Oki Data 52102001 printer ribbon Black 3M characters

Compatible dot-matrix printers

This black nylon ribbon fits Oki Microline 120, 172, 180, 182, 183, 184, 186, 192, 193, 320 and 321 series printers including Turbo and DEC ANSI variants. It is a direct replacement for the original cartridge in those impact printers. The ribbon uses thermal-transfer dot-matrix technology to produce black output on continuous forms or single sheets.

Users needing 3 million characters

Offices that print high-volume invoices, reports or multipart forms on the listed Microline models will reach the rated 3 million character yield before a change is required. Buyers with laser, inkjet or non-Oki dot-matrix printers cannot use this ribbon because the cartridge geometry and feed mechanism are model-specific.

3 million character yield

The ribbon is rated for approximately 3 million printed characters under standard dot-matrix density settings. This single figure determines whether the supply interval matches the workload; environments that exceed this volume will need more frequent replacements.
