Phaser 6280 -- very faded and blotchy black output

[Tutor5]

If I print a solid page of magenta: perfect.  Solid page of yellow: perfect.  Solid page of blue:  perfect.

But a solid page of black:  extremely faded, and blotches all over the margins.

I once tried a non-Xerox cartridge, but since then I've tried several genuine Xerox black cartridges (all the color cartridges are genuine as well).  Still no improvement.

Thanks.

Hi Tutor5,

Thank you for using the Support Forum. Please take a look at this solution for faded prints of one color. If this does not help please consider contacting your support centre for further assistance.

Thanks for the idea, but as mentioned I've tried several genuine Xerox black toner cartridges, and the problem persists.  Clearly not a cartridge problem.
