Compatible Ribbon Cartridge

The LD Products 44173403 black ribbon cartridge replaces the original Okidata ribbon for Microline 620, 690 and 5720 printers. It is sold as a single unit and is intended for users who need a direct replacement ribbon for those specific dot-matrix models. Buyers with printers purchased outside the United States and Canada should verify compatibility before ordering.

Thermal and Power Behaviour

Dot-matrix impact printers generate heat from the print head rather than the ribbon itself, so the cartridge does not contribute measurable thermal load or noise. Power draw remains governed by the printer mechanism and is unchanged by using this compatible ribbon.

Sustained Use Characteristics

The ribbon feeds continuously during extended print runs and its yield is rated in pages rather than time. Print density stays consistent until the ink is depleted, at which point the cartridge is replaced. No warm-up or cool-down cycle is required between long printing sessions.

Questions about this item

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

Open the printer cover, remove the old cartridge, align the new ribbon between the print head and platen, then advance the ribbon manually using the knob until it moves freely — skipping this tension step causes smudged or blank output.

What part of the 44173403 cartridge will need replacement first during regular use?

The inked ribbon fabric itself is the consumable; once the printed characters fade or become patchy, the entire cartridge is replaced as a single unit.

What limit appears first when printing continuously on a Microline 690 with this ribbon?

The ribbon length determines endurance; after the rated page yield the ink is exhausted and print density drops, requiring a fresh cartridge.
