Right ribbon for ML620 / 690 printers

The Oki Data 44173403 is a black nylon ribbon cartridge built for dot-matrix MicroLine 620 and 690 printers. It uses thermal-transfer technology and delivers up to 8 million characters in utility mode. The cartridge is sold individually and ships new.

Check printer model and print mode

Confirm the installed printer is an Oki MicroLine 620 or 690 before ordering. The ribbon is designed for thermal-transfer dot-matrix printing and fits only those two models. Utility-mode yield is rated at 8 million characters; heavier fonts or graphics modes will reduce that figure.

Replaces worn or empty ML620 / 690 ribbons

Swap this cartridge in when the current ribbon fades, snags or reaches end of life. The high character yield suits offices that run continuous forms, multipart invoices or labels daily. Buyers who need colour output or non-impact printing should look elsewhere.

Questions about this item

What comes in the box and is anything else needed to start printing?

The box contains one new Oki Data 44173403 black nylon ribbon cartridge. No extra parts are required; it installs directly into the ML620 or ML690 printer.

There is only one version listed — how do I know this is the right one for my printer?

This cartridge is built for the MicroLine 620 and 690 series. If your printer is one of those models, this is the correct ribbon.

What does the 8 million character yield mean for daily use?

In utility mode the ribbon prints up to 8 million characters before replacement, which reduces change-over frequency for high-volume dot-matrix work.
