SuppliesMax Acroprint 390127000 Black/Red Printer Ribbon 6/PK

Six-Pack Time Clock Ribbons

This pack contains six black/red ink ribbons built to fit Acroprint 120, 420 and ATR-120 time clock printers. It is intended for businesses that track employee hours on paper cards and need a steady supply of replacement ribbons. The ribbons are manufactured in ISO 9001 and ISO 14001 certified facilities to meet OEM specifications. They are designed for 110V machines sold in the U.S.

Drop-In Installation

Each ribbon cartridge drops into the printer's ribbon bay without tools or calibration; the spool aligns with the drive gears automatically. The most common issue is inserting the cartridge upside down, which prevents the ribbon from advancing and produces blank prints. If the ribbon feeds unevenly, check that the plastic tabs on both ends are fully seated in the guide slots. No firmware updates or driver changes are required.

Black/Red Dual-Colour Output

The single specification that decides fit is the black/red two-colour format matched to Acroprint part numbers 390127000, ACT021150 and S-QR120-BR. Printers that require a single-colour ribbon or a different spool geometry will not accept this cartridge. Buyers who need a single-colour ribbon or a ribbon for a non-Acroprint time clock should look elsewhere.
