Conjunto de sensor de registo PCB para impressoras Brother LT2699001 – placa de sensor de substituição

PCB Assembly Registration Sensor LT2699001 is a replacement sensor board designed for Brother printers. This component performs registration sensing to detect paper position and ensure correct alignment during printing. Intended for service and repair use, the board restores registration functionality by replacing a faulty or worn registration sensor assembly and helps maintain consistent print registration and document feed accuracy.

Advantages

The replacement PCB assembly provides the same form factor and connector layout as the original registration sensor, facilitating direct swap-in installation without modification. It restores reliable detection of paper position to reduce misaligned prints and paper jams related to registration errors. The board is suitable for repeated handling during servicing and is compatible with standard repair procedures used by technicians.

Suitable for

• Repair shops performing maintenance and component replacement on compatible Brother printer models
• Technicians troubleshooting registration errors and misalignment issues
• Service centers restoring printers to factory registration performance
• Preventive maintenance where sensor replacement is required to maintain print quality

Key specifications

• Function: registration (paper position) sensing for print alignment
• Form factor: printed circuit board assembly designed to match original sensor dimensions
• Connectors: PCB-mounted connector(s) compatible with original printer harness (matching pinout and mounting points)
• Mounting: screw or snap-fit mounting points corresponding to the factory sensor location
• Durability: designed for service use and repeated installation during maintenance

How to use

Before installation, power off the printer and disconnect it from mains power. Open the service access panels to reach the registration sensor location and document the connector orientation and any mounting screws. Remove the defective sensor board by disconnecting the harness and unscrewing or unclipping the assembly. Install the replacement PCB assembly by aligning it to the factory mounting points, securing it with the original screws or clips, and reconnecting the harness in the correct orientation. Close access panels and restore power, then run a printer alignment or service test procedure to verify correct registration detection and paper alignment.

Recommendations

Use only when compatible with the specific Brother model listed in service documentation. Handle the PCB assembly by its edges, avoid contact with exposed circuitry, and use anti-static precautions during installation. Verify connector seating and run printer diagnostics after replacement to confirm correct operation.
