grey cast is left on the paper.

Most likely, there is no "grey cast"--the idea of a "grey cast" in a B&W pho
to
makes little sense. What you're seeing is the fact that the contrast is too
low.

The right way to fix this is to use your scanner software's advanced control
s
to set the hilight and shadow point appropriately. If you don't want to re-s
can
the image, use the Curves command to increase the contrast.

What about just using the "brightness/contrast" option, or does
adjusting the curves give a better result?

The "brightness/contrast" command should not be used on any image you actual
ly
care about. Photoshop's "brightness/contrast" and "color balance" commands a
re
only there for novices who don't want to take the time to learn Levels or
Curves and don't care about quality; they are "linear" commands, which means
they degrade the quality of the image by removing detail from the hilights
and/or shadows of the image.

Curves can do absolutely, positively everything that Brightness/Contrast and
Color Balance can do, but Curves is a "nonlinear" command; it does not degra
de
image quality by clipping image detail.

In retrospect I don't use brightness/contrast on images I care about, I
use it to better define a black and white scanned line drawing for
digitising.

For an image that's intended to be bilevel (all black or all white), there i
s
no hilight or shadow detail, so the fact that the Brightness/Contrast comman
d
clips hilight and shadow detail is irrelevant. :)
