Universal Calculator Ribbon

Monroe P65M ribbon spools deliver black and true red ink for Monroe printing calculators. The twin-spool cartridge installs directly in every Monroe model. Each spool is sealed in plastic for a shelf life of five years or more.

Cross-Reference Compatibility

This ribbon replaces Nu-Kote BR80C, Porelon PR-511, Porelon 11216 and Dataproducts R3027BR80C. It is manufactured with the heaviest inking saturation on the market. Monroe's exclusive true red ink avoids the orange tint found in other ribbons.

Print Quality Maintenance

High ink saturation reduces smudging during normal calculator operation. Monroe recommends replacing the ribbon after three paper tape rolls to maintain dark print. The sealed packaging preserves ink consistency until installation. No power or thermal considerations apply to this passive ribbon.
