Elizabeth,
You do point out some significant scanning areas that need to be improved.
Many of the errors you outlined are caused by either high or low brightness
settings. If the submitters' OCR program provides a gray-scale setting, it
should be used as much as possible--especially when It comes to K1K 8.01.
Most of these problems are removed by that setting. The optimized settings
should be tried and compared with gray-scale with 400 DPI. In most
instances, you will find that the gray-scale setting wins. My second
suggestion would be to ensure that the scanner scan at least 10 random
pages of the book in question and check the quality. Most of the problems
that are likely to occur will be displayed in these pages. Setting
adjustments can be made if there are predominant problems of a certain kind.
Please see Guido's messages on this point as well. He has a wealth of
best-practice information that can elp as well.

I almost totally do validating rather than scanning. perhaps what I ask
below is asking a lot. I am, however, concerned about the following
patterns which occur a lot. Perhaps someone can talk about how to set a
scanner so they appear less often. The reason I keep harping on folks
getting better scanning software (that is the new upgrades) is that some of
these scanning settings can then be set by the scanning software
illiminating these patterns.
rn for m as in bam for bar, cornputer for computer, cornmande for command,
n or bum for burn
m for rn resulting in comer for corner
space hypens in the middle of words particularly names such as Eliz -abeth
or Eliz -abeth
large chunks of garbage text where diagrams should be which sometimes
causes the braillenote to crash during validating
I for 1 resulting in i8i5 for 1815
1 for I resulting in 1 am instead of I am
A validator get gets rid of these using find and replace judiciously of
course. It still takes a lot longer to do this than it does to get the
scan right in the first place.
Finally remember those who scan get about three fifty worth of credit per
scan. Validators get fifty cents per validation. Not a big point but
certainly one which demonstrates the dedication of validators.
Even use of rank spelling could mean some of these errors can be fixed
before the book is uploaded to the step 1 page. If I can use rank spelling
to fix cornmand into command so can a volunteer scanning a book.
