Rm1-2316 Schematic May 2026

The HP RM1-2316 Go to product viewer dialog for this item. is a 220–240V Low-Voltage Power Supply (LVPS) board assembly, primarily used in the HP LaserJet 1018, 1020, 1020 Plus and compatible Canon models like the LBP2900.

Transformer/Switching Section: Converts high-voltage AC to low-voltage AC. Rm1-2316 Schematic

• Components: An LC low-pass filter (C3, L2, C4) and a DC blocking capacitor (C5).
• Purpose: Matches the output to 50 ohms and attenuates harmonics (2f, 3f) to meet regulatory standards.

1. Power Supply Inputs (+24V DC / +5V DC): These rails power the logic ICs and the gate drivers on the board.
2. Control Signals (ON/OFF): A signal line from the DC controller tells the RM1-2316 when to engage the heating element.
3. Feedback/Status Lines: The board sends status data back to the printer (e.g., "Ready," "Fault," or "Overtemperature").

6. Where to Find the Exact Schematic

1. Look for the host device model: Search [Device Model] service manual (e.g., "IBM 5150 power supply schematic").
2. Search patent databases: Search "Rm1-2316" AND "power supply" on Google Patents.
