The NuArc FT26V2UP Flip‑Top Platemaker is a heavy‑duty lithographic exposure unit that uses a multi‑spectrum metal halide lamp and single‑channel integrator to deliver consistent UV doses for printing plates, color proofs, and daylight films. Common failure points in this class of equipment include lamp burnout or poor filament contact, power supply arcing or capacitor degradation, controller board overheating, and mechanical wear on the flip‑top carriage or exposure table. Initial diagnostics should verify that the unit receives clean 115 V/60 Hz input, check lamp voltage and current against spec, inspect the integrator and control board for burnt components or loose connections, and review any error codes displayed on the panel.[oss-gpt-20b]
