(2) Operation of Double-Sheet 2-Sided Copying
1. The first sheet of paper is taken up and fed in and the image of the second page is printed.
2. Just before the 1-sided copy moves past the Paper Exit Roller, the direction of rotation of the Paper Exit
Roller is reversed and the 1-sided copy is transported towards the Duplex Unit. At the same time, the
second sheet of paper is taken up and fed in.
3. At the same time when the image of the fourth page is printed on the second sheet of paper, the first 1-
sided copy is transported through the Duplex Unit. Because of the Duplex paper take-up timing
involved, the first 1-sided copy is temporarily stopped at a point 20 mm before the Manual Feed Take-
Up Roll; but it is soon fed out of the Duplex Unit.
4. The image of the first page is printed on the first 1-sided copy fed out of the Duplex Unit. At the same
time, the second 1-sided copy is reversed at the paper exit section of the machine and transported
towards the Duplex Unit. It is then fed out of the Duplex Unit without being stopped.
5. The image of the third page is printed on the second 1-sided copy.
6. As the second 2-sided copy is fed towards the paper exit section of the machine and as it is being fed
out of the machine, the third sheet of paper is taken up and fed in for the printing of the image of the
sixth page.
(Steps 2 through 6 are then repeated.)
