Is it possible to improve, lubricate or replace the scaner roller
I’ve had the HP Envy 7640 all-in-one printer for a little over a year. I am wondering if there’s any way to lubricate, improve, repair or replace the roller located in the document feeder? I guess I’m asking if this is possible.. Much like you lubricate the roller-shredder on a paper shredder - using either the pre-lubricated paper sheets or the oil itself.. Thank you.
