Genuine Honeywell Intermec 406 DPI ultra-high-resolution thermal printhead kit for PX4i, PX4ie, and PX45 printers. Provides 16 dots/mm precision imaging for micro-barcodes, PCB tracking, and pharmaceutical serialization. Factory OEM replacement kit.
Product Overview
The Honeywell Intermec 850-812-900 is an authentic factory replacement 406 DPI (16 dots/mm) thermal printhead engineered specifically for the PX4i, PX4ie, and PX45 high-performance industrial printer series. Developed for extreme-precision labeling applications where compact space demands maximum data capacity, it produces sharp micro 2D matrix symbologies, sub-millimeter characters, and fine line work across an active print width of 4.33 inches (110 mm) at speeds up to 6 inches per second (150 mm/s). The assembly integrates high-density micro-resistor arrays on a rigid aluminum chassis, serving as a direct drop-in replacement to solve pixel burnout, dead element paths, and optical density degradation on high-precision micro-labeling workflows.

Technical Precision & Operational Advisory
- Electrostatic Discharge (ESD) Protection: Always wear a grounded anti-static wrist strap during handling to avoid damaging sensitive internal circuitry.
- Power Isolation Protocols: Complete electrical power-down must be verified prior to disconnecting or reconnecting ribbon cables. Never hot-plug connections.
- Operational Precision: Switch off main line power and unplug the power cord before servicing. Resistors on 406 DPI heads have minimal thermal mass and are vulnerable to electrical transients and electrostatic discharge; ESD wrist grounding is mandatory. Clean printhead surfaces exclusively using pure 99.7% isopropyl alcohol; abrasive cleaners or metal tools will permanently ruin micro-resistor elements. Confirm media and ribbon are rated for 406 DPI printing to prevent excessive darkness settings that cause premature burnout.
- Certified Technician Requirement: Physical mounting and electrical alignment must be conducted exclusively by trained industrial service personnel.
