OK, I've got a LJ4600 that prints terrific as long as there is color on the page.
If the user prints straight black text with no color, from the center of the page going to
the right margin the black text fades until it can't be seen when it reaches the right margin.
The center to the left margin is good.
Once you put anything of color on the page (a red "A", a cyan "dot", a colored logo) the black text
is perfect all over the page.
I ran "disable cartridge check" using only the black cartridge(which is a brand new out of the box HP black).
I had the user print the black only document. The o/p is good. I then put each cartridge in one at a time with the
user printing the same document with each insertion. All good o/p.
I then exited out of DIAGNOSTIC mode and let the user print the document again....failure.
If they print greyscale all is good. Greyscale only uses the black.
I need some direction and ideas.
