In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir.
1988).
A review of the applied prior art confirms that Kimura
relates to a printer that controls the printing parameters once
the overhead projection mode is selected (col. 1, lines 44-49).
However, as acknowledged by the Examiner, a user has to select
the overhead projector (OHP) mode selection key 18 in order to
adjust the transfer voltage (col. 3, lines 47-48). Although
Kimura teaches that the type of the recording media may be
detected automatically (col. 4, lines 31-38), the claimed sensor
for detecting the path through which a sheet of recording medium
fed from the manual paper feed tray passes is absent from the
reference.
Kono, on the other hand, discloses a paper-stuck detection
means in an image forming device (translation, section 0008) but
provides no further detail of a signal indicating which path the
paper is passing through or whether the detection results in
changing the transfer voltage. We also find that Lee, in figure
2, merely depicts a print engine controlling circuit and does not
teach or suggest the use of any sensors for detecting the passage
of a sheet of recording medium from the manual paper feed tray.
