In re Dembiczak, 175 F.3d 994, 1000-01, 50 USPQ2d 1614, 1617-

We find that Hasegawa teaches in column 2, lines 39
through 41, that Figure 1 shows two image forming units 1a and
1b, each of which is actually a compact printer, and a

image forming units
1a and 1b. From Figure 1's drawing, we find that Hasegawa
does not teach a U-shaped paper path for guiding paper in a
single
U-shaped arc from a paper output port of one of the first
laser printers to a paper feed port of the second laser
printer. From the figure, we find that Hasegawa teaches a S-
shaped paper path which starts from a paper output port of the
first printer shown to the left of roller (15a) to a paper
