Was wondering if anyone had any ideas about this?
I am getting strange 'banding' or stripes in the black areas of my prints?
This is on my less-then-a-year old Epson 9890, using OEM inks, printing on Epson Hot Press, is happening on both the Bright and Natural versions of the paper.
I put the word 'banding' in inverted commas, because I'm not sure if that is the correct technical term for the problem? In my experience, banding, as caused by a clogged or defected nozzle, is a thin straight line, parallel to print head direction, running across the print. This issue is wider, softer, faint repeated stripe that seems to occur near the edge of the print. The stripes do run horizontal, in the direction of the print head but seem to occur in areas or groups, don't run across the whole print, if that makes sense.
I am attached pictures below which will hopefully better illustrate the problem.
Seem to occur on the edge of the print furthest away from print head 'parking station' (i.e. end furthest away from pump cap assembly). Is it possible problem is related to air pressure in the ink deliver system? That as the print head moves to the end of its pass, the ink pressure drops?
Or is it possibly feed related?
Any comments or suggestions would be gratefully received
Many thanks
