Random drops of toner - Help Please - Pics attached

[WIZARDofJOZ]

I have pictures showing the black spots of random size and placement only on the left (Front of copier) side of the sheets about 3" in
I also have the pic showing the toner build up on the front side ONLY of the transfer roller. I have changed out the entire black drum unit and charge roller and wax bar.
it seems to be dropping from somewhere on to the sheet as it passes???

Any thoughts? 1000011873.jpg 1000011874.jpg

It could be the development unit leaking, dirty ITB or ITB cleaning unit. Any of which could be caused by not using Genuine Ricoh toner.

All I use is Genuine Ricoh Toner. I don't trust the compatible stuff. I also have really small micro spots of magenta on over the whole sheet. Can't see them without a loupe
Transfer Cleaning unit?

Could be or the ITB assembly
Oh by the way. what is the model? Some problems can be model specific.

Ricoh Pro C5100s

This looks like waste toner. I'd start by removing & rebuilding the transfer cleaning unit.

I agree, it should be the ITB cleaning group
