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.
If the paper is not being pulled into the scanner from the document feeder then it is probably dirty rollers. You can use rubbing alcohol on a lint free cloth to clean the rollers. You do not need to lubricate the rollers.
