Rm1-2316 Schematic May 2026

is the primary power supply board assembly used in several popular HP LaserJet monochrome printers, most notably the HP LaserJet 1020, 1022, 1018 Canon LBP2900b Technical Overview

• Components: A ferrite bead (FB1) and a large tantalum capacitor (C6 ~ 10uF).
• Purpose: Prevents RF from leaking back onto the power supply line.

: It acts as the gatekeeper of energy. It steps down high-voltage AC to stable lower voltages (typically 3.3V, 5V, and 24V) to power the logic board, the laser scanner assembly, and the mechanical motors. The Fuser Control Rm1-2316 Schematic

Testing Voltages: Using the pinout diagrams found in the HP LaserJet 1020 Service Manual, the technician checks for 24V (for the motor and fuser) and 3.3V/5V (for the logic board). is the primary power supply board assembly used
