Details & Insights
- Nozzle Layout & Resolution
All models use 512 nozzles arranged as two rows of 256, offering a 360 dpi resolution at 180 dpi per row. - Print Width & Size
The effective print width is approximately 36.1 mm, with compact dimensions (approx. 67 mm W × 40 mm D × 63 mm H) and a weight around 95 g - Heater Option
The MH variant includes a built-in heater (up to ~55 °C), enabling better handling of UV/high-viscosity inks.
Non-heated versions are typically used with solvent or oil-based inks. - Ink Compatibility
- LNX (42 pL): Broad compatibility—oil-based, solvent, and UV inks
- LNX-35 (35 pL): Primarily solvent, though some listings note oil/UV compatibility
- MH (14 pL, heated): Supports oil, solvent, and UV inks
- Drop Size vs. Quality vs. Speed
Smaller droplet sizes (like 14 pL) deliver finer detail and smoother gradients—especially when using greyscale modes—and can fire at higher frequencies, improving speed and print precision
