Service Checks

Note: All service checks which involve measuring voltages of the circuit boards (except the controller board) must be performed with the engine/LVPS to controller board cable disconnected and the printer positioned on its left side. This provides the servicer access to the various circuit boards underneath the printer while supplying necessary power to the rest of the printer.
