When the rollers start to wear out, document feed errors such as paper jams are more likely to occur. If document feed errors continue to occur even after cleaning the rollers, purchase an Exchange Roller Kit, and replace the rollers (feed roller and retard roller) and their covers (feed roller cover and retard roller cover), and the document holding guide.

• Exchange Roller Kit
  The Exchange Roller Kit is a kit consisting of replacements for the feed roller, retard roller, and document holding guide.
  
  
• Rollers and their covers, and the document holding guide are consumable parts. When the total number of pages scanned with the rollers reaches 100,000 pages, purchase an Exchange Roller Kit and replace the parts.
• When the rollers start to wear out, problems such as paper jams and improper document feeding become more likely to occur. If this happens, replace the rollers regardless of the page count.
• Make sure to reset the roller counter after replacing the rollers.
