Do you have an optional tray? If not, there's isn't a kit. But the only roller that really needs some attention now & then is the MPF feed roller. It has a clip on each side that can be released, the side holders(5) slide away, and the roller(6) slides to one side then rotates 180-degrees for removal. Unless you have real small hands and arms, it's tough to reach. Always use water and a mild soap solution to clean the rubber surface, never alcohol.
