On a Canon MP 460 printer, the paper will not feed in straight causing constant paper jams.

If the paper feed roller is dirty, paper is not fed properly because the paper feed roller slips. Cleaning the paper feed roller could resolve the paper feeding problem. Please follow the instructions below to clean the Paper Feed Rollers directly from the unit.Caution: Since the cleaning process wears down the paper feed roller, perform this procedure only when necessary and no more than three (3) times.

1. Ensure that the printer is powered on and remove any paper from the Auto Sheet Feeder (ASF).
