Tables 3-401 and -402 show the sensors used to monitor the feeding of copy paper, and Figure 3-401
shows the arrangement of these sensors.

IV. PICK-UP/FEEDING
SYSTEM
A. Outline
The NP6085 uses center reference, in which
copy paper is moved through the center of the
pick-up/feeding path for stable pick-up/feeding
operation.
Pick-up operation may be upper/lower front
tray pick-up, paper deck pick-up, and multifeeder
pick-up or re-pick up, used when making two-
sided/overlay copies.
In addition to the feeding path used for one-
sided copies, the NP6085 uses a separate feed-
ing path for two-sided/overlay copies (No. 2 feed-
ing assembly, duplexing unit) formed by the No. 1
paper deflecting plate.
When making one-sided copies, copy paper
picked up from the upper/lower front tray, paper
deck, or multifeeder is controlled by the registra-
tion roller so that the leading edge of the image on
the photosensitive drum matches with the leading
edge of the copy paper; the paper is then sent to
the copy tray through the transfer, separation,
feeding, fixing, and buffer path delivery assem-
blies.
When making two-sided/overlay copies, on the
other hand, copy paper is stacked in the duplex-
ing unit after fixing on the first side. For copying on
the second side, paper is picked up from the
duplexing unit and moved through the path used
for one-sided copies to the copy tray.
