Below you will find the Xerox ColorQube 8570, 8870, 8580, 8880, 8700, 8900 Drum Wiper Blade Removal Procedure. I’ve been seeing more and more problems with these units as they age. In some cases the wiper blade comes detached and will cause smudging. Other times, so much build up gets on the blade that the drum doesn’t get proper lubrication and while cause poor ink transfer and ghosting down the page.
The two things that I really watch when doing this repair are to make sure that when I remove and install the maintenance unit that I don’t touch the surface of the drum with anything, especially the metal of the unit, and installing the wire back through the frame hole can be annoying. The main thing is to have patience and take your time. The instructions can be overwhelming but if you look at the pictures in the middle of the article that might make it less confusing and easier to handle.
