Toshiba TEC B-572 Series 5-Inch Near-Edge Thermal Printhead (305 DPI)

Catalog P/N: FMBC0031105 | Official OEM Service Part Number: FMBB0050103 (305 DPI / 127.5 mm Wide-Format)

Product Overview

The Toshiba TEC B-572 Series 305 DPI Thermal Printhead (referenced under catalog assembly code FMBC0031105 and official OEM service master part number FMBB0050103) is an authentic, wide-format Near-Edge (floating/corner-edge) replacement printhead engineered specifically for the rugged Toshiba TEC B-572 industrial platform. Built for continuous, high-volume production lines, chemical drum labeling, pallet tracking, and wide logistics compliance formats, it features an extended print span of up to 127.5 mm (5.02 inches) running at a high-definition 305 DPI (12.0 dots/mm) resolution.

Leveraging Toshiba TEC's signature Near-Edge cantilever geometry, the resistive elements fire at the extreme discharge perimeter of the ceramic substrate. This allows instant ribbon peeling from the printed substrate, eliminating ribbon drag, trailing ink smudge, and wrinkle formation at production speeds up to 8 inches per second (203.2 mm/sec). Fabricated with an abrasive-resistant silicon/ceramic topcoat on an integrated aluminum extrusion heatsink, the assembly delivers factory-matched rank resistance, seamless integration with Toshiba TEC’s mechanical Ribbon-Save solenoid systems, and extended thermal dot longevity.

Part Identification & Logistics

Technical Specifications

Key Features & Operational Advantages

• True Near-Edge 5-Inch Architecture: Extended 127.5 mm array allows high-throughput wide labeling up to 8 ips without trailing ribbon drag, ribbon wrinkling, or mechanical friction across synthetic media.
• Integrated Ribbon-Save Compatibility: Fully compatible with Toshiba TEC's automatic ribbon-save motor mechanism, allowing the head assembly to disengage during non-printed areas to optimize consumable usage.
• High-Density 305 DPI Precision: Delivers sharp rendering of complex 2D DataMatrix symbologies, high-density linear barcodes, chemical GHS hazard pictograms, and small regulatory text.
• OEM Rank Resistance Calibration: Built strictly to Toshiba TEC factory strobe profiles, preventing edge burnout, thermal bleed-through, and premature element failure across the wider thermal array.

Technical Precision & Operational Advisory

WIDTH & MODEL COMPATIBILITY CLARIFICATION: The B-572 is a dedicated 5-inch (127.5 mm) wide-format printing engine. This printhead assembly (FMBC0031105 / FMBB0050103) is mechanically longer than 4-inch printheads (such as the B-472 at 203 DPI or B-482 at 300 DPI) and cannot be installed into 4-inch B-400 series chassis. Verify your printer chassis model tag confirms "B-572" before unsealing.

ELECTROSTATIC DISCHARGE (ESD) DANGER: Thin-film micro-heating elements and onboard IC driver modules are extremely susceptible to catastrophic static damage. Certified ESD wristbands grounded via a 1 MΩ resistor and static-dissipative workstations are strictly required during handling and mounting. Do NOT touch connector pins or the ceramic heating burn edge with bare hands.

MANDATORY ELECTRICAL ISOLATION: Always power OFF the B-572 printer and disconnect the AC line power cord prior to servicing. Connecting or disconnecting FPC ribbon cables while DC standby logic power is active will cause instant electrical arcing, blowing internal driver circuits and damaging the main control board.

RIBBON FORMULATION CRITICAL WARNING: The B-572 utilizes Near-Edge thermal technology. Using conventional "flat-head" thermal transfer ribbons will result in incomplete ink release, severe smudging, barcode scan failures, and excessive printhead wear. Always load certified Near-Edge Wax/Resin or Near-Edge Resin ribbons, and clean the print edge solely with 99.7%+ electronic-grade IPA swabs at every ribbon roll change.

Compatible Models & Systems

*Platform Successor Reference: The B-572 platform was succeeded by the Toshiba TEC B-SX5T series (which utilizes printhead part number 7FM01641100). Verify existing bracket design and OEM part numbering before procurement.

Terms, Warranty & Customer Protection

Genuine OEM Verification: Procured strictly via certified industrial supply chains, this printhead is guaranteed 100% brand new, authentic Toshiba TEC / Kyocera OEM production inventory shipped in sealed antistatic protective packaging.

Dead-On-Arrival (DOA) Protection: Covered by an industry-standard 30-day DOA policy covering factory material defects or initial electrical dead dots upon delivery. Any claim must be submitted within 30 days of shipment receipt, accompanied by high-resolution photographs of the part serial tag, unblemished ESD packaging, and a diagnostic print test 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.
