Using a new ribbon and the unit running, check the position of the ribbon on the rear rollers of
the right and left ribbon guide arms as the ribbon moves towards the right and then as it moves
towards the left. See that the ribbon is tracking properly in both directions; if not, refine the
adjustment. Tighten the right and left adjusting bracket mounting screws and eccentric clamp screws.
To Adjust
If the new ribbon does not track per this requirement, loosen the right and left adjusting bracket
mounting screws and eccentric clamp screws. If the ribbon is tracking high on the right hand roller,
rotate the high point on the eccentric toward the left. If it is tracking low, move the high point on
the eccentric towards the right. If the ribbon is tracking high on the left hand roller, rotate the high
point on the eccentric towards the right. If it is tracking low, move the high point on the eccentric
towards the left.
