ARCHITECTURAL OVERVIEW
Compact Industrial Thermal Deposition & Retail Scale Print Engine
The Bizerba KF2002-GH50B Thermal Printhead (OEM P/N: 7105840000 / 71058400000) is an authentic OEM replacement transducer engineered by Kyocera Corporation specifically for Bizerba compact industrial label printers and commercial retail system scales. Developed for continuous, high-duty service cycles across supermarket deli counters, butcheries, bakery pre-pack stations, and automated benchtop labeling units, this printhead delivers crisp variable weight data, nutritional information tables, and high-contrast retail barcodes (EAN/UPC-8, EAN/UPC-13, Code 128, Code 39) with razor-sharp edge definition.
Engineered on a precision thick-film ceramic resistor substrate, the printing line integrates 432 microscopic heating elements calibrated at 8 dots per millimeter (nominal 200/203 DPI) across a 54 mm (2.13 inch) active print swath. The thermal resistor array is shielded with a specialized Diamond-Like Carbon (DLC) glaze overcoat, delivering robust mechanical abrasion resistance against chemical top-coatings on direct thermal paper and synthetic label stocks. This micro-passivation layer prevents early dot pitting, electrostatic pinhole punctures, and residue buildup during daily retail print operations.
Equipped with a machined aluminum structural heat sink, the assembly ensures rapid thermal dissipation away from the dot line to eliminate thermal latency and ghosting at print speeds up to 100 mm/s. The unit features built-in high-precision negative temperature coefficient (NTC) thermistors for continuous strobe energy compensation and factory-soldered high-reliability logic driver ICs. Every genuine unit is factory resistance-ranked, vacuum-sealed in cleanroom anti-static ESD packaging, and delivered ready for immediate drop-in replacement.
CRITICAL SYSTEM CROSS-CHECK: Verify the alphanumeric marking stamped on the rear aluminum bracket before installation. The "KF2002-GH50B" designates a 54 mm active print array designed for 58 mm chassis mechanisms. Do not interchange with 80 mm models (such as KF2002-GL14B / P/N 71021550000) or 4-inch modules (KD2004 series), as physical width, alignment pegs, and electrical pinouts differ substantially.
ENGINEERING REFERENCE
Identification Notes & Core Distinction
| Reference Standard | Technical Description & Interoperability Context |
|---|---|
| Primary OEM Part Number | 7105840000 / 71058400000 – Official Bizerba spare part reference for the 54 mm direct thermal print carriage in GLP 58 and retail scale systems. |
| Kyocera Core Sub-Assembly | KF2002-GH50B – Manufacturer factory designation identifying the 8 dots/mm ceramic thick-film array, driver IC architecture, and mounting geometry. |
| Associated Core Engine Variations | KF2002 Series (GH / GK / GL revisions) – Specific suffix indicates factory mounting flange position and connector angle; GH50B must be preserved for exact mechanical fit. |
NOTICE: Do not attempt to mount the 54 mm KF2002-GH50B into printers configured for 80 mm heads (e.g., GLP 80 / SC II series using KF2002-GL14B or KD2002-DC92C) or 104 mm heads (KD2004 series). Mismatched chassis footprints will prevent print carriage latching and cause driver board failure.

FIELD ADVISORY
Technical Precision & Installation Warning
CAUTION: Installation and replacement of this thermal printhead must be conducted exclusively by qualified maintenance technicians adhering strictly to OEM safety protocols.
- Electrostatic Discharge (ESD) Protection: Wear a grounded anti-static wrist strap during servicing. The micro-resistor heating line and internal shift register arrays are vulnerable to static voltage puncture.
- Complete Power Isolation (No Hot-Swapping): Disconnect AC mains power from the scale or printer terminal before opening the carriage mechanism. Never connect or disconnect the printhead cable while the machine is energized. Live mating induces transient inductive surges that destroy driver ICs and mainboard logic circuits.
- Harness & Pin Alignment Inspection: Check the connecting wiring harness for pinched insulation, pin oxidation, or bent leads. Insert the plug squarely and ensure locking tabs snap fully into place without skewed force.
- Platen Roller Cleaning & Pressure Balance: Clean the rubber platen roller thoroughly with 99% pure electronic-grade isopropyl alcohol (IPA) before seating the new printhead. Inspect the platen for grooves or flat spots; an uneven platen will cause premature failure of the new ceramic element line.
- Handling Factory-Sealed Unit: Never touch the glazed thermal print line with bare hands; skin oils carbonize under operational heat and create localized thermal hot-spots. Clean solely with lint-free swabs saturated in pure IPA prior to first power-up.
- Resistance Rank Calibration Entry: Check the printed average resistance ranking on the Kyocera barcode label and calibrate the terminal service menu accordingly. Driving a printhead at an uncalibrated strobe voltage will cause faint output or premature element burnout.
