4) Start of feeding
The document feed motor (M37) starts to rotate in reverse. When the document feed motor (M37)
has completed acceleration, the read motor (M36) starts to rotate forward. Both the document feed
and read motors (M37, M36) start to slow down when the leading edge of the original has come to a
specified distance before the read sensor (S69).
They stop rotating and the original stop signal turns ON when the leading edge of the original has
been detected by the read sensor (S69) then proceeded a specified distance.
5) Start of 1st original scanning
Scanning begins after receiving the original transport signal from the engine. At the same time the
original stop signal is reset. When the read motor (M36) starts to rotate forward, the feed document
motor (M37) also starts to rotate in reverse and the large original exit solenoid (SOL5) turns ON. The
SCN-STR turns ON when the leading edge of the original has reached the scanning section.
The large original exit motor (M39) 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 original registration sensor (S55) has detected the trailing edge of the original, the docu-
ment feed motor (M37) stops rotating and the tray lift motor (M38) starts to rotate to lift the tray. The
tray lift motor (M38) stops rotating when a specified number of counts is counted after the lifting tray
upper limit detection sensor (S59) has detected the top side of the original.
The original empty sensor (S60) detects whether or not there is a next original when a specified time
passes after the original registration sensor (S55) 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 (M36, M39) start to accelerate.
