6) Start of 2nd 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 document feed
motor (M37) also starts to rotate in reverse. (The large original exit solenoid (SOL5) 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 (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. If
not, the tray lift motor (M38) starts to rotate to lower the tray and the original set signal turns OFF.
The tray lift motor (M38) stops rotating when the lifting tray lower limit detection sensor (S62) 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 (M36, M39) start to accelerate.
When the trailing edge of the original has passed the 4th roller then proceeded a specified distance,
the large original exit motor (M39) starts to slow down and the read motor (M36) stops rotating.
The large original exit motor (M39) stops rotating when the trailing edge of the original has been
detected by the large original exit sensor (S68) then proceeded a specified distance. The large orig-
inal exit solenoid (SOL5) turns OFF and the operation ends when the original has been discharged.
