OEM Industrial High-Density Production Component
Original Roland HEAD, INKJET CG2320 Printhead Assembly (1000029234)
OEM Part Number: 1000029234 | Engineering Description: ASSY, HEAD, INKJET CG2320 | Advanced High-Density Precision Piezoelectric Drop-on-Demand Printhead Module
Next-Generation Industrial MEMS High-Density Architecture Notice
The Roland 1000029234 Printhead Assembly (engineering service code ASSY, HEAD, INKJET CG2320) is an authentic factory-original OEM replacement component engineered for Roland’s high-speed commercial production printing platforms. Built on an advanced high-density Precision MicroPiezo MEMS architecture (I3200-generation industrial family), this 3,200-nozzle module incorporates passivated fluidic manifolds, an anti-wetting coated orifice faceplate, and multi-drop grayscale control designed to sustain continuous multi-shift production.
Product Overview
The Original Roland HEAD, INKJET CG2320 Printhead Assembly (1000029234) is an industrial drop-on-demand (DoD) piezoelectric printhead engineered for high-volume vehicle graphics, retail POP displays, outdoor banners, trade show signage, and industrial custom graphics. Designed to operate within modern high-speed scanning carriage frameworks, the CG2320 assembly provides high firing frequency and drop landing accuracy across long carriage travel cycles.
Engineered with 3,200 active addressable micro-nozzles partitioned across 8 parallel rows (400 nozzles per row), the module delivers an effective 1.33-inch (33.8 mm) active print swathe with native resolutions up to 1200 DPI. Leveraging advanced multi-drop grayscale waveform pulse shaping, the head modulates variable droplet sizes from microscopic highlight dots up to larger drop volumes for dense, uniform solid coverage. The internal manifold construction and cavity bonding are passivated against fluidic degradation, maintaining chemical integrity and continuous nozzle firing stability.

Key Features & Operational Advantages
- 3,200-Nozzle Industrial Throughput: Provides extensive nozzle coverage across a 1.33-inch active print swathe, driving commercial production speeds while maintaining tight drop placement.
- Grayscale Micro-Droplet Precision: Modulates variable drop sizes to yield smooth continuous tones, clean skin gradations, and sharp 2-point micro-lettering without visible grain.
- Passivated Fluid Manifolding: Internal channels and cavity adhesives are chemically passivated to prevent inter-channel cross-leakage and maintain fluid meniscus stability.
- Direct Drop-In OEM Fitment: Built to exact Roland factory tolerances, restoring original droplet trajectory, dot circularity, and carriage height parallelization.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform Specificity & Engineering Code Differentiation: The 1000029234 (CG2320) is engineered specifically for designated next-generation Roland platforms. While structurally sharing the high-density 3,200-nozzle MEMS form factor with the CG2266 (1000026211), internal manifold part allocations, thermistor impedance profiles, and driver board firmware revisions must be matched to your machine. It is completely incompatible with legacy TrueVIS FlexFire heads (6000006702), VS Series DX6/DX7 heads (6701409010), and DX4 heads (1000002201).
2. Mandatory Head-Rank ID Calibration: Following mechanical installation, the technician MUST register the alphanumeric Head-Rank ID value (printed on the barcode label) into the printer via Roland Service Mode. Operating without registering the factory voltage rank leads to incorrect drop velocity, satellite misting, or premature piezo actuator failure.
3. Mandatory FFC Cable & Damper Servicing: Always install brand-new flat flexible head data cables (FFC) concurrently with the printhead. Reusing aged, bent, or ink-contaminated ribbon cables risks shorting the carriage board driver circuits and damaging mainboard driver ICs.
4. Faceplate Maintenance Precautions: Never wipe the delicate coated nozzle faceplate with dry shop wipes or coarse towels. Clean only using approved lint-free foam swabs moistened with genuine Roland cleaning liquid. Regularly inspect and clean the rubber capping station seals and wiper blades to avoid dried ink buildup along the nozzle orifices.
