A cheap fix for expensive, over-used scanners. If you have not tried the do-it-yourself repair, you should. It is very simple and it works. Do NOT hire someone to fix this for you. These rollers get used and slick over time and stop feeding properly. They need to have lots of grip to work. Thank you Canon for thinking about the consumer on this one.
These scanner rollers work great. You simply pop out the old rollers, pop these in, and your scanner pulls pages again like it did out of the box. The only reason I can't give this 5 stars is because of the price. These are literally just small pieces of plastic with rubber around them. At most, this should be a $20 item.
