(5) Start of 1st original 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.
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.
Feeding of 2nd original begins when the trailing edge of the original has passed the 4th roller.
