      How about black developer unit ?
      Panic stop the machine and make a inspection of images on all drums

              Do you use original toner?

                  do a deep cleanning of the inside of the machine, change all filters, do maxsetup procedure.
                  Do you know the age of the developer material from your developer units ?
                  Wc 76xx machine are the old ones.

                      Bet your toner has rocks in it.

                              Generally if you are using generic toner, that will cause 99% of your image issues. If you are paying less than half of original price of toner and it is not from a techs trunk, then it is not worth it. Lets do quick simple math, you bought toner and saved $100, now you have poor print quality, ruined prints. You have taken time out of your day to post on here, swap developer units and have same issue. Turns out it was your toner and now have to contact vendor and try to get it replaced. All in all lets just say you lost 100 bad copies, spent 2 hours swapping developers, spent 2 hours writing, checking Copytechnet.com and have a few gray hairs. I would think that is not worth $100 in savings for me. Eventually it will ruin your developer completely and that will have to be replaced as well. These are rated for 400k and I have personally gotten 600k by keeping clean and using OEM toner. Sure more expensive but peace of mind and consistent quality is what I strive for. May look good to me but look like crap to recipient. Beauty is in the eye of the beholder.
                              Think about your time and lost income when deciding to use generics to make money. Your own personal printer by all means use generic.

                              Hope this helps
