Paper Eject
The completion of paper eject is detected in the following manner:
(a)
When the leading edge of the paper push down the eject sensor actuator
located in the fixing unit, the photo sensor (photo interrupter) is opened and
detects the start of paper eject motion.
(b)
After that, when the bottom of the edge of paper has passed through the
paper eject sensor actuator, the photo sensor is closed and the completion
of paper eject motion is recognized.
