I would greatly appreciate any suggestions to fix this problem: I
have the Scandall 2001 software by [fujitsu.com?], a Compaq pc, and a
Brother MFC 6800 scanner/printer: With the same setup I used to be
able to scan lots of paper pages in one go, except of course if some
page got stuck or awkward in the document feeder.

But now it's as if something has changed: now the maximum number of
paper pages that scan in one go into the document feeder is usually 7,
or 2, which is too few. After fairly thorough review there is no
relevant setting, tip, workaround, etc. in the Scandall 2001 Help
Contents or Index. Thanks in advance.

Background:
The Brother MFC 6800 scanner/printer has its drivers up to date (for
the Windows XP Professional that is on the pc), but i somehow infer
that the small-maximum scanning problem is controlled not by the
scanner but by the pc's "Scandall 2001" software.
