OEM Grand-Format Industrial Flatbed UV Component
Original Mutoh DG-48800 Industrial UV Printhead Assembly (PerformanceJet 2508UF)
OEM Part Number: DG-48800 | Industrial Grayscale Drop-on-Demand (DoD) Piezoelectric Multi-Drop UV-LED Printhead Module with Internal Thermal Conditioning
PerformanceJet 2508UF True Flatbed Industrial Architecture Notice
The Mutoh DG-48800 Printhead Assembly is the authentic factory-original OEM replacement component engineered exclusively for Mutoh’s industrial true-flatbed production press: the PerformanceJet 2508UF (PJ-2508UF, 4' × 8' / 1250 × 2540 mm bed). Departing from Mutoh’s desktop and roll-to-roll Epson-based MicroPiezo DX-series designs, this heavy-duty industrial transducer unit features an all-metal stainless steel chassis, an integrated internal heating block with precision thermistor conditioning, and high-frequency multi-drop grayscale firing. It is passivated specifically to withstand aggressive Mutoh UV-LED rigid inks (CMYK, High-Opacity White, and Tactile Varnish) across high-speed scanning gantry passes.
Product Overview
The Original Mutoh DG-48800 Industrial UV Printhead Assembly is an industrial drop-on-demand (DoD) piezoelectric printhead designed for heavy-duty flatbed printing on rigid substrates up to 100 mm (4 inches) thick and weighing up to 50 kg/m² (including corrugated plastics, acrylic sheets, foam boards, aluminum composite panels, wood, glass, and architectural stone). Operating within the expandable 4-head to 6-head staggered carriage array of the PJ-2508UF, this module delivers production speeds up to 20 m²/h while maintaining micron-level dot landing accuracy.
Featuring 1,280 active addressable nozzles arranged across 4 separate rows (320 nozzles per line), the printhead achieves native optical output resolutions ranging from 600 × 300 dpi up to 600 × 1200 dpi. Leveraging advanced multi-drop grayscale waveform modulation, the unit discharges microscopic highlight droplets for smooth continuous tones, clean skin gradations, and sharp 2-point micro-lettering alongside larger drop volumes for dense solid color fills, high-opacity white underbases, and embossed 3D tactile varnish textures. Integrated internal heating dynamically conditions UV monomer viscosity directly behind the acoustic chambers, preventing fluid starvation and jetting deflection during continuous shifts.

Key Features & Operational Advantages
- True Industrial Heavy-Duty Construction: Built with an all-metal stainless steel chassis, providing mechanical resistance against substrate head strikes on thick rigid boards up to 100 mm.
- Internal Thermal Conditioning: Integrated heating elements warm heavy UV-curable monomers directly behind the nozzle acoustic cavity, stabilizing drop velocity across continuous commercial shifts.
- Expandable Staggered Array Production: Operates in the PJ-2508UF gantry across 4 standard heads or upgraded 6-head setups, driving production throughput up to 20 m²/h.
- Direct Drop-In OEM Fitment: Built to exact Mutoh factory specifications, restoring factory drop landing trajectory, dot circularity, and platen height alignment without carriage bracket modifications.
CRITICAL TECHNICAL & SERVICE ADVISORY
1. Absolute Architecture Incompatibility: The DG-48800 is engineered exclusively for the PerformanceJet 2508UF true flatbed. It is completely incompatible with Mutoh's roll-to-roll and tabletop ValueJet printers running Epson MicroPiezo heads (such as DX7 UV DG-45279 on the VJ-426UF / VJ-1626UH or DX5 DG-41914 / DF-49684). Physical dimensions, sub-tank manifolding, heater drive lines, and board protocols do not cross over.
2. Multi-Head Gantry Slant & Registration Calibration: In the PJ-2508UF 4-head or 6-head staggered array, replacing a printhead requires physical dial-indicator mechanical leveling against the gantry reference points followed by software calibration via the Mutoh Maintenance Engineer Software (`MSA`). Re-register the head rank ID values and calibrate inter-head dot placement across bidirectional passes.
3. Mandatory FFC Cable & UV Damper Servicing: Always install brand-new flat flexible head data cables (FFC) and new UV dampers concurrently. Reusing aged, bent, or ink-contaminated ribbon cables risks shorting the carriage board driver circuits, causing catastrophic damage to mainboard driver ICs.
4. Faceplate Maintenance Precautions: Never wipe the metallic nozzle faceplate with dry shop wipes or coarse paper towels. Clean only using approved lint-free swabs moistened with genuine Mutoh UV cleaning solution. Regularly inspect and clean the rubber capping station seals and wiper blades to avoid cured UV ink buildup along the nozzle row caused by UV-LED lamp scatter.
