When a piece of paper is inserted into the bypass tray on this printer it pulls it in and holds it for when the print job starts. When it pulls it in there is a rubbing sound it makes. I only recall hearing this noise when it takes it in and holds it. I fairly certain the noise is not made when the print job has begun. I was wondering what could be the cause of this noise? It is also skews the paper as it is pulled in. I've noticed it pull harder on one side and I was wondering if there is a pressure adjustment for it? All of these problems happen in the bypass tray only. Thank you for any help given.
