Ernst,

Thanks for responding.

I've done the usual alignment that is accessible via the driver.  I've also
checked the B & C Head Slant/Height adjustments through the 7500's display
panel.

Are there any other adjustments that would affect microbanding?

Is there more to "rheology" than viscosity?  (I'm not a chemist.)

One of my theories in purchasing a 7500 was that, being made for pigments,
it might be better for the pigmented inks I use than the 7000.  For example,
it has been my impression that the new "high-load" pigmented inks are close
to the limit that standard desktop printers can handle.  Also, I think, that
the pigmented printers might have some firmware (?) routines for cleaning
that may be useful.

When doing curves for the 7000 and 9000, what I noticed with them is that
the Epson driver gave a lower dmax than the desktop printers.  The 7500, on
the other hand, is said to pump out a lot of ink.  That may also be the
voltage difference you mentioned.  The dmax I'm getting with the
"Watercolor" paper setting is higher than my 1160.  So, it looks like the
7500 does have a better dmax than the 7000 with the Epson driver.

If I do try the 7000 driver, is that anything more to it than just
downloading/installing it?
