Compatible IR-74 Black Rollers

This six-pack of SuppliesMax SKPIR-74 black ink rollers is built as a direct replacement for the Seiko IR-74 cartridge. It fits a wide range of calculators and printers from brands including Texas Instruments, Toshiba, TEC, Sanyo, Unisonic, Radio Shack, NSC, MBO, and Pacesetter. The rollers are manufactured to meet original equipment specifications for consistent print quality.

Sustained Print Consistency

The rollers are produced in ISO-9001, ISO-9002 and ISO-14001 certified facilities using new and recycled components. They are engineered for 110V machines in North America and designed to match or outlast the OEM version during continuous operation. Air-sealed packaging helps preserve ink integrity until each roller is installed.

Simple Drop-In Replacement

Installation follows the standard IR-74 form factor, requiring no tools or adjustments for the listed compatible models. Packaging may vary between shipments but does not affect fit or performance. Buyers needing colour output or a different cartridge format will not be served by this black-only, six-pack configuration.
