OKI ML320T Ribbons
Your OKI ML320T uses the R100/320 ribbon cartridge. The OKI ML320T is a heavy-duty 9-pin dot matrix printer engineered for continuous multi-part forms, invoices, and shipping dockets. Because multi-part impact printing places consistent wear on the ribbon fabric, keeping a spare R100 black ribbon on hand prevents unexpected downtime during high-volume document runs. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected Ribbon Life and Output
Dot matrix ribbons are rated by character count rather than standard ISO page coverage, as text density varies across multi-part carbon forms and continuous rolls. Premium fabric ribbons ensure clear impact transfer across top sheets and underlying copy paper without premature tearing or ink exhaustion.
Ordering Ribbons and Delivery Information
If you issue continuous multi-part invoices or warehouse dockets daily, stocking spare R100 ink ribbons ensures zero disruption during peak dispatch hours.

Pro Tip
Store unused dot matrix ribbon cartridges in their sealed anti-static packaging in a cool, dark environment to prevent the fabric ink from drying out before installation.
Frequently Asked Questions
How do I know when the R100 ribbon needs replacing on an OKI ML320T?
Unlike inkjet cartridges that stop abruptly when empty, dot matrix ribbons gradually fade as the ink stored in the fabric ribbon is exhausted. Replace the ribbon when print on the bottom sheet of multi-part carbon forms becomes difficult to read.
Can the OKI ML320T use fabric ribbons designed for other Microline printers?
The R100/320 ribbon cartridge is specific to the ML320 series and related OKI Microline impact models. Using incorrect ribbon housings can cause printhead jamming or uneven fabric tension during continuous feeding.
Does printing multi-part carbon forms wear out the ribbon faster than single-sheet paper?
The mechanical impact required to strike through carbonless multi-part sets places greater pressure on the ribbon shield, but character count yield remains largely consistent. Ensure printhead gap settings match form thickness to avoid excess ribbon drag.
