Digital BW, The Print

I never print in landscape mode, but if I'm not mistaken, your "left" edge would actually be leading or trailing edge as the paper moves through the printer...
So, with my 1900, and QTR, with minimal margins, I get banding errors at the beginning and end of the print. I'm not sure if it's that the transport doesn't have good control of the physical paper advance at the beginning and end, or what.
But, the solution has been to print on a sheet somewhat too big, with large leading and trailing extra paper. I haven't determined exactly how much it takes, but I'd say an inch seems to do.
I suspect you are seeing some similar incarnation of the same problem.

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.
