Media out detection
This function checks whether media is loaded in the HCF media tray.
When media is present, the media out actuator in the middle of the HCF is raised by the lifting of media and
leaves the sensing area of the sensor (media out), which makes the sensor light-receivable. Presence of media
is detected.
On the other hand, if media end occurs when the HCF media tray is at the feeding position, the media out
actuator comes inside the sensing area of the sensor (media out), which blocks the light transmission of the
sensor (media out). Media out is detected.
If the HCF media tray is not lifted, the media out actuator remains in the sensing area of the sensor (media out),
while blocking the light transmission of the sensor (media out). Media out is detected regardless of the presence
of media in the tray.
Detection of media out is carried out at every constant period after the lifting operation is completed.
When media out is detected, media transfer from the HCF is inhibited.
