Hmm, interesting. My HP5300C also requires calibration, however it actually
contains a standard white surface within the scanner itself. The calibration
is automatic before each scan. Hence the tables are not available to the
frontend anyway.

Oops, upon rereading maybe you mean the gamma correction rather than
the min/max values? That the curves may be different for each colour? To do
that SANE would need to provide an image to print which you can scan and
calibrate against. Anyone have such an image?

It does seem to do quite good actually.
