pertinent part the following limitations: “determining whether a
black data reception stop mode has been activated while scanning
said image data on said document; printing the image data scanned
during said scanning step when said black data reception stop
mode has not been activated.”
The specification describes the black data reception stop
mode as follows.
Following step 206 of storing received or copied
image data in memory unit 20, central processing
unit 10 detects, step 207, whether a sequential
predetermined number of lines, i.e., a whole page or
half a page of stored image data, is black data. Here,
black data is [sic] intended to be detected by page
unit (e.g., one page), but it can be detected by line
unit (e.g., 3 lines, 5 lines, or more). When central
processing unit 10 determines that the number of lines
of black data stored in memory unit 20 is not more than
the predetermined number of lines, the image data is
read from memory unit 20 and provided to printer 70 to
be printed, step 209, in a normal printing operation.
On the other hand, when central processing unit 10
determines in step 207 that the number of lines of
black data stored in memory unit 20 is more than the
predetermined number of lines, central processing unit
10 proceeds to step 208. In step 208, central
processing unit 10 controls printer 70 to print image
data corresponding to a quarter of one page of stored
image data as black data and the rest as white data.
(Spec. at 8-9.) Reading claims 15, 17, 19, and 20 in light of
the specification, the limitations require inter alia
