(3) Switchback/refeed system<br />
Paper that has already being fixed in the fuser unit on its first (front) side will be conveyed along the guide towards the facedown<br />
tray via the turning of the fuser unit’s lower exit roller. At this point, the fuser unit’s upper exit roller is turning in a<br />
forward direction and, in the case of 1-sided printing, the paper will be ejected onto the face-down tray through the normal<br />
action of that upper exit roller. However, in the case of duplex (2-sided) printing, once a specified amount of time has<br />
elapsed after the trailing edge of the paper turns off the exit sensor actuator (located inside the fuser unit), the fuser unit’s<br />
upper exit roller will begin to turn in the opposite direction in order to reverse the direction of the paper feed. Then, the<br />
operation of the change guide and the direction of rotation of the lower exit roller will be applied to stop the paper from being<br />
fed back inside the fuser unit and, instead, will guide the paper into a section below the fuser unit. Next, after the paper has<br />
turned on the lower exit sensor actuator, that paper A will be fed to the conveying roller. Once the paper reaches the<br />
conveying roller, it will be fed towards the refeed roller through the action of the conveying roller. Once the paper reaches<br />
the refeed roller, it will be fed via the turning of that roller and, at the point that it turns on the registration sensor, the initial<br />
feeding (refeeding) operation of the second (rear) side is complete.<br />
