EPSON - Epson Perfection4990Photo Diagram
Complete parts identification and assembly diagrams for the EPSON GT-X800 / Perfection 4990 Photo scanner. Organized as four detailed photo sections that map every component and mechanical subsystem of the unit. The first section shows all accessories and power/interface connections, with separate diagrams for 100V and 220V variants including power supply connectors and cable assemblies. Sections two and three break down the external casing, internal frame, optical pathway, and motor drive train. The final section isolates the core mechanical elements—scanning head, stepping motors, drive belts, and carriage guide rails. Each part carries a reference number for quick cross-referencing against the parts list. Indispensable for service technicians and authorized repair centers performing component identification, parts replacement, and mechanical troubleshooting on this flatbed photo scanner.
