(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. With 1st original, 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.
From 2nd original, the feed motor starts to slow down when the leading edge of the original has come
to a specified distance before the 1st roller. The feed motor stops rotating when the original length
sensor has detected the trailing edge of the original. At the same time, the tray lift motor starts to rotate
to lift the tray. When the tray has come to a specified level after the upper limit sensor had detected the
top side of the original, it stops rotating.
The empty sensor detects whether or not there is a next original with a specified delay after the original
length sensor has detected the trailing edge of the original. Without a next original, the tray lift motor
starts to lower the tray to turn the origianl set signal OFF. When the lower limit sensor has detected the
tray, it stops rotating. With a next original, the separation begins at the same time the scanning begins.
When the original has been transported a specified distance by the read motor after the read sensor
had detected the leading edge of the original, the read motor stops rotating and the original stop signal
turns ON.
(5) Start of 1st original scanning
The scanning begins after receiving the original transport signal from the copier. At the same time, the
original stop signal is reset. Then the read motor starts to rotate forward and to separate the next
original.
The SCN-STR turns ON when the leading edge of the original has reached the scanning section. When
it has been transported to the intermediate transport section and come to a specified distance before
the intermediate transport roller, the large original exit motor starts to rotate in reverse.
Feeding of 2nd original starts when the original has been transported a specified distance by the read
motor after the original length sensor had detected the trailing edge of the original.
