Original HP 72 Magenta and Cyan Printhead (C9383A)
OEM Part Number: C9383A (HP No. 72) | Dual-Color Thermal Inkjet (TIJ 3.0) Replacement Printhead
Product Overview
The Original HP 72 Magenta and Cyan Printhead (C9383A) is an authentic original equipment manufacturer dual-color thermal inkjet (TIJ) printhead component engineered specifically for HP DesignJet technical and production plotters. Serving as the primary chromatic color engine within HP’s 6-color printing system, the C9383A printhead delivers crisp color contrast, saturated primaries, and smooth secondary blends essential for high-precision AEC architectural plans, GIS topological mapping, 3D color renders, and commercial presentations.
Housing 2,112 active nozzles (1,056 nozzles dedicated per color channel across dual interleaved arrays), the HP 72 C9383A printhead deposits calibrated 6 picoliter (pL) micro-droplets at native print resolutions up to 2400 × 1200 optimized DPI. Equipped with HP’s built-in Smart Printing Technology, the onboard cryptographic EEPROM continuously communicates with the carriage electronics to monitor nozzle health, dynamically adjust thermal pulse firing parameters, and execute automated drop detection and channel remapping. Built for use with genuine HP 72 dye-based Magenta and Cyan inks, the printhead ensures smooth continuous-tone transitions, tight vector line accuracy, and consistent jetting performance on both technical bond and presentation media.

Key Features & Operational Advantages
- Vibrant Primary Color Reproduction: Magenta and Cyan dye channels provide brilliant optical saturation for high-impact 3D technical renderings, aerial satellite maps, and sharp color-coded vector linework.
- Crisp 6 pL Micro-Drop Definition: Generates tight line acutance down to 0.02 mm, smooth graphic fills, and clean text characters without bleed on standard technical bond and presentation substrates.
- Intelligent Built-in Diagnostics: Interacts with the plotter's optical drop sensor (ODS) to detect non-firing nozzles automatically and perform software substitution routines to eliminate horizontal banding.
- User-Replaceable Modular Format: Snaps directly into the DesignJet carriage cradle with an integrated locking latch, requiring no technician tools or external priming equipment.
CRITICAL TECHNICAL & OPERATIONAL ADVISORY
1. Automated Alignment & Media Loading: After seating the C9383A printhead and locking the carriage latch, allow the plotter to perform its automatic printhead alignment routine. Ensure clean coated or bond paper is loaded on the roll/tray so the optical sensor can scan the calibration patterns without read errors.
2. Electrical Contact Pad Integrity: Never touch the gold contact array or the nozzle orifice faceplate with bare fingers. Finger oils and electrostatic discharge (ESD) can degrade signal integrity and cause communication or heater faults. If contaminated, clean the pads gently using a lint-free cloth lightly dampened with distilled water.
3. Service Station Maintenance: Periodically inspect the service station wipers and capping seals. Buildup of dried ink residue on wiper blades can scrape across the nozzle plate, causing cross-channel contamination or permanent nozzle clogging.
4. Packaging & Expiration Management: Keep the printhead sealed in its protective foil blister pack until immediately prior to physical installation to prevent nozzle dehydration. Check the "Install By" date printed on the exterior carton to ensure optimal firing velocity and fluid freshness.

*Model Differentiation Note: The C9383A printhead is dedicated strictly to the Magenta and Cyan color channel pair within HP 72 systems. It cannot be substituted for other HP 72 dual-channel pairs: C9380A (Gray and Photo Black) or C9384A (Matte Black and Yellow). Additionally, despite sharing a similar physical chassis design with the HP 70 series (C9404A–C9410A) and HP 73 series, the internal keying notches and EEPROM firmware are specific to HP 72 platforms and are not interchangeable.
Terms, Warranty & Customer Protection
Condition: 100% Brand New, Genuine OEM Factory-Original HP Component sealed in official blister pack with factory storage fluid intact.
HP Manufacturer Warranty: Warranted by HP against defects in materials and workmanship until the "Warranty Ends" date printed on the product packaging or until the OEM ink consumption limit is reached, whichever comes first.
Return Policy: Precision electronic consumable. Unopened, factory-sealed boxes are eligible for return under standard commercial terms. Once the outer blister seal is opened, protective orange clip removed, or the head seated in a carriage, returns cannot be accepted due to fluid cross-contamination and activation of the internal smart chip.
