How the designated original is copied in the duplex
original to duplex copy mode
In the duplex original to duplex copy mode, although the
original designated with the cover or chaptering mode is
always copied on the front side of the cover or slip
sheet, it is copied during the second original feeding
cycle, not during the first one. This is because the cover
or slip sheet must enter the duplex tray if the designated
original is copied during the first original feeding cycle.
To allow this, the original recirculating motion in this
mode is different from that in the duplex original to
duplex copy mode without the cover or chaptering
mode, as follows:
1.
During the 1st Original Feeding Cycle
The front side of the originals set in the RDH is
copied as usual. However, the designated original
is not copied during this cycle. Before the
designated original feeds out to the stack feed
table, it is not inverted. As a result, the front side
(image side) of the designated original only faces
the direction of the reverse side of the other
originals and stacked in the stack feed table.
2.
During the 2nd and the Following Original
Feeding Cycle
During the 2nd cycle, the reverse side of the
originals is copied. The designated original is
copied during this cycle. The completed duplex
copies are delivered to the shift tray. As the copy
image on the cover or slip sheet is made while the
reverse side of the other originals is copied, only
the cover or slip sheet is inverted in the finisher to
stack all copies in page order.
For the following cycles, both sides of the originals,
including the designated original, are copied as
usual in the duplex original to duplex copy mode
until all the desired copy sets complete. Even
during this period, only the cover or slip sheet is
inverted in the finisher to stack all copies in page
order.
