Brother International LB3781-001 110V AC Power Cable

Brother LB3781-001 110V AC Power Cable

Overview

The Brother LB3781-001 is a factory-new 110V AC power cord for North American deployments of Brother portable and mobile printers. This OEM replacement cable connects RuggedJet 2, 3200, and 4200 series printers, as well as PocketJet 3, 6, 7, and 8 models, to standard grounded wall outlets. Weight of 0.50 lbs keeps the bundled cable package minimal for field technicians moving between job sites—relevant when you're routing power across warehouse floors or temporary staging areas.

Compatibility

Designed for Brother RuggedJet 2, RuggedJet 3200, RuggedJet 4200, PocketJet 3, PocketJet 6, PocketJet 7, and PocketJet 8 printers. Verify your specific model number against your device documentation before ordering to ensure the power inlet matches. Cord length is compact at 2 inches, so plan for proximity to a wall outlet or use an extension cable if the printer will operate more than a few feet from power.

Installation Notes

Disconnect power from the printer before removing the old cord. Align the connector with the printer's AC inlet and insert firmly until seated. Connect the opposite end to a grounded three-prong wall outlet rated for 110V AC, 60 Hz service. No special tools or torque specifications required—hand-insert the connectors. Verify the outlet is properly grounded; using ungrounded outlets risks equipment damage and safety hazards.
