8000i many toner powder inside

Hi, Kyocera has a new UPGRADE KIT, it addresses several issues but it has several seals in it to prevent toner blowout. It is for the 6500/6550/7500/8000 machines. There is a video on how to install it at the Kyocera site. Hope that helps.

I'm a Utax dealer so I dont have access to that video does it say what the problems are why do they do it?
