TRACKING ADJUSTMENT
Check tracking by moving a piece of paper in and out of the electric eye. At this time, the
tension roller should move from side to side. If the tension roller does not move, the electric
eye and solenoid valve must be checked.
If belt runs to one side and the tracking cylinder is extended out full travel, loosen jam nut on
cylinder and move the cylinder push cap out, or move the spring tension in.
If belt runs to side and the cylinder shaft is in, add spring tension by loosening jam nut, then
turn the spring tension screw in.
