Thank you, I found that first video too, but it refers to the pick roller.
The problem on mine is on the feed rollers, the ones in the bottom of the scanner.
Seeing the link you posted, I think they don’t consider feed rollers as consumables, just the pick roller and the Pad assy.
I’m not comfortable in replacing them without instructions, but the alternative would be to buy a new scanner.
Decisions, decisions…
