Deskjet 9800

My Deskjet 9800 seems to be dragging the ink vertically through a page
from top to bottom. It looks to be only one or two pixels wide but it
sure detracts from the desired product. Any ideas?

I have tried the clean cartridges bit and the other items in the HP
Toolbox with no luck. Neither can I find anything physical that is
dragging on the page to make such a mark.

TIA for any help you can provide.

I have seen this happen when people use recycled paper. Small fibers are
left in the paper path and can be really hard to see. I would suggest
going through the paper path near where the ink is deposited to the end
of the paper path with a good magnifier. You should pay particular
attention to the bottom of the ink cartridge. I suspect you'll find
small paper fibers that are smearing the ink.
