The two rollers (feed and retard roller) installed in your scanner are consumable parts. The feed and retard rollers will wear with scanning. If the feed and/or retard roller are worn, documents may not feed correctly resulting in either paper jams or double feeding of the documents. When more than 200,000 pages have been feed (total number of pages feed by the scanner), a message prompting you to replace the rollers is displayed on the computer screen.
Note: The message on the computer screen will always appear on the computer monitor whenever the PC is powered on, until you reset the roller count.
