ORIGINAL FEED
2) The original passes over the
exposure glass [A] and feeds
into the feed-out unit.
3) The original is directed onto
the exposure glass again by
the inverter pawls. The belt
drive motor now reverses 85
milliseconds after the feed out
sensor [B] turns on. The
transport belt then moves the
original toward the original
scale.
When the original leading
edge reaches the original
scale, the belt drive motor
stops. At the same time, the
feed-out motor and the
inverter solenoid turn off.
4) After the reverse side of the
original is exposed, the belt
drive motor, the feed-out
motor, and the inverter
solenoid turn on, and the
original is fed into the inverter
section. (This is the same as
step 2 above.)
5) The original is fed onto the
exposure glass again as in
step 3 above. The front side
of the original is then copied.
6) After the front side of the
original has been exposed, the
original is fed out from the DF.
