F II Type Ink Tubes: universal replacement for legacy Risograph tubes

Genuine Riso ink that dries quickly and keeps color steady.

Product Overview:

If you run high-volume Risograph jobs you know supplies pile up fast. These newly manufactured F II Type ink tubes replace three older part numbers for simpler stocking and fewer surprises. They deliver OEM black ink that dries quickly, resists smudging and stays steady on the shelf, so print runs look the same today as they will next month. Ideal for schools, mailrooms and quick-print shops that outpace office copiers, they work on a long list of Riso models and handle long runs without fuss. Picture neat stacks of pages and a storeroom that finally breathes easy.

Key Features:

• Universal Replacement: Replaces S4254, S6930U and S7605 so you buy one tube and simplify your stockroom.
• Wide Compatibility: Works across EZ, RZ, MZ and SF series printers, so you don't have to match dozens of SKUs.
• High Yield: Designed for long runs, each tube delivers a heavy page count for fewer changeovers and less downtime.
• Fast-drying Emulsion Ink: The emulsion formula dries fast, prevents smears and keeps contrast crisp on next-step finishing.
• Plug-and-Play OEM Design: Genuine Riso tubes install quickly and keep viscosity steady, even after long shelf time.
