Digital BW, The Print

http://www.grubba.com/nozzle.jpg

Could someone please look at the linked scan of a nozzle test and see if
you know what is causing this? That stubborn line remains off no matter
what. The printer (a 7000) is theoretically clean and aligned. I'm using
the PiezoBW (or Sundance, or whatever they call it nowadays) inks. I've
been using this for over a year and never had a problem before.

TIA,
