specified time from activating the feed sensor, the engine decides the paper is jammed. Also, if the status (the exit sensor and the feed sensor are active) is maintained, the engine decides the paper is jammed by the structure of the mechanism after the specified time. So the engine informs the error status of the main system and the error message is displayed at LCD window informing the error status of the user. The specified time or steps will be decided based on the mechanical design length and the paper size. When Paper Jam1 happens, fuser and fan is off.
3.3.13.3 Paper Jam2
This is the status that the paper is jammed after it passes the exit sensor. If the exit sensor is still active after the specified time from activating exit sensor, the engine decides the paper is jammed. So the engine informs the error status of the main system and then the error message is displayed at LCD window informing the error status of the user. The specified time or steps will be decided based on the mechanical design length and the paper size. . When Paper Jam2 happens, fuser and fan is off.
