Ricoh Aficio 401 Operating Instructions Manual page 70

For the 3-bin sorter, the options are as follows:
Reverse - specifies that the output is face-up and in ascending page
order. When you select this option, the host input data is rasterized
and stored in the order received. The data is then retrieved from the
HDD and printed so that the output is delivered face-down in the cor-
rect page sequence from page one to the end. When multiple originals
are requested, the output consists of sets of originals in the correct
page sequence (for example, three sets each in 1,2,3,4,5 page order).
Normal - specifies that the data is printed immediately in the order
received by the printer and delivered face-down. You use the Normal
option to obtain high speed printer performance. When you select this
option, the host input data is rasterized and printed immediately, so that
the output is in the sequence received by the printer and delivered face-
down. When multiple copies are requested, the output consists of a set
of copies of each page (for example, three sets each in 1,1,1; 2,2,2;
3,3,3 page order).
Duplex - specifies that the data is printed on both sides of each page,
face-up, in the order received by the printer. When you select this op-
tion, the host input data is rasterized. The odd numbered pages are
stored in the HDD and the even numbered pages are printed and
stacked in the duplex tray. When this process is complete, the odd
numbered pages are retrieved from the HDD and printed on the reverse
side of the stacked even numbered pages in reverse order, so that the
output is delivered face-up in the order received by the printer. You
can not print more than 50 originals at one time in this mode.
The default is Reverse.
