(10) Start of 2nd original top side scanning
Scanning begins after receiving the original transport signal from the copier. At the same time the
original stop signal is reset. When the read motor starts to rotate forward, the feed motor also starts to
rotate in reverse. (The large original exit solenoid has been ON from 1st original.)
The SCN-STR turns ON when the leading edge of the original has reached the scanning section.
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 come to the 3rd roller.
When the registration sensor has detected the trailing edge of the original, the feed motor stops rotating
and the tray lift motor starts to rotate to lift the tray. The tray lift motor stops rotating when a specified
number of counts is counter 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
registration sensor has detected the trailing edge of the original. If not, 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.
When the trailing edge of the original has passed the scanning section, the SCN-STR turns OFF and
both the read and large original exit motors start to accelerate.
The large original exit motor slows down when the trailing edge of the original has passed the 4th roller
and proceeded a specified distance. After the large original exit sensor has detected the trailing edge of
the original, the read motor stops rotating soon and the large original exit motor stops rotating when the
original has proceeded a specified distance. Then the original is nipped by the large original exit roller.
