During the Last Original Feeding Cycle
After completing the copy run, one more original
feeding is done. This is to return the designated
original, which had been made side down during
the first original feeding cycle, into the original
setting. (The designated original is inverted before
it feeds out to the stack feed tray, and the other
originals are not.)
As a result, the original feeding is twice the desired
number of copy sets, plus one.
Other special motions
When the back cover sheet mode is selected, the
copying speed during the first original feed cycle
becomes half of normal copying speed. This is because,
at normal copying speed, the copier cannot catch up
with the switching to a cover sheet from the normal
paper when the last original is detected. When the last
original is detected while the paper is being fed, the
paper for the last original is already fed.
In the back cover sheet mode, the originals are
intermittently fed only for the first feed cycle, resulting
the copying speed being reduced by half. Therefore, the
copier can stop feeding the paper after the last original is
detected. It switches to a cover sheet. After the first
original feed cycle, the number of originals is known. For
a continuous copy run, the copying is done at normal
speed because the copier can stop feeding the normal
paper and feed a cover sheet for the last original.
