OEM Replacement Component
Toshiba TEC B-EX4T1-TS Series 4-Inch Thermal Printhead (305 DPI)
OEM Part Number: FMBC0094702 | Genuine Industrial Near-Edge Direct Thermal & Thermal Transfer Line Head Assembly
Product Overview
The Toshiba TEC FMBC0094702 is an authentic original equipment manufacturer (OEM) replacement thermal printhead engineered specifically for the premium Toshiba TEC B-EX4T1-TS industrial printer series. Utilizing Toshiba's advanced Near-Edge (corner-edge) printhead architecture, this unit delivers high-definition 305 DPI (12.0 dots/mm) resolution across an active 4.09-inch (104.0 mm) print width, maintaining sharp dot fidelity at sustained production speeds up to 14 inches per second.
Engineered with a ceramic substrate featuring edge-positioned micro-resistors and a wear-resistant protective glaze, the FMBC0094702 provides steep ribbon take-off geometry immediately following heat transfer. This specialized near-edge profile minimizes ribbon friction, supports Toshiba's mechanical ribbon-save capability, and prevents static or drag artifacts, delivering precise edge definition for high-density 2D Data Matrix codes, pharmaceutical tracking labels, and intricate regulatory symbologies.

Key Features & Operational Advantages
- High-Density 305 DPI Near-Edge Matrix: Employs 1,248 individual microscopic heating elements along the beveled substrate edge, delivering crisp rendering of small 2D codes, regulatory pictograms, and micro-fonts at high speeds.
- Immediate Ribbon Peeling Angle: The corner-edge layout releases ribbon backing instantly after energy discharge, eliminating drag marks, static friction, and thermal bleed across rapid duty cycles.
- Ribbon-Save Mechanism Compatibility: Fully certified for synchronization with Toshiba TEC’s optional ribbon-saving hardware, allowing the printhead to maintain register during intermittent feed cycles without wasting ribbon.
- Drop-In Factory Calibration: Pre-matched factory resistance ratings align directly with the B-EX4T1 mainboard drive tables, eliminating manual voltage adjustments and ensuring uniform optical density across the printline.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Mandatory ESD Precautions: Embedded 305 DPI near-edge resistive arrays and driver shift registers are Class 1 ESD-sensitive components. Technicians must wear a grounded ESD wrist strap and work on a static-dissipative work surface. Never touch the ceramic dot array or signal connector terminals directly.
2. Complete Power Isolation: Always power off the printer and disconnect the main AC power cord prior to replacing the printhead. Disconnecting or seating cable harnesses while the power supply is energized will cause instantaneous gate blowout in the driver ICs and permanently destroy the head.
3. Near-Edge vs. Flat-Head Architecture: The B-EX4T1 utilizes a proprietary Near-Edge printhead. It is NOT physically or electrically compatible with Flat-Head models (such as the B-EX4T2 or B-EX4D2 series). Installing this unit into a flat-head printer will cause severe carriage damage and immediate failure.
4. Preventive Cleaning & Ribbon Matching: Always use dedicated Near-Edge formulated thermal transfer ribbons to prevent premature element wear. Clean the beveled printline after every ribbon change using a lint-free swab saturated with 99.7% electronic-grade Isopropyl Alcohol (IPA). Allow the array to dry completely before applying power. Never use metallic tools or abrasives on the glazed edge.
Compatible Models & Systems
| System Family | Native Resolution | Supported Models |
|---|---|---|
| Toshiba TEC B-EX4T1 Series | 305 DPI (12.0 dots/mm) | B-EX4T1-TS12-QM-R (Near-Edge) |
| Toshiba TEC Near-Edge Industrial | 305 DPI (12.0 dots/mm) | B-EX4T1 Type 1 TS Chassis Models |
*Model Differentiation Note: This printhead is dedicated strictly to the Near-Edge 305 DPI B-EX4T1-TS series. It is NOT compatible with 203 DPI Near-Edge models (B-EX4T1-GS, Part # FMBC0094602), nor with Flat-Head Type 2 models (B-EX4T2 series). Check the serial configuration label on the printer frame prior to unsealing the component.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Unopened Factory Original Genuine OEM Component in Factory-Sealed Anti-Static Packaging.
Warranty Scope: Protected by standard manufacturer DOA replacement coverage against electrical continuity failures and physical manufacturing defects upon initial arrival. Operating longevity is governed by media abrasiveness, ribbon chemistry compatibility, operational darkness levels, and routine cleaning compliance.
Return Policy: Precision industrial electronic consumable. Due to sensitivity to electrostatic discharge and inherent operational wear characteristics, components that have been unsealed from their protective static-shielding bag, mounted, or energized on a printer cannot be returned or restocked under standard commercial terms. Please confirm your printer model and OEM part number with technical support prior to unsealing.
