I attached two pics, one is multiple top edges stacked. Second is photo of drums where one can see a clear line of dumped toner across the entire tray. I am being sent out to replace the cleaning blade on the ITB Cleaning Unit, but I am arguing there is something else happening causing the toner to accumulate. Got concerned when a waste toner collection bin was ordered because they "fill up so quickly."
Thanks for any help.
