Wow...The guy I hired for $150 just unscrewed the side of the printer and then managed to get the belt in without removing anything from top. He was so fast he did it in about 30minutes. Best $150 I spent, and I am now in the position to do it again!!! That is only 4 or5 years my belt lasted. I think there is a makers that guarantees it for more, non oem. Good video overall, just wish you didnt have to go through all that..BUT, you are now intimately familiar with a lot of the workings.
