Review on 📃 DR-3010C Document Scanner Exchange Roller Kit by Canon, Black - 3335B001 by Sean Perry

These are the only moving parts so they are the only parts that will wear out in the scanner. I can't believe the difference replacing casters makes. And be sure to replace the caps even if they don't look worn. (they are included) Your lids will shed with age and pull back and forth causing stains and misfeeds. A great way to spend some money to get "like new" results.
