OKI ML790 Printer Ribbons
Shop printer ribbons for your OKI ML790, which uses the OKI R720 printer ribbon. Designed for high-volume multi-part forms and continuous docket printing, this 24-pin impact printer relies on robust fabric ribbons that maintain clear character impression over extended print runs. Installing the genuine R720 ribbon prevents ink faintness across carbon copies. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Ribbon Life Expectations & Page Yield
Impact dot matrix printing measures consumable lifespan by total character impression output rather than standard page coverage percentages. Heavy multi-part docket printing consumes fabric ribbon ink continuously, so keeping steady impression tension ensures consistent legibility on all copy layers.

Ribbon Storage Pro Tip
Always store unopened fabric ribbon cartridges in their original sealed packaging until ready for immediate installation, as exposure to warm ambient air can prematurely dry out the continuous ink lubrication.
Frequently Asked Questions
How do I know when the R720 ribbon needs replacing on my ML790 printer?
Unlike inkjet cartridges that stop suddenly when ink levels report empty, impact dot matrix ribbons gradually fade over time. When the bottom sheets of multi-part dockets become faint or difficult to read, the fabric ribbon ink supply is exhausted and requires replacement.
Does the OKI ML790 ribbon re-ink itself during operation?
The R720 ribbon operates as a continuous fabric loop containing specialized impact ink. While the ribbon continually rotates to distribute ink evenly across characters, once the re-inking reservoir within the physical cassette depletes, the entire ribbon unit must be replaced.
How should spare OKI R720 ribbons be stored to maximise shelf life?
Keep replacement ribbons in their original airtight plastic wrapper at room temperature. Storing ribbon cassettes away from direct heat and sunlight keeps the continuous ribbon fabric lubricated and prevents print faintness upon first installation.
