Xerox 7700 intermittant banding on a diagonal black only

I have a issue with black printing. The black toner is intermitant on a page. The missing or very light areas are banding on a page and run at a diagnal at about 1 inch a part. If I print the solid color test pages, all colors are ok except black. I replaced the black toner, no help. I swaped the print cartagre with another color howerer the problem stayed with the black color.

You most likely have a bad black developer housing.
You can try removing the waste bottle and using that bla\ck stick inside the cover to clean the laser ****.
But it sounds like the developer housing has failed.

Erratic black fusing


I'm not real sure about how the software separates the colors, but I believe there's a way to choose a color as all colors combined to make black, or simple black. 

I'm not sure if I'm making any sense, but if the printer is using all the colors to layer up and make black, then it would be a pretty thick coating and that might cause it to flake off.

There are large black bands on all my pages when


This is generally an issue with the drum rather thatn the toner cartridge. To fix such an issue, generally one must pull out the toner and the drum, then clean the toner powder from both the drum and the inside of the printer. The lines are usually caused by a buildup of excess toner powder caught within the machine.

Xerox Phaser 7700 printing Black line across bottom of every page


The line could be caused by contamination on the black laser lens. Try using the cleaning wand located in the front door to clean the lens. You will need to remove the waste toner container to access the wand slots. If that does not solve the problem, the black developer housing may need to be replaced.

Xerox XC1020 White Bands running across copied page 4" apart


The metering blades in those cartridges go bad and do not allow the ink to get to the page. Look at the front of the toner cartridge, is should be a solid consistent black all the way across, if its streaky, not consistent all the way across replace the toner.
The other problem could be a dirty laser. If replacing the toner doesnt work let me know, I will tell you how to remove and clean the laser.

Phaser 7700 steaks on Magenta, sometimes yellow.


Each color has its own laser. Use the cleaning wand in the front door to clean the lens covers for each color. You will need to remove the waste toner cartridge in front of the the slots to do this. If that does not cure the problem, you will need to replace the developer housings for the colors that are streaking.
