Our large format printer leaks black ink.  It only leaks when the print heads are in the rest position, to the far right.  I can't get it to leak if I turn the power off and manually move the print heads to the center, so I don't think it's a print head leak or tube leak.

Make sure that the service station does not have any foreign material on the head caps that are preventing proper parking. Even a small piece of paper could cause wicking that will draw ink out of the head.
