Applications

Where the DX7 Printhead Excels

The L1440-U2 targets commercial wide-format production on UV and eco-solvent roll printers — the same segment served by Roland VS and Mutoh Valuejet machines across sign shops and print service providers.

UV Wide-Format Printing

UV-cured ink on vinyl, banners, and rigid substrates on Roland VS-640, Mutoh Valuejet 1624, and similar platforms. Stable piezo jetting and greyscale droplets suit high-quality commercial UV output.

Eco-Solvent Signage & Vehicle Graphics

Mild solvent inks for outdoor signage, fleet graphics, and vinyl lettering on Roland RA-640, RE-640, RF-640, and Mutoh Valuejet series — durable prints with smooth colour fills.

Commercial Print Production

High-volume banner, display, and point-of-sale work on industrial wide-format printers. Multi-head setups boost total width while each L1440-U2 module maintains consistent quality across the carriage.

Roland & Mutoh Head Replacement

OEM replacement for worn DX7 / L1440-U2 heads on Roland VS Series and Mutoh VJ Series. Provide your printer model and existing part number — KingJet India stocks genuine Epson L1440-U2 printheads with all-India delivery.

Technical Specifications

Reference data for Roland, Mutoh, and industrial UV/eco-solvent fitment. The L1440-U2 is the UV/eco-solvent variant — do not confuse with L1440-A1 (aqueous ink, 4–5 mPa·s viscosity).

1,440 Nozzles

8 rows at 180 npi — high nozzle density for commercial wide-format UV and eco-solvent output.

40 kHz

Binary mode jetting at 40 kHz for productive pass speeds on Roland and Mutoh printers.

4–19 pL

4-level greyscale droplets for smooth gradients and high-resolution commercial graphics.

UV & Eco-Solvent

6–8 mPa·s viscosity range for UV-cured and mild solvent ink systems.
