Digital BW, The Print

Yes I stand corrected. The rollers don't swing upward, just the pizza
wheels when you wedge up the plate in the manner I described. I now
remember I was worrying about both wheel and roller marks at the time.

When I cleaned my rollers using the method Epson describes with water,
nothing big happened either. But my rollers really weren't dirty, as I
said my glasses were creating the illusion of a problem<g>. Doh...

There was one other trick I now remember though that may really work
for your Ilford paper. Slow the print transport down. In my imageprint
RIP the only way I can do this is choose 2880 instead of 1440 for dpi.
But the Epson driver (Windows version at least) allows you to insert a
time delay of a number of seconds (I think maybe 1 to 15, it was some
time ago I looked) after each head pass. I never saw this option for
1160 or 1280 but just my 2200 Epson RIP. I'm sure it's buried deep
under some "advanced" button somewhere in the print dialouge.

You might try that although it would certainly take forever to spit
out a print. But it would give the ink time to dry and roller marks
would be less of an issue.
