Digital BW, The Print

aa,

You might try the soaked paper towel routine as this is probably something
that should be done periodically to keep the bottom of the heads clean. You
could also put in some Epson cartridges and run 2 or 3 purge pares. The
Epson carts are great for cleaning.

What setting are you using in the Piezo driver? If it is set to Best, try a
print with it set to Better and see how that looks. Also the vertical
banding and/or "window screen" pattern where the Piezo dither show through
can sometimes be improved by adjusting the print size slightly, without
resampling, so that it falls close to an odd number dpi rather than even or
a multiple of 10.

Martin -- Your suggestion about avoiding round-number DPI settings 
has made a substantial improvement. Thanks SO much!

Why should you not use round numbers for DPI? and what numbers caused
the improvement?
