Toshiba TEC B-672 Series 6-Inch Near-Edge Thermal Printhead (305 DPI)

Catalog Assembly P/N: FMBC0031205 | Verified OEM Master Production P/N: FMBC0044307 (170.6 mm Wide-Format)

Product Overview

The Toshiba TEC B-672 Series Thermal Printhead (referenced under catalog sub-assembly code FMBC0031205 and primary OEM master replacement part number FMBC0044307) is an authentic, extra-wide Near-Edge (floating/corner-edge) printhead engineered specifically for high-throughput Toshiba TEC B-672 and B-682 industrial barcode printing platforms. Operating at 305 DPI (12.0 dots/mm) across an expansive 170.6 mm (6.7-inch) print span, this wide-web printhead produces sharp ODETTE / AIAG automotive master shipping labels, chemical drum compliance placards (GHS), and high-density pallet distribution markings.

By implementing Toshiba TEC's signature Near-Edge cantilever geometry, the micro-heating resistor array is positioned right at the break-away edge of the ceramic substrate. This angled architecture facilitates immediate separation of the thermal transfer ribbon from the label media upon heating, preventing ribbon drag, mechanical wrinkling, and ink scuffing at speeds up to 8 inches per second (203.2 mm/s). Manufactured with an industrial-grade ceramic glaze topcoat on a rigid aluminum extrusion heatsink, the printhead assembly delivers factory-calibrated rank resistance, long dot service life, and native integration with Toshiba TEC’s mechanical Ribbon-Save systems.

Part Identification & Logistics

Technical Specifications

Key Features & Operational Advantages

• 170.6 mm Near-Edge Format: The expansive 6.7-inch active print width enables seamless one-pass printing of large compliance logistics labels without requiring landscape orientation or edge margin reductions.
• Near-Edge Quick Release Architecture: Resistors placed directly at the substrate separation edge prevent molten ribbon drag, eliminating label smudging and ribbon wrinkles during high-speed runs.
• Integrated Ribbon-Save Compatibility: Fully designed to accommodate Toshiba TEC’s automatic mechanical Ribbon-Save solenoid systems, preserving consumable costs across intermittent print jobs.
• OEM Dot Resistance Matching: Calibrated strictly to Toshiba TEC factory strobe algorithms, ensuring consistent optical print density across all 2,048 micro-resistor elements.

Technical Precision & Operational Advisory

PART NUMBER & GENERATION CROSS-REFERENCE: Catalog reference FMBC0031205 maps to primary OEM master replacement part number FMBC0044307 (used across B-672 and B-682 series). Do not confuse this unit with older flat-head 6-inch models like the B-63 (OEM P/N: 24325000043 / FMBC0018502 at 203 DPI) or later-generation B-SX6T printheads (7FM01584100). Verify existing bracket design and OEM part numbering on the defective printhead prior to installation.

ELECTROSTATIC DISCHARGE (ESD) DANGER: With an extended array of integrated shift-register driver ICs, this 305 DPI printhead is exceptionally sensitive to electrostatic breakdown. Technicians must wear an earth-grounded ESD wrist strap (1 MΩ resistance) and operate on conductive dissipative mats. Never touch terminal contacts or the exposed ceramic edge array directly with bare skin.

MANDATORY ELECTRICAL ISOLATION: Always power OFF the printer and remove the AC power cord from the mains supply prior to removing or reconnecting the FPC ribbon cable harness. Connecting or disconnecting data cables while DC standby logic power is active will cause instant electrical arcing, blowing internal driver circuits and damaging the printer mainboard.

RIBBON FORMULATION CRITICAL WARNING: The B-672 uses industrial Near-Edge printing technology. Using standard "flat-head" thermal transfer ribbons will lead to severe smudging, incomplete ink transfer, poor barcode readability, and excessive printhead wear. Always load certified Near-Edge Wax/Resin or Near-Edge Resin thermal transfer ribbons. Clean the array with 99.7%+ electronic-grade IPA swabs at every ribbon change.

Compatible Models & Systems

*Platform Successor Reference: The B-672 / B-682 platform line was succeeded by the B-SX6T series (7FM01584100). Ensure proper physical bracket alignment before deployment.

Terms, Warranty & Customer Protection

Genuine OEM Verification: Procured through verified industrial supply chains, this product is guaranteed original Toshiba TEC manufactured stock delivered in factory-sealed antistatic packaging.

Dead-On-Arrival (DOA) Protection: Covered by an industry-standard 30-day DOA policy covering factory material defects or initial electrical failure upon arrival. Any claim must be submitted within 30 days of shipment receipt, accompanied by high-resolution photographs of the part serial label, outer ESD packaging, and a diagnostic hardware test print performed by a certified technician.

Non-Returnable Policy for Consumable Parts: Precision thermal printheads are highly sensitive electronic components vulnerable to electrostatic discharge, incorrect pin alignment, mechanical scratching, and ungrounded electrical surges. Consequently, this component is strictly non-returnable and non-refundable once the factory antistatic packaging seal has been broken.
