OEM Replacement Component
Original HP 886 Dual-Color Universal Latex Printhead (G0Z21A)
OEM Part Number: G0Z21A (HP No. 886) | Industrial High-Definition Recirculating Thermal Inkjet (TIJ 4.0) Printhead
Part Specification Notice (SKU Channel Assignment)
In official HP industrial engineering catalogs, G0Z21A is designated as the HP 886 Dual-Color Universal Process Printhead (servicing chromatic pairs across Cyan, Magenta, Yellow, Black, Light Cyan, and Light Magenta). In contrast, the dedicated White (W) printhead module is officially assigned under part number G0Z24A (integrating with automated offline storage chambers). The technical documentation below provides the authentic OEM engineering specification for G0Z21A.
Product Overview
The Original HP 886 Dual-Color Universal Latex Printhead (G0Z21A) is an authentic original equipment manufacturer dual-channel thermal drop-on-demand (DoD) inkjet printhead engineered specifically for high-capacity hybrid flatbed and roll production systems, including the HP Latex R1000, R1000 Plus, R2000, R2000 Plus Series, as well as the HP Latex 2700 / 2700 W and industrial FS50 / FS60 platforms. Operating as the primary chromatic imaging engine within HP’s 4th-generation industrial latex architecture, the G0Z21A functions as a universal, slot-independent module that dynamically configures to its assigned process color channel pair upon installation and fluidic priming.
Housing 10,560 active addressable nozzles (5,280 nozzles dedicated per channel across dual interleaved arrays) with non-circular nozzle orifice geometry, the HP 886 printhead ejects calibrated 10 picoliter (pL) micro-droplets at native output resolutions up to 1200 × 1200 optimized DPI. It features active micro-recirculation behind the nozzle firing chambers to maintain fluid homogeneity, eliminate pigment sedimentation, and prevent nozzle dehydration during sustained printing. Integrated with onboard cryptographic EEPROM calibration and closed-loop thermal compensation, it works in synchronization with the printer's automated Optical Drop Detector (ODD) to execute active nozzle health checks and dynamic passive redundancy mapping across rigid boards, corrugated packaging, and flexible roll vinyls.

Key Features & Operational Advantages
- Universal Process Architecture: A single OEM SKU (G0Z21A) services all color channel slots across HP Latex R-Series and 2700-series carriages, streamlining spare parts inventory and reducing operational complexity.
- Active Internal Micro-Recirculation: Continuously circulates ink directly behind the silicon nozzle plate, preventing pigment sedimentation, crusting, and nozzle dropouts without wasting ink in routine purge cycles.
- High-Speed Industrial Jetting (10,560 Nozzles): Accommodates heavy production throughput across wide flatbed platforms and 3.2-meter rolls, maintaining uniform droplet trajectory across variable media thicknesses.
- Active Optical Drop Detection & Substitution: Communicates with the printer’s carriage Optical Drop Detector (ODD) to identify non-firing nozzles automatically and map adjacent redundant nozzles to prevent banding without operator intervention.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Slot Priming & Irreversible Channel Locking: While the G0Z21A printhead is physically universal prior to first use, once inserted into a specific carriage slot and charged with ink, its internal fluidic channels and onboard smart chip lock to that assigned color pair. Never move a primed printhead to a different color slot, as this will cause catastrophic cross-contamination.
2. Platform Differentiation from HP 831, HP 871, and HP 881: The HP 886 series is engineered strictly for HP Latex R-Series flatbeds (R1000/R2000), Latex 2700, and FS50/FS60 platforms. It cannot be used in roll-to-roll 3.2-meter Latex 1500/3000 engines (which require HP 881 CR327A–CR331A) or 64-inch roll engines (HP 831 or HP 871). Physical chassis keying and smart chip handshake protocols lock out non-matching heads.
3. Rigid Board Vacuum & Curing Heat Stress: When switching between thin films and thick rigid boards up to 50 mm (2 in), ensure automatic carriage height alignment is verified through the internal print server (IPS). Incorrect carriage height can cause board strikes against the nozzle plate or excessive heat exposure from the curing module.
4. Packaging & Electrical Contact Protection: Keep the printhead sealed in its factory vacuum blister pack until immediately before insertion. Never touch the rear electrical gold contact pins or the silicon nozzle orifice plate with bare hands. Finger oils and electrostatic discharge (ESD) will lead to smart chip authentication faults.

*Model Differentiation Note: In HP Latex R-Series and 2700-series carriages, the G0Z21A Universal Color head operates in synchronization with companion HP 886 printhead SKUs: G0Z22A (Optimizer), G0Z23A (Overcoat), and G0Z24A (White). Always verify the module part number and destination carriage slot prior to unsealing the foil packaging.
