16. 5. 5. Single-sided feeding at mixed-original mode
(Operational condition: A4-R and FOLIO originals/Reproduction rario: 100%)
(1) Original setting
Same operation as 16.5.1.(1)
(2) Lift of the lifting tray
Same operation as 16.5.1.(2)
(3) Start of separation
Same operation as 16.5.1.(3)
(4) Start of feeding
The feed motor starts to rotate in reverse. After the feed motor has finished accelerating, the read motor
starts to rotate forward.
Both the feed and read motors start to slow down when the leading edge of the original has come to a
specified distance before the read sensor.
The original is transported a specified distance by the read motor after the read sensor detects the
leading edge of the original. Then after the original size is detected and the idle reversing is judged to
be necessary, both the feed and read motors start to accelerate and the large original exit solenoid
turns ON.
The large original exit motor starts to rotate in reverse when the leading edge of the original has been
transported to the large original exit side and passed the 3rd roller.
When the registration sensor detects the trailing edge of the original, the feed motor stops rotating and
the tray lift motor starts to rotate to lift the tray. Then the tray lift motor stops lifting the tray when a
specified number of counts is counted after the upper limit sensor has detected the top side of the
original.
The empty sensor detects whether or not there is a next original when a specified time passes after the
the registration sensor has detected the trailing edge of the original. With a next original, separating
begins. Without it, the tray lift motor starts to rotate to lower the tray and the original set signal is reset.
The tray lift motor stops rotating when the lower limit sensor has detected the tray.
