Purpose and Compatibility

This black printer ribbon is manufactured by Oki Data for the Microline 590 and 591 dot-matrix printers. It also fits Unisys AP1327 and AP1359 models. The ribbon uses thermal-transfer nylon material and comes as a single unit ready for installation.

Build and Daily Use

The seamless matrix nylon construction with integrated re-inker reduces the chance of snags or uneven ink distribution during continuous printing. Designed as a direct drop-in cartridge, it requires no special tools or alignment steps when swapping out a depleted ribbon in a busy office environment.

Upgrade Context

This ribbon replaces an exhausted Oki 52106001 cartridge in the same printer models, restoring the rated yield of four million characters. The jump is worth it when print quality fades or the re-inker mechanism no longer feeds fresh ink, situations where a generic refill cannot match the original seamless feed reliability.
