Is the outline of the "B" a different color other than black. If black was clogged the outline should not print.
On the WF1100 In your nozzle check there will be 2 black pattern "blocks", one for each black print head, the CMY is the 3rd pattern block. If one head has trouble you can easily see it.I'm pretty certain it is pulling from a black tank. There are two black tanks, so I'm supposing that just one is having issues?
You changed the printhead or the black cart for the CIS? Changing a printhead is big ordeal.Thanks for the helpful info! Cobra sent me a new print head which totally fixed my problem. I just have to always turn off the printer and use it often.
That's what I thought. Those substitute for the regular carts.I'm not sure if I'm using the right term- the plastic tanks that go inside the printer, that is what i changed. It was hard, the tubes did not come out easily and the plastic brackets holding them on snapped into pieces. Bring on the miracle of super glue.
