OEM High-Speed Production Component
Original Roland HEAD, INKJET CG2266 Printhead Assembly (1000026211)
OEM Part Number: 1000026211 | Engineering Description: ASSY, HEAD, INKJET CG2266 | Industrial High-Density Multi-Drop Piezoelectric DoD Printhead Module
Next-Generation Industrial High-Density Architecture Notice
The Roland 1000026211 Printhead Assembly (engineering designation ASSY, HEAD, INKJET CG2266) is an authentic OEM replacement module engineered specifically for Roland's latest high-throughput eco-solvent and UV production engines (including the Roland D-STRiX ER-642, ER-641, XP-640, and designated TrueVIS UG-642 platforms). Built on an advanced high-density industrial MicroPiezo MEMS architecture (I3200-series platform derivative), this assembly features a staggered 4-row/8-channel layout delivering a 1.33-inch active print swathe, variable droplet grayscale control, and passivated fluid cavities engineered for high-speed continuous jetting.
Product Overview
The Original Roland HEAD, INKJET CG2266 Printhead Assembly (1000026211) is an industrial drop-on-demand (DoD) piezoelectric printhead engineered for high-volume commercial graphics, vehicle liveries, outdoor signage, backlit displays, soft signage, and packaging mockups. Deployed in dual-head staggered carriage configurations (such as the ER-642 and UG-642) or single-head setups (ER-641), this module delivers production speeds up to 75 m²/h while maintaining micron-level dot roundness and placement accuracy.
Configured with 3,200 active addressable micro-nozzles partitioned across 4 or 8 channels (400 nozzles per line across 8 rows, or 800 nozzles per line across 4 rows), the CG2266 architecture achieves native optical output resolutions up to 1200 DPI. Leveraging advanced multi-drop grayscale waveform pulse shaping, the head discharges microscopic highlight droplets for grain-free photographic vignettes and razor-sharp 2-point micro-lettering, dynamically expanding to heavier drop masses for dense solid color floods. Its passivated fluidic manifolds and coated orifice faceplate provide high chemical durability against modern eco-solvent diluents and UV-curable monomers.

Key Features & Operational Advantages
- 3,200-Nozzle Industrial Throughput: Massive nozzle density across a 1.33-inch print swathe enables continuous production speeds up to 75 m²/h with uniform drop placement.
- Grayscale Micro-Droplet Precision: Modulates variable drop sizes to achieve photorealistic continuous tones, smooth skin gradations, and sharp 2-point micro-lettering without dot grain.
- Fortified Fluid Passivations: Internal cavity chambers and manifold bonding resins resist modern aggressive solvent carriers and reactive UV monomers without joint delamination.
- Direct Drop-In OEM Fitment: Built to exact Roland factory tolerances, restoring original droplet velocity, dot circularity, and carriage height parallelization.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform Incompatibility with Legacy Roland Series: The 1000026211 (CG2266) is engineered specifically for next-generation Roland platforms (ER-642, ER-641, XP-640, UG-642). It is completely incompatible with previous-generation TrueVIS FlexFire heads (6000006702), VS Series DX6/DX7 heads (6701409010), and DX4 heads (1000002201). Mounting dimensions, fluidic manifolds, and FFC pin assignments are entirely different.
2. Mandatory Head-Rank ID Calibration: After mechanical mounting and ribbon cable attachment, the technician MUST enter the alphanumeric Head-Rank ID value (printed on the barcode label) into the printer via Roland Service Mode. Running without registering the factory voltage rank leads to incorrect drop velocity, satellite misting, or premature piezo actuator burnout.
3. Mandatory FFC Cable & Damper Servicing: Always install brand-new flat flexible head data cables (FFC) concurrently with the printhead. Reusing creased, worn, or ink-contaminated ribbon cables risks shorting the carriage board driver circuits and blowing mainboard driver ICs.
4. Faceplate Maintenance Precautions: Never wipe the coated nozzle faceplate with dry shop wipes or coarse paper towels. Clean only using approved lint-free foam swabs moistened with genuine Roland cleaning solution matching the installed ink line. Inspect and clean the rubber capping station seals and wiper blades regularly to avoid dried ink buildup along the nozzle orifices.
