Digital BW, The Print

The moral of this issue is that I should have bought new.  I saved 
$300 buying used but spent $100 in shipping and so far over $200 on 
repairs to this supposedly "almost new" printer including new heads.

At any rate, special thanks to Paul Roark for helping me out so far!

Here is the deal. I have tried the printer on both an XP system and a 
W98 system with the MIS-VM Sepia inkset.  Printing on EAM.  Images 
are those that I have printed with success on my 1280 with the Cone 
driver/inks.

I have used Paul's curves and workflow.  When I print via the Epson 
driver (most current driver downloaded from Epson)I get very distinct 
microbanding.  Colors look good though.  If I take the same image, 
convert to grayscale and print via the Cone driver, there is no 
microbanding at all - very crisp (of course the color is really 
ugly!).  

I am really confused now because I have always had the impression 
that if you were going to see banding it would be with the Cone 
driver and not with the Epson driver.

I have checked my settings several times.  Any suggestions?

Thanks,
Dave
