I've seen a couple of Task Alfa color machines (4550ci, 5550ci) where the ITB is leaving grey or colored smudges on the back of copies, especially on the first 2" there will be a yellowish grey bar. It goes away of course if you replace the ITB, but have any of you had luck with vacuuming the ITB cleaning section out? I have a feeling that at 400 - 500K it would be a waste of time. Any thoughts?
Thnx
