2. Paper finish (photocopy or typewriter bond preferred). If the finish of the paper stock is smooth, then the paper may slip or be skewed due to poor or uneven feed roller adhesion.
3. Age and use of the LaserWriter. The older a LaserWriter is, and the more heavily it has been used, then the higher the chances are for poorer print registration. This is due to the wearing of the paper feed roller and accumulation of paper dust. These factors cause the paper to slip slightly during paper pickup and feed. Regular cleaning of the paper pickup and feed rollers should eliminate some of the registration problems.
