That method works okay in a copy machine that moves the original across a
fixed scan head.  It does not always work very well in the more common
copier that moves the scanner bar or mirror beneath the stationary original.
In the latter case, there are optical errors that exist at the edges that
make it difficult or impossible to line up multiple scans, and this is most
apparent in very detailed schematic diagrams.

It is far better to take long foldout pages of a manual to a commercial
graphics house, where the entire sheet is scanned in one pass into a PDF
file.  My local graphics house charges me only 17 cents per square foot for
scanning, and can handle pages that are up to five feet wide and more than
100 feet long.  I'm not exaggerating- some electrical diagrams for an
airplane are intended to be put on a wall, so that an engineer can follow
each wire from beginning to end.  Once a manual has been scanned so that
each page is one PDF document, the Adobe "snapshot tool" can be used to
select portions or details to print on standard-size paper.  Of course, the
great value of full-page scanning is that the long pages can be printed in
their original sizes by the same graphics shop (and some Kinko's) that have
a roll-feed document printer.
