Getting started 1
INTRODUCTION AND SAFE OPERATION The LS7 printer was designed specifically to make cable, patch panel, faceplate and facility marking effortless. This palm-sized printer combines high quality thermal transfer print, fas t loading tape cassettes and industrial label materials to eliminate concerns about labels falling off. This manual will guide you step by step through the set-up, operation, and troubleshooting of the LS7 Printer.
