(5) Start of 1st 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 and the large original exit solenoid turns ON. 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 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
registration sensor has detected the trailing edge of the original. With a next original, separating of the
next original begins.
