OEM Replacement Component
Toshiba TEC B-852 Series 8.5-Inch Thermal Printhead (300 DPI)
OEM Part Number: FMBC0049202 | Wide-Web High-Resolution Direct Thermal & Thermal Transfer Line Head
Product Overview
The Toshiba TEC FMBC0049202 is a genuine original equipment manufacturer (OEM) wide-format thermal printhead designed specifically for the Toshiba TEC B-852 and B-852-R industrial printer families. Engineered to deliver high-density output across an expansive 8.5-inch (216.8 mm) continuous active print width, this unit operates at a native resolution of 300 DPI (11.8 dots/mm) with a tight 0.084 mm dot pitch.
Manufactured with an ultra-durable thin/thick-film hybrid ceramic substrate and an abrasion-resistant protective glaze, the FMBC0049202 ensures uniform thermal diffusion across all 2,560 micro-heating elements. It provides critical edge-to-edge optical density and crisp line definition for high-density 2D Data Matrix codes, complex chemical GHS warning pictograms, wide pallet transport labels, and compliance tagging systems without optical distortion or element flare.

Key Features & Operational Advantages
- True Wide-Format 300 DPI Resolution: Employs 2,560 microscopic heating dots to produce razor-sharp micro-text, small 2D codes, and high-definition logotypes across full A4-equivalent and 8.5-inch wide web stocks.
- Reinforced Protective Overcoat: Specialized dielectric glazed surface shields the resistive elements against mechanical micro-abrasion from synthetics and paper dust accumulation during long print runs.
- Uniform Thermal Dissipation: High-conductivity extruded aluminum heatsink assembly maintains thermal stability across the entire 216.8 mm span, preventing element overheating and thermal ghosting.
- Direct OEM Factory Calibration: Matches factory resistance specifications and logic timings, allowing simple plug-and-play mechanical alignment without recalibrating the motherboard driver stages.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Mandatory ESD Precautions: The driver ICs embedded on the ceramic substrate are highly sensitive to electrostatic discharge (Class 1 ESD). Technicians must wear a grounded ESD wrist strap and work on a dissipative mat. Avoid physical contact with the ceramic dot array or signal connector terminals.
2. Complete Power Isolation: Always shut off the main printer switch and unplug the AC power cable prior to unseating the carriage assembly or disconnecting the signal cables. Disconnecting or seating cable harnesses while the system board is energized will destroy the logic gates and void all replacement coverage.
3. Wide-Span Carriage Pressure Alignment: Across an 8.5-inch printline, uneven mechanical head pressure causes ribbon wrinkling, premature edge element burn, and diagonal density dropouts. Always rebalance the dual pressure toggle dials following printhead seating.
4. Alcohol Cleaning Standard: Clean the dot line exclusively using a lint-free swab saturated with 99% pure electronic-grade Isopropyl Alcohol (IPA). Allow the array to dry completely before restoring power. Never use sharp metallic blades or abrasive cleaners to clear adhesive build-up.
Compatible Models & Systems
| System Series | Native Resolution | Model Designation |
|---|---|---|
| Toshiba TEC B-852 Series | 300 DPI (11.8 dots/mm) | B-852-TS22-QM-R / B-852-R |
| Toshiba TEC Wide Web Platform | 300 DPI (11.8 dots/mm) | B-852 Series Industrial Units |
*Model Differentiation Note: Do not confuse with the 203 DPI wide-web head (Part # FMBC0020402 for B-832) or older 300 DPI wide units (FMBC0089706). Cross-check the existing printhead part number and printer configuration tag prior to unsealing the component.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Unopened Factory Original Genuine OEM Part in Factory Sealed Anti-Static Packaging.
Warranty Scope: Covered by standard manufacturer DOA replacement protection against material and electrical manufacturing defects upon arrival. Operating lifespan is governed by runtime duty cycles, media abrasive properties, operating heat settings, and preventative cleaning protocols.
Return Policy: Precision industrial electronic consumable. Items that have had their anti-static security seal broken, have been mechanically mounted, or energized through a host printer are strictly non-returnable. Please confirm your OEM part number with our technical support team before breaking the factory seal.
