Product Identity

SuppliesMax CSOIR-40 black ink rollers come in a five-pack and serve as direct replacements for the Casio IR-40 ribbon cartridge. They fit a wide range of Casio, Aurora, B&E and BMC printing calculators and cash registers used in retail, office and accounting environments.

Installation Notes

Each roller slides into the printer compartment without tools and clicks into place in seconds. The only common issue is inserting the roller upside down, which prevents the ink from contacting the paper; re-seating it the right way up restores normal printing immediately.

Decisive Specification

The cartridge is built exclusively for the Casio IR-40 form factor, so it will not work in machines that require a different ribbon size or ink-roller profile. Buyers needing a different ribbon format should verify their model number before ordering.

Questions about this item

How do I confirm the CSOIR-40 roller is printing correctly after installing it in my Casio HR-150?

Print a test receipt; the text should be sharp, evenly black and free of streaks across the full width of the paper.

What comes in the pack and is anything else needed to start printing?

The box contains five black IR-40 compatible ink rollers; no separate ribbon, cartridge or tool is required.

Which pack size should I choose for a Casio PCR-260 that prints daily invoices?

The five-roller pack (CSOIR-40) supplies enough rollers for extended daily use on the PCR-260.
