Post a sample.

Unfortunately I cant post the Sample, it is a Confidential document. But it is about 1 inch wide and runs the width of the page.

Just because the line is black, its not necessarily the black toner causing the problem, could any of the other toners. Yellow/magenta generally the culprits.
