Abstract
An image forming device is provided that includes a fuser section having a carbon nanotube fuser roll; a pressure roll that interacts with the fuser roll to create a nip; an external heat roll that contacts the fuser roll and transfers heat to the fuser roll; and a cleaning system for cleaning contamination deposits from the external heat roll. The cleaning system has a scraper blade configured to contact a surface of the external heat roll such that the deposits are scraped from the surface of the external heat roll; a catch tray positioned relative to the scraper blade such that the deposits scraped from the surface of the external heat roll by the scraper blade are collected by the catch tray; and a deposit transportation auger located in the catch tray, the auger being configured to transport the deposits from the catch tray to a collection box.
