Digital BW, The Print

well, i tried printing the image with high speed off and the banding is
almost completely gone. it's gone enough to be not noticeable unless you
knew it was there to look for. so that solved the issue but any ideas what
the base problem would be that would cause that when printing at high speed?

Frank,

I did look at your image and I have ever encountered anything like that.
This was printed from a patch generated in PS so there are no issues of
scanning problems, etc. Does it occur if you print the same patch with all
the inks?

The only think that comes to mind is some mechanical problem that is causing
the side to side head speed to vary.

Does the problem change if you turn "High Speed" on or off in the driver
settings?
