Internal Finisher SR3130 (D690)
2.1.2 MECHANISM
Straight paper ejection mechanism
Paper ejected from the printer unit is transported by a transport roller and eject roller via an entrance roller. These are driven by entrance motor, transport motor and eject motor which permit linear speed correspondence. The paper exit driven roller stands by at a certain distance from the paper exit roller, and its descent/ascent is performed by an eject guide plate movable motor depending on the detection timing of the sensors (motor operates CW/CCW).
The paper eject open/close guide plate descent/ascent timings are as follows:
Descent: Paper rear edge passes entrance sensor
Ascent: Paper rear edge passes transport sensor
The eject guide plate is provided with a Home Position sensor which detects the home position during ascent.
