Five compatible ribbon cartridges

This set contains five LD Products 44173403 black ribbon cartridges built for Okidata Microline 620, 690 and 5720 printers. They are sold new and intended for users who need a ready supply of replacement ribbons for these specific models. Using compatible supplies does not void the printer warranty. The pack is designed for printers purchased within the United States and Canada.

Thermals noise and power draw not applicable

Ribbon cartridges have no active cooling, fans or electrical draw of their own. They operate passively inside the printer mechanism and add no audible noise beyond the normal impact printing sound. No power consumption or thermal figures apply to this consumable.

Printer model compatibility decides fit

The only specification that determines whether this pack works is the printer model number: it fits Okidata Microline 620, 690 and 5720 units purchased in the United States and Canada. Buyers with any other printer model or a unit bought outside those regions cannot use these cartridges.

Questions about this item

How do I install the 44173403 ribbon cartridge in my Microline 620, and what step do people miss?

Open the printer cover, slide the cartridge into the carriage until it clicks, then close the cover; the step often missed is forgetting to remove the protective seal on the ribbon before insertion.

What maintenance or replacement will the 44173403 cartridge need later?

The cartridge is a single-use ribbon; when print becomes faint or spotty, replace the entire cartridge — no separate ink refill or printhead cleaning is required.

What limit appears first during sustained printing with the 44173403 on a Microline 690?

The ribbon length determines the limit; after the rated yield the ribbon exhausts and print quality drops, requiring a fresh cartridge.
