Compatible Ribbon Cartridge Set

This pack contains two black ribbon cartridges built for Okidata Microline 620, 690 and 5720 printers. Each cartridge is rated at 6500 pages at 5% coverage under ISO/IEC standard testing. They are sold new and quality-checked for consistent output.

Sustained Print Performance

The ribbons are designed to maintain bold, vivid print quality across long print runs rather than only short bursts. Quality testing targets reliable page yield so that text and forms stay legible through high-volume jobs without early fading or smudging.

Printer Compatibility Check

Confirm that the installed printer is a Microline 620, 690 or 5720 model purchased in the United States or Canada. This set will not work with other Microline models or with units sold outside those regions.

Questions about this item

How much heat or noise does the 44173403 ribbon add during all-day printing on a Microline 620?

The ribbon is a passive consumable; it adds no heat or noise beyond the printer's own mechanism.

Must I already own a Microline 620, 690 or 5720 purchased in the US or Canada for these cartridges to fit?

Yes, the 44173403 set works only with those three models bought in the United States or Canada.

Will the 6500-page yield per cartridge drop if I keep using an older Microline 690?

Yield is rated at 5% coverage per ISO/IEC standard; actual pages depend on print density, not printer age.
