3) Start of separation
The document feed motor (M37) starts to rotate forward. When the original length detection sensor
(S63) detects the leading edge of the original, the tray lift motor (M38) starts to rotate to lower the
tray to a specified level.
The document feed motor (M37) stops rotating when the original has been transported a specified
distance after the original registration sensor (S55) had detected the leading edge of the original.
From 2nd original, feeding starts after the admission signal to start feeding is received.
4) Start of feeding
The document feed motor (M37) starts to rotate in reverse. After the document feed motor (M37)
has finished accelerating, the read motor (M36) starts to rotate forward. With 1st original, both the
document feed and read motors (M37, M36) start to slow down when the leading edge of the origi-
nal has come to a specified distance before the read sensor (S69).
From 2nd original, the document feed motor (M37) starts to slow down when the leading edge of the
original has come to a specified distance before the 1st roller. The document feed motor (M37) stops
rotating when the original length detection sensor (S63) has detected the trailing edge of the origi-
nal. At the same time, the tray lift motor (M38) starts to rotate to lift the tray. When the tray has come
to a specified level after the lifting tray upper limit detection sensor (S62) had detected the top side
of the original, it stops rotating.
The original empty sensor (S60) detects whether or not there is a next original with a specified delay
after the original length detection sensor (S63) has detected the trailing edge of the original. Without
a next original, the tray lift motor (M38) starts to lower the tray to turn the original set signal OFF.
When the lifting tray lower limit detection sensor (S62) 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 (M36) after the read
sensor (S69) had detected the leading edge of the original, the read motor (M36) stops rotating and
the original stop signal turns ON.
