Product Overview

The Original HP 881 Light Magenta and Light Cyan Latex Printhead is an authentic original equipment manufacturer dual-color industrial thermal drop-on-demand (DoD) inkjet printhead engineered specifically for heavy production 3.2-meter (126-inch) industrial systems, including the HP Latex 1500, Latex 3000, Latex 3100, and Latex 3500 Series. Operating as the primary photographic highlight and delicate skin-tone imaging engine within HP’s 7-head industrial latex carriage, this printhead governs dilute Light Magenta (LM) and Light Cyan (LC) inks to produce grain-free transitions, smooth sky gradients, and subtle flesh-tone highlights without visible dot stippling.

Housing 10,560 active addressable nozzles (5,280 nozzles dedicated per channel across high-density staggered arrays), the HP 881 printhead ejects calibrated 12 picoliter (pL) micro-droplets at native output resolutions up to 1200 × 1200 optimized DPI. Equipped with HP’s built-in Smart Printing Technology and industrial onboard cryptographic EEPROM calibration, it continuously monitors firing pulses, compensates for ambient thermal fluctuations caused by adjacent high-energy curing heaters, and communicates directly with the printer's automated Optical Drop Detector (ODD) to execute real-time nozzle health validation and dynamic nozzle substitution.

Key Features & Operational Advantages

• Grain-Free Highlight Deposition: Low-density Light Magenta and Light Cyan pigment concentrations eliminate visible dot graininess in large-area pastel backgrounds, vehicle wraps, and cosmetic close-up retail graphics.
• High-Speed Industrial Jetting (10,560 Nozzles): Delivers uniform fluid coverage across wide 3.2-meter spans at linear print speeds up to 180 m²/hr (1,940 ft²/hr) on industrial rolls.
• Latex Polymer Thermal Stability: The internal micro-fluidic channels are specially treated to prevent latex polymer binder coagulations and nozzle faceplate crusting caused by the radiant heat of nearby curing lamps.
• Active Optical Drop Detection: Integrates with the carriage Optical Drop Detector (ODD) to monitor individual nozzle status dynamically, compensating with adjacent nozzles to prevent banding defects.

Compatible Models & Systems

*Model Differentiation Note: In 3.2-meter industrial platforms (Latex 1500/3000/3100/3500), the HP 881 carriage uses seven user-replaceable printhead slots: CR328A (Cyan/Black), CR329A (Magenta/Yellow), CR330A (Light Cyan/Light Magenta), and CR331A (HP Latex Optimizer). Always verify the correct color channel module before breaking the outer protective packaging seal.
