Sir/Mam, have you replaced the yellow image unit ? Not the yellow toner cartridge. There two seperate units. Also there are on each image unit blue/white nubs that you can pull out and push back in to clean interal image unit parts do that you do not have to pull the image units out just ensure that when done cleaning they are pushed all the way back in. Once the image units are not toner cartridge and there are four of them located below each toner cartridge .

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

you will need to go through the complete setup procedure again by the book, if that does not work you will need to replace the black iu610. please follow it step by step, even setting the time and such along with printing out all of the management lists, for some reason this machine is very specific on setup.

That sounds like a white balance issue to me. Do you use manual white balance setting or auto white balance?

try to repl. transfer belt then clean all contact of transfer belt

The easiet way is to open all trays and load the bypass and tell the machine you loading 8.5 x 11 on bypass.

You can also set it on any tray within the menu of the copier under paper > then select tray > then change paper tray settings. Usually it is set to auto. but you can change bypass to what ever size you want with respect to the spec of the machine.

with the document open, go to print, then printer set-up and text color, set to black, background color set to none. Should help
