Application No. 09/670,146
OPINION
In reaching our decision in this appeal, we have given careful consideration to
the appellant's specification and claims, to the applied prior art references, and to the
respective positions articulated by the appellant and the examiner. As a consequence
of our review, we make the determinations which follow.
We turn first the rejection of claims 1 and 4 under 35 U.S.C. § 103 as being
unpatentable over Wen in view of Sevier.
The present invention relates to a method of controlling print nozzles of a full-line
printing head in an inkjet printer for printing digital photographic images. The method
seeks to prevent any image printing from extending beyond the edge of the recording
medium. In connection with this goal the specification teaches that when printing
extends over the sides of the recording medium, ink gets onto the transport substrate
and ink consequently becomes smeared onto the backside of the next paper proof so
that the printout is unusable (specification at page 1). The specification further states
that such ink can eventually result in paper transport malfunctions in the printer. The
specification of appellant’s invention discloses an electronic control system that
deactivates any print nozzle when a line (of digital image) is sensed by a CCD line
sensor that is wider than the cut sheet of the recording medium (specification page 5) .
