Now it is over toning on the black, even when I choose a single color. Example; I ran cyan only and still
have the black back ground. The charge roller for the black drum is not cleaning off and is coated with
toner as is the drum.
I did a toner refresh on the black. Now it is trying to add toner to the black unit and it either is not
or does not know it has. I don't have the option of trying a different black developer unit or drum
yet. I am still in the scratching my head phase and reading the theroy guide for a clue.
First I will have to get know good drum and developer units.
This customer bought these at an auction and there was not any service documentation.
Thanks for your input
