This replacement plate heater is a critical component used in Mitsubishi, Screen, and Presstek platemaking systems. Commonly found in Eco 1630 series processors, it is designed for safe, submerged operation within photographic chemistry trays. The U1100039-02 heater is stocked and ready to ship for urgent service needs.
A failing heater often triggers the circuit breaker in your platemaker. After installing a new unit, ensure the internal breaker is reset. The activator tray's rear grounding lead plays a vital safety role, allowing the system to safely shut down via ground fault when a heater fails—indicating the need for immediate replacement.
