Specification Highlights and Reference Data

This resource includes exact voltage specifications, detailing +5 VDC (4.75–5.25 VDC), +15 VDC (14.25–15.75 VDC), and +26 VDC (24.7–27.3 VDC) rail requirements. It supplies fuser thermal control data, logging normal operating temperatures alongside fault thresholds at 420°F (215°C). You will also find comprehensive electrical connector pinout tables for the Control PWB and LVPS/Driver PWB assemblies. These schematics ensure accurate diagnostic testing of the print engine, scanner module, paper path, and electrical systems. Navigating high-voltage circuits and heated fuser assemblies requires strict adherence to factory protocols. Always reference these OEM specifications to ensure safe handling during any hands-on hardware repair.
