Digital BW, The Print

Thanks, Tyler.  I think you've nailed it.  My "left edge" is indeed the trailing edge of the print, relative to the printer.  Looking closely, I also see a narrower darker band on the leading edge.

I found nothing of any help in the R1800 docs. Luckily, I still have the installation for my old 1280 (also a 13: carriage) on my machine. The 1280 docs talk about the "minimum" margin checkbox decreasing the minimum margin that the Epson driver allows from 14mm to 3mm, with the warning that your print quality may decline or it might smear.  

When I looked closely at my problem print in good light, the banding on the trailing edge of the R1800 print is just a smidge over 1/2 inch from the paper edge.  So I'll just use a minimum of a half-inch margin from now on.  Which jogs my memory--I think I figured this out a few years ago, but had forgotten.  

You might try the half-inch minimum yourself.  If the mechanical design of your R1900 transport is similar to my R1800's, I suspect you'll be fine with that.

It looks great except for one thing.  On the left side of the print (which comes out of the printer last), there is a vertical band, about 3/8 inch wide, that is slightly darker than the adjoining area. It may actually be two bands, the outer one darker than the inner.

My right and left margin for this print were about .28 inch.  I don't have this problem with a color version of the same file on my R200 printer using the Epson driver.
