The LaserGraphics LFR Mark III is a high‑resolution digital film recorder that exposes 4×5, 120/220 and 35 mm positive or negative film using an internal LED array and precision motorized film transport. Common failure points in this class of equipment include lamp burnout, drive motor wear on the film carriage, misalignment of the exposure optics, and failure of the control board’s power supply rails. For a first‑pass check, verify that the unit receives correct 120 V/60 Hz input and that all fuses and circuit breakers are intact; inspect the LED lamp for visible degradation or burnt filaments; and confirm that the film transport motor runs smoothly without unusual noise or stalling. If these steps are normal, proceed to review any error codes displayed on the control panel and perform a visual inspection of the optical path for dust or mis‑centering.[oss-gpt-20b]
