Pink toner hue on all but black print

[WIZARDofJOZ]

I have a Pro C5100s. All of the color sheets have a magenta toner on them. The black by itself does not.

I will add pictures so you can see.
is it is a Transfer belt issue or what?

It is a problem with either the Magenta PCDU or the HVPS for the Magenta charge roller. The magenta on the ends of the transfer roller is because the entire width of the magenta drum is getting toner applied to it.

I did put a new charge roller, Wax bar and blade. Vacuumed everything out really well. I am not sure why it would go from a slight hue to this much toner

Try replacing the magenta drum potential sensor.

wouldn.t that throw a code....no code on machine

[TonerMunkeh]

Not necessarily, I'd try a drum first.

Try replacing the magenta drum potential sensor.

could try swapping the sensor for a different colour to see if the issue follows the sensor if you dont have one and want to confirm before ordering one

Replaced entire drum Unit (PCDU) After printing about 50 pages there micro tiny random dots of magenta over the whole the sheet. the sheet looks slightly tinted

Could it be the Transfer Belt cleaning unit??

[JonManchester]

The cleaning unit wouldn't just have magenta allowed on pages, you would have multiple colors and issues. It could be the itb transfer roller for the magenta unit. It's definitely related to the magenta PCDU or itb transfer.
