OEM Replacement Component

Toshiba TEC B-SP2D Series 2-Inch Mobile Thermal Printhead (203 DPI)

OEM Part Number: FMBC0049402 | Legacy Ultra-Compact Direct Thermal Mobile Line Head Assembly

Product Overview

The Toshiba TEC FMBC0049402 (also cross-referenced under Toshiba supply code G0-00582000) is an authentic original equipment manufacturer (OEM) replacement thermal printhead engineered specifically for the Toshiba TEC B-SP2D portable mobile printer series. Tailored for lightweight mobile receipt issuance, direct store delivery (DSD), parking violation ticketing, queue-busting retail, and warehouse shelf-edge markdown labeling, this printhead assembly delivers dependable 203 DPI (8.0 dots/mm) resolution across an active 1.89-inch (48.0 mm) continuous print span.

Constructed with a thin-film ceramic resistive array consisting of 384 heating elements, the FMBC0049402 is optimized to operate on battery-conserving low-voltage circuits while sustaining high optical contrast. Coated with a protective dielectric glass glaze, it defends the resistive array against abrasive friction and chemical topcoats common to direct thermal receipt rolls and die-cut tags. Factory-integrated pivot tabs and a compact aluminum heatsink base ensure drop-in mechanical alignment into the B-SP2D clamshell carriage, sustaining print speeds up to 80 mm/sec (approx. 3.15 ips).

Key Features & Operational Advantages

Battery-Conscious Micro-Heater Array: Engineered with low-resistance thin-film elements designed to achieve high optical darkness while preserving the charge of the printer's 7.4V lithium-ion battery.
Compact Form-Factor Engineering: Slim profile and integrated locator notches perfectly fit the clamshell mechanism of the B-SP2D mobile chassis, facilitating rapid field servicing.
Protective Glass Glaze Overcoat: Shields the heating array from continuous paper-dust abrasion and chemical reactions caused by top-coated thermal papers.
Drop-In Factory Resistance Calibration: Matches the factory pulse-timing strobe curves in B-SP2D firmware, ensuring clear text, barcodes, and logos without manual voltage calibration.

CRITICAL TECHNICAL & OPERATIONAL ADVISORY

1. Mandatory ESD Precautions: Microscopic thin-film heater elements and onboard 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 mobile printer and remove the lithium-ion battery pack before replacing the printhead. Disconnecting or seating the flexible connector tail while the motherboard is powered will cause instantaneous gate blowout in the driver ICs and permanently destroy the head.

3. FPC Harness Care: The flexible printed circuit (FPC) tail is fragile. Do not crease, twist, or exert excessive pulling tension during insertion. Ensure the ZIF connector lock on the printer mainboard is fully opened before sliding the ribbon cable into position.

4. Preventive Cleaning Regimen: Direct thermal paper generates fine paper dust and chemical residue. Regularly clean the printline using a lint-free swab saturated with 99.7% electronic-grade Isopropyl Alcohol (IPA). Allow the array to dry completely before closing the carriage and powering on. Never use razor blades or metal implements on the ceramic face.

Compatible Models & Systems

*Model Differentiation Note: This printhead is dedicated strictly to the legacy 2-inch B-SP2D mobile series. It is NOT physically or electrically interchangeable with newer B-FP2D mobile printheads (Part # FMBC0147601, 54 mm print width) nor B-EP2DL units (Part # FMBC0084001). Check the model code on your printer rating plate 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: Covered by standard manufacturer DOA replacement protection against electrical continuity failures and physical manufacturing defects upon initial arrival. Operating longevity is governed by media abrasiveness, environmental exposure, operating heat levels, and adherence to routine cleaning maintenance.

Return Policy: Precision 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.
