Hey fellow Techs I looked through Threads for this issue to no avail.
Yellow toner build up on rear side of PCU causing a parotic yellow image on rear side of prints.
There is a yellow toner build up on top of PCU Cleaning blade toward rear only.
New Drum, Blade, and Transfer Cleaning Unit. I find yellow toner on rear side of secondary transfer roller as well.
This issue is yellow only.
OEM Toner used. 250k on box.
I hope someone has had this problem as I really don't want to keep shooting in the dark.
Thanks for your help.
