Supplied in a box, this ribbon is designed for use with multi-part stationery, continuous forms and other impact printing tasks where reliable black output is required for invoices, receipts and official documentation.

Advantages

The ribbon uses high-quality ink formulation that delivers metered ink flow and precisely controlled viscosity for consistent, sharp black text. Its construction reduces wear on the print mechanism and the ribbon shield is precisely tooled to minimise paper jams. In draft print mode the ribbon can deliver up to 2 million characters, providing extended life for frequent printing needs.

How to use

Install the ribbon into the printer following the printer manufacturer's instructions for your OKI model. Ensure the ribbon is seated correctly on the spindles and that the ribbon path is free from twists. After installation, perform a test print to confirm correct alignment and satisfactory black coverage. Replace the ribbon when print density diminishes or when the ribbon reaches the end of its usable life.

Usage recommendations

For best results store the ribbon in its box in a cool, dry place away from direct sunlight. Use standard or draft print modes for high-volume text printing to maximise ribbon lifespan; use higher quality settings only when sharper, darker prints are necessary. Dispose of used ribbons according to local electronic waste guidelines.
