Typically the pinch rollers need cleaning, dirt, ink, and possible paper dust will collect on the rollers and stick to your paper, try cleaning all the rollers first.

Thanks for an update, I did try the suggestion you provided still i see paper jam. What else can be the issue? What about the roller in back (i.e. kind of Red color)

Please clean everything that the paper touches, this is only preventive maintenance to keep your machine clean and attempt to prevent future problems, you might have a bad bearing or bushing or the inner area of a roller is worn allowing it to no roll straight and true like when it was new, see if anything is loose feeling.
