The LT Series consists of four models, and is designed to meet virtually all of your validating needs. Standard features include: automatic registration; motor-driven ribbon shift for smooth, quiet operation; easy ribbon changing; registration position adjustment; and registration impact pressure control. Available options include a digital display, a manual registration button; allowing automatic or manual action, as well as repeat and advance numbering. All units carry a full one-year factory warranty.
