OEM Super-Wide-Format Solvent Component
Original Mimaki SWJ-320 Gen5 4-Channel Print Head Assy (M022650)
OEM Part Number: M022650 / MP-M022650 (Replaces M012639) | Industrial Ricoh Gen5 MH5420 Multi-Drop Grayscale Piezoelectric Solvent Printhead Module (4-Channel Routing)
SWJ-320 Super-Wide Grand-Format Solvent Architecture Notice
The Mimaki M022650 Print Head Assy (officially superseding factory part number M012639) is an authentic OEM industrial piezoelectric drop-on-demand replacement assembly engineered specifically for Mimaki’s 3.2-meter super-wide production platforms: the SWJ-320S2, SWJ-320S4, SWJ-320EA, and SWJ-320EA Plus. Configured with a dedicated 4-channel solvent manifold array and aggressive solvent-resistant cavity bonding, this assembly is purpose-built to handle solvent formulations including genuine Mimaki CS100 and CS200 solvent inks.
Product Overview
The Original Mimaki SWJ-320 Gen5 4-Channel Print Head Assy (M022650 / M012639) is a heavy-duty industrial drop-on-demand (DoD) printhead engineered for continuous grand-format billboard printing, giant building wraps, outdoor PVC banners, fleet livery, and large-scale backlit signage across media widths up to 3,200 mm. Operating in 2-head in-line (S2) or 4-head staggered carriage arrays (S4 / EA), this assembly achieves massive throughput speeds up to 137 m²/h while maintaining precise dot roundness across high-speed scanning carriage travel.
Engineered with 1,280 active addressable micro-nozzles configured across 4 independent rows (320 nozzles per row), the unit achieves native output resolutions up to 1200 DPI across 360, 540, 720, 1080, and 1200 DPI production profiles. Leveraging advanced multi-drop grayscale waveform modulation, it modulates droplet volumes from an ultra-fine 7 picoliters up to 35 picoliters, delivering smooth photo-realistic tonal shading alongside heavy solid color flood fills without banding. Its all-metal stainless steel structure, D33 isolated PZT piezo actuators, and chemically inert manifold seals provide exceptional mechanical longevity under 24/7 industrial production environments.

Key Features & Operational Advantages
- Solvent-Grade Manifold Passivation: Factory-bonded with chemically inert manifold resins resistant to aggressive solvent carriers (CS100/CS200), preventing delamination and internal channel bleed.
- Industrial Gen5 Durability: Solid metal and stainless steel construction with D33 stacked PZT actuators delivers high drop velocity across the wide 3.2m scan stroke, rated up to 100 billion actuations per nozzle.
- Multi-Drop Grayscale Precision: Dynamically modulates drops between 7 pl and 35 pl to render smooth vignettes and sharp characters alongside heavy solid fills in fewer carriage passes.
- Direct Drop-In OEM Replacement: Fully supersedes legacy part number M012639, restoring factory droplet trajectory, dot circularity, and ink firing speeds without carriage bracket alterations.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Platform & Fluid Incompatibility (Solvent vs. UV/Latex Gen5): The M022650 assembly is configured with a 4-channel solvent manifold specifically for the SWJ-320 series. While it shares the core Ricoh Gen5 MH5420 physical dimensions with UV flatbeds (JFX200 M022625), roll-to-roll UV (UCJV300 M026887), and latex printers (JV400-LX M022651), the internal manifold porting, adhesive chemical resistance, and heater thermistor wiring are mapped specifically for solvent controllers. Never install UV or Latex Gen5 modules into an SWJ-320 carriage.
2. Staggered Carriage Slant & Registration Adjustment: On 4-head models (SWJ-320S4 / SWJ-320EA), after mechanical installation the technician MUST carry out optical slant calibration followed by inter-head position calibration (`[#] ADJUST` > `HEAD SP-ADJUST`) to synchronize the front and rear staggered rows across the 3.2-meter beam.
3. Mandatory Head ID Voltage Registration: After physical mounting and cable connection, the technician MUST enter the alphanumeric Head ID value (printed on the barcode label) into the printer’s Service Mode menu (`[#] PARAMETER` > `HEAD ID`). Running a Gen5 head without its specific factory-calibrated voltage table will cause drop deflection, ink misting, or premature piezo fatigue.
4. Faceplate Maintenance Precautions: Never wipe the delicate nozzle face with dry shop wipes or coarse paper towels. Clean only using approved lint-free foam-tipped swabs moistened with genuine Mimaki solvent cleaning solution (SPB-0150 / CS cleaning flush). Inspect and clean the rubber capping station seals and wiper blades regularly to avoid dried solvent ink build-up along the nozzle row.
